Njawulo ki eri wakati wa bbaatule ya lithium ne alkaline?

Nafuna essimu mu kiseera ky’obutiti ekyayita okuva ew’omukungu avunaanyizibwa ku kugula ebintu mu kifo eky’okuterekamu ebintu eby’amaanyi mu Wisconsin. Yali afiiriddwa sensa 8 ez’okulondoola obutonde bw’ensi olw’okwonooneka kwa bbaatule, era yali anyiize kubanga yali tasobola kuzuula kiki ekigenda obubi. Ttiimu ye ebadde ekozesa Duracell Procell Alkalines, ng’ekola enteekateeka y’okukyusa buli luvannyuma lwa myezi esatu eyandibadde ekuuma ekimala. Sensulo zaali ziweebwa omutindo gwa bbaatule, ebiseera eby’okuddaabiriza byawandiikibwa, buli kimu nga kitunudde ddala ku lupapula.

 

Obuzibu bwali bwa bbugumu. Ku -18℃, nga eno ye standard for frozen goods storage, battery za alkaline teziyisa mu ngeri datasheets zaabwe gye ziraga. Obusobozi bukka mpozzi 10-20% ku bipimo, era obutoffaali bwa alkaline bwe butuula ekitundu nga bufuluma mu mbeera ennyogovu, bukulukuta. Potassium hydroxide electrolyte eyita mu sensa ekwatagana okumala wiiki ntono. Omuntu yenna we yagguddewo yuniti okuddaabiriza, okukulukuta kwali kusaasaanidde mu circuitry. Omugatte gw’okufiirwa, ddoola nga 12,000.

Yali akoze math ku unit costs, checked compatibility specs, yagoberera emitendera gyonna egya bulijjo egy’okugula. Tewali n’ekimu ku ebyo ekyafulumira ku kizibu ky’ebbugumu kubanga tewali alowooza kubuuza ku nkola y’ennyogoga ng’agula bbaatule za AA.

Emboozi eyo okusinga y’ensonga lwaki mpandiika bino. Enjawulo wakati wa lithium ne alkaline si nzibu ku mutendera gwa kemiko, naye ebikwata ku nkola y’emirimu biziikibwa wansi w’ebirimu ebigerageranya eby’enjawulo ebitayamba muntu yenna kusalawo kwa ddala kugula.

Enkyusa ennyimpi .

Enkyusa empanvu erimu okutegeera lwaki enjawulo ezo ziriwo era nga mu butuufu zikwata ku nkola zo entongole. Ensobi ezisinga ez’okugula ebintu ze ndaba ziva mu kusiiga ekika kya bbaatule enkyamu ku nkozesa y’okukozesa obunafu bwayo we bufulumira.

Obusobozi wansi w'omugugu: awali enjawulo entuufu eraga

Okugerageranya kwa bbaatule okusinga kussa ku maanyi ga maanyi ne vvulovumenti. Ennamba ezo zikulu, naye si amakampuni we gafiirwa ssente. Ensonga ekwata ddala ku nsaasaanya y’emirimu y’obusobozi bw’obusobozi obugereddwa bw’osobola okukozesa mu butuufu wansi w’akakwakkulizo k’ekyuma kyo akaliwo kati.

Akatoffaali ka AA aka alkaline kaweebwa ekipimo kya 3000mAh. Ekipimo ekyo kiva mu kugezesebwa kw’okufulumya ku kasasiro omutono, mu bujjuvu 25mA oba wansi. Sikaani ezikwatibwa mu ngalo ezisinga zikozesa okusika 500-800mA. Leediyo ez’engeri bbiri zisika oba waggulu. Ku 800mA discharge, 3000mAh alkaline cell eyo etuwa ekintu nga 1000mAh y’amaanyi agasobola okukozesebwa. Osasula obusobozi bw'otosobola kufuna.

Ensonga eri nti okuziyiza okw’omunda. Akatoffaali ka alkaline akapya kalina obuziyiza obw’omunda okwetoloola 0.15Ω, nga ka wansi ekimala obutakola kinene. Naye alkaline chemistry erina engeri etafuna kuteesebwako kimala mu mbeera z’okugula: okuziyiza okw’omunda kweyongera nga obutoffaali bufuluma. Mu kiseera w’okozesezza ebitundu 90% eby’obusobozi bw’enzikiriziganya, okuziyiza okw’omunda kuba kulinnye okutuuka ku 0.75Ω oba okusingawo. Wansi w’okukuba akasannyalazo akawanvu, obuziyiza obwo bukyusa ekitundu ekinene eky’amasoboza agatereddwa agasigaddewo mu bbugumu okusinga okufuluma okw’omugaso. Battery tefudde mu ngeri ya kuggwaamu; Kifudde mu ngeri nti tekikyasobola kutuusa current ku voltage ya mugaso nate.

Lithium Chemistry terina kizibu kino kumpi ku ddaala lye limu. Obuziyiza obw’omunda busigala nga bunywevu okuyita mu nsengekera y’okufulumya, ekitegeeza nti 3500mAh lithium cell mu butuufu egaba kumpi 3500mAh oba osika 100mA ku remote control oba 2A ku kikozesebwa ky’amasannyalaze.

Nakola n'ekifo eky'okugabira abantu omwaka oguwedde ekyali kimaze emyezi nga kigonjoola ebizibu "ebitaliimu" Zebra TC52. The spec sheet said 8-essaawa runtime, baali bafuna essaawa 3, era buli omu alowooza nti waliwo ekikyamu ku hardware. Turned out scanners zaali nnungi. Battery za alkaline under load just totuusa busobozi bwazo rated. Ssenda ku li-ion eddaamu okucaajinga, sikaani ze zimu zaatandika okukuba 7+ essaawa. Enjawulo yali mu bbaatule zonna.

Omulimu gw’ebbugumu .

Eno ye spec eyakwata kkampuni ya Wisconsin off guard, era osanga y’ensonga esinga obutasiimibwa mu kulonda bbaatule okukozesebwa mu makolero.

Ku bbugumu erya bulijjo, alkaline ne lithium byombi bikola okumpi n’ebigezo byabwe ebigereddwa. Ebbugumu bwe ligenda likendeera, ekituli kiggulawo nnyo. Alkaline chemistry esinga okuwuliziganya n’ennyogovu kubanga ensengekera z’amasannyalaze zikendeera era obuziyiza obw’omunda bweyongera. By 0℃, otunuulira 50-70% ku busobozi obugereddwa. By -18℃, nga eno ye setpoint eya bulijjo ey'okutereka frozen, alkaline ekuuma mpozzi 10-20% obusobozi-effectively useless for most applications. Ku -40℃, mu bukulu kiri zero.

Lithium ekuuma obusobozi bwa 70-80% ku -18℃era ekyatuusa 50-60% ku -40℃. Okugezesa mu nnimiro okwafulumizibwa ku Backpackinglight.com kwalaga alkaline okumala eddakiika nga 25 ku 0℃F mu mbeera y’omugugu efaanagana nga lithium yamala eddakiika 150. Eyo ya njawulo 6× mu kiseera ekituufu eky’okudduka okuva ku bbugumu lyokka, nga tekyesigamiziddwa ku nsonga z’obusobozi wansi w’omugugu.

The practical Implication: Bw’oba ​​oddukanya cold chain logistics, outdoor infrastructure, entambula ya firiigi, oba ekifo kyonna mu mbeera y’obudde ey’obukiikakkono ebyuma mwe biyinza okubeera nga bifunye ebbugumu ery’okutonnya, bbaatule za alkaline si ssente-okukekkereza. Zino kizibu kya kwesigika ekijja okuleeta ssente nnyingi mu kulemererwa, okukyusa embeera ez’amangu, n’okwonooneka kw’ebyuma okusinga okukekkereza kwa yuniti kwonna.

The flip side is also worth stating: Bwoba okolera mu mbeera y'obudde-econtrolled environments with stable temperatures between 15-30℃, togenda kulaba mugaso gwa Lithium's cold tolerance era tewali nsonga lwaki okisasulira.

Omugatte gw’ensimbi ezisaasaanyizibwa mu bwannannyini .

Okugerageranya emiwendo gya yuniti (unit price comparisons) we wali okugula bbaatule okusinga okutambula obubi. Okubala kulabika nga kweyoleka-alkaline AAS zigula $0.50-1.00, rechargeable lithium equivalents zigula $5-10, lwaki omuntu yandisasudde 10× more for batteries?

Kubanga per-Unit cost si kye ddala osasula ku lifecycle y'okuteeka mu nkola.

Ensonga ya Breakeven ku 6 enkozesa ye namba enkulu. Ekyuma kyonna ekiyita mu bbaatule emirundi egisukka mu 6 okusinga obulamu bwakyo obw’obuweereza kigula kitono okukola ku lithium eddaamu okucaajinga okusinga ku alkaline. Ekituli kigaziwa mangu oluvannyuma lw’ekyo. Ku byuma bya buli lunaku-, otunuulira lithium egula ebitundu nga 2% ku bisale bya alkaline mu bbanga ery’emyaka 10.

Naye mu butuufu, ssente za bbaatule zennyini zitera obutaba na nsonga nkulu. Nze ndabye ebifo nga swap labor esukka ku battery purchase cost by 3-4×. Ekikwekweto kya 120-scanner ekikyusa bbaatule emirundi ebiri mu wiiki kimala essaawa ezisukka mu 1,200 buli mwaka nga bakyusa bbaatule zokka. Ku $25/hour loaded labor cost, ekyo kiri $30,000+ mu bakozi olw’omulimu ogubula gwonna ne lithium eddaamu okucaajinga ne dock charging.

ROI data okuva mu kukyusa kwennyini .

Nja kugabana ennamba ezimu okuva mu pulojekiti ze tubaddemu oba ze tubadde nazo. Zino zibeera za makolero, so si kukozesa kwa bakozesa, naye enkyukakyuka mu kusalawo zikola ku muzingo gwonna mw’osaasaanya ddoola ezisukka mu bikumi bitono buli mwaka ku bbaatule.

Kkampuni ya 3PL eyesigamiziddwa ku Texas-ekyusa emmeeri ya 50-okusonyiwa okuva mu lead-asidi okudda mu lithium-. Enkola ya bbaatule ey’enjawulo okusinga obutoffaali bwa AA, naye okugeraageranya kwa kemiko y’emu. Okuteeka ssente mu kusooka kwali kwa maanyi, naye okuteebereza kw’omwaka 8-kwa kwalaga obukadde bwa ddoola 2.9 mu kutereka okuva mu kugenda mu maaso n’okukendeeza kwa lead-acid-56% mu nsaasaanya yonna eyeekuusa ku bbaatule. Payback period yali ya myezi 31. Okukekkereza kwava mu kumalawo ekisenge kya bbaatule ekya sq ft 480 ekiweereddwayo, okukendeeza ku kuddaabiriza buli lunaku okuva ku ssaawa 4.5 okutuuka ku ddakiika nga 20, n’okusala ebyuma okuyimirira okuva ku bitundu 12% eby’obudde bwa ssifiiti okutuuka ku bitundu 2%. Ekyo kiva mu kunoonyereza okwakolebwa UGOWORK okwafulumizibwa mu 2024.

Ku mutendera omutono, ekifo we twakoleranga butereevu kyalina sikaani 120 ezikwatibwa mu ngalo nga ziyita mu 480 alkaline AAS buli wiiki. Battery ya buli mwaka yali $18,720, nga kwogasse essaawa 1,248 ez'okukola swap labor. Bakyusa ne bafuuka Li-Ion nga balina dock charging ku $14,400 upfront-batteries nga kwogasse n'ebikozesebwa mu kucaajinga. Amasannyalaze agagenda mu maaso gali ku doola 960/omwaka. Payback hit ku myezi 9. Oluvannyuma lw’ekyo, bakekkereza ddoola nga 17,000 buli mwaka nga zero zitaataaganyizibwa mu nkola okuva mu kukyusa bbaatule.

Omusono gukwatagana: Okuteeka ssente mu maaso waggulu, okusasula amangu okusinga ebyuma ebisinga obungi eby’omugatte, okutereka okw’amaanyi okugenda mu maaso oluvannyuma lw’okukuba.

Obulabe bw'okukulukuta .

Kino tekifuna kufaayo kumala mu kukubaganya ebirowoozo ku kulonda bbaatule, oboolyawo olw’okuba kizibu okugera omuwendo okutuusa lwe kikutuukako.

Battery za alkaline zikozesa potassium hydroxide nga electrolyte yazo. Koh alina obulwadde bwa corrosive. Obutoffaali bwa alkaline bwe buvuba-era bukola okukulukuta, emirundi mingi okusinga abakola ebintu okwagala okukkiriza-electrolyte elumba ebyuma ebikwatagana era esobola okusaasaana mu circuitry. Oluusi osobola okuyonja obulabe n’otereka ekyuma. Oluusi ebyuma bisaanyizibwawo.

Obulabe bw’okukulukuta bweyongera n’emyaka, okufulumya ekitundu, n’okuvuga ebbugumu. Ebyuma ebituula nga tebikozesebwa wakati w’okuyiwa bye bisinga okubeera mu bulabe. Nze ku lwange ndabye pallets za leediyo ez’amangu nga ziwandiikiddwa kubanga bbaatule za alkaline zaafuluma mu myezi 18 nga sitoowa okutereka. leediyo zaali zirinze okuteekebwawo kw’okuddamu kw’akatyabaga okutajja, era omuntu we yakutula emisango egy’okuddaabiriza, okukulukuta kwali kusaasaanidde wala nnyo okubataasa.

Kino si kizibu kimu-brand. Mala akaseera ku R/Batteries oba ku mukutu gwonna ogwa Electronics Engineering Forum ojja kusanga okwemulugunya okukulukuta ku buli kika kya alkaline ekikulu-Duracell, Energizer, sitoowa, si kikulu. Oba ensonga egenda ekendeera okufuga omutindo mu mulimu gwonna oba kyokka okwongera ku lipoota ku yintaneeti ekifuula ebizibu ebiriwo okulabika, enkola eriwo. Kakasa ggwe kennyini bw’oba ​​oyagala; Threads si nzibu okuzuula.

Lithium chemistries zikozesa non-amasannyalaze ag’omu mazzi. Lithium omukulu (non-rechargeable) ne lithium-ion (rechargeable) zombi zirina okumpi-akabi k'okuvuba ziro mu mbeera eza bulijjo. Ku kyuma kyonna ekituula nga tekikola wakati w’enkozesa-enkola ez’amangu, ebyuma ebikuuma, ebikozesebwa mu sizoni, ebyuma eby’obukuumi-Engeri eno yokka esobola okulaga obutuufu bw’omuwendo gw’ebbeeyi ku alkaline.

Okwefuula -Okufulumya n'okutereka .

Kino kye kitundu ekimu nga alkaline erina enkizo eya nnamaddala, era kikulu ku nkola ezenjawulo.

Battery za alkaline self -zifulumya ku 2-3% buli mwaka. Osobola okuziteeka ku shelf n'odda 7-nga wayise emyaka 10 ng'obusobozi obusinga obungi bukyaliwo. Lithium omusookerwako asinga n’okusingawo-nga 1% buli mwaka ye-afulumya n’obulamu bw’emyaka 15-20. Rechargeable Lithium-ion esinga ku metric eno, okufiirwa 3-5% buli mwezi, ekitegeeza nti tosobola kumala ga shelf li-ion inventory n'ogyerabira.

Ku bifo eby’amangu ebyetaaga okutuula nga tebikwatiddwako okumala emyaka okutuusa nga biyitiddwa-Ebitabo ebitasaanyiziddwa, empuliziganya ey’okutereka, ebyuma ebikuuma obukuumi-Primary Lithium y’enkola esinga obulungi. Obulamu bw’emyaka 15-20 nga bugattibwa wamu n’okumpi-akabi k’okukulukuta kwa zero kakuba alkaline wadde nga okwefuula-emiwendo gy’okufuuwa, kubanga empisa za alkaline ez’okukulukuta zifuula obutasaana ku kutereka okw’ekiseera ekiwanvu nga tekuli kulabirirwa.

Bw'oba okuuma rechargeable Li-ION inventory, storage state of charge nsonga okusinga abantu abasinga bwe bakitegeera. Okutereka Li-Oyoni ku full charge kyanguyiza okuvunda kw’obusobozi. Ku bbugumu eri waggulu, lithium-obutoffaali obuterekeddwa ku 100% embeera y’omusannyalazo busobola okufiirwa okutuuka ku bitundu 35% ku busobozi bwabwo buli mwezi. Enkola entuufu kwe kutereka ku 40-60% SOC nga erina enzirukanya y’okukebera buli luvannyuma lwa kiseera. Nze ndabye amakampuni nga gafiirwa enkumi n’enkumi z’ensimbi mu battery inventory ezaaterekebwa nga zijjudde nga zisasulwa wansi w’okulowooza nti full charge yali etegeeza ready okuteeka mu nkola.

Okukozesa-Okulonda okwetongodde .

Mu kifo ky'okuteesa okwa bulijjo, laba engeri okulonda gye kumenyawo nga bakozesa ensonga:

Ensobi z'okugula nsigala ndaba .

Okukebera ku muwendo gwa yuniti nga tewali TCO modeling.Eno y’esinga okumanyibwa. Okugula ebintu kujaguza okutereka $0.05/battery ate okusalawo okukulu okukozesa alkaline costs 10× okusinga lithium bwe kwandibadde mu kiseera ky’okuyiwa. Zimba enkola ya TCO entuufu nga tonnaba kuteesa ku bbeeyi-okussaamu akabi k’okuwanyisiganya, okusuula, n’obulabe bw’okwonooneka kw’ebyuma.

Okukozesa obusobozi bw’obusobozi okuva mu mbeera y’okufulumya ey’erinnya.Olupapula lwa Device Spec bwe lugamba essaawa 8 ez’okudduka, ekyo kisinziira ku busobozi bwa bbaatule ku mbeera y’okugezesa omukozi, so si current yo entuufu ey’okukola. Ddala runtime ku real operating load eyinza okuba 40% ku spec oba wansi. Singa runtime ekulu, saba discharge curves ku current draw yo yennyini, si kirungo kyonna optimal test embeera manufacturer gyeyakozesa.

okubuusa amaaso ebbugumu mu specification.Ebyuma bifuna okuteekebwa mu bifo eby’enjawulo eby’okuterekamu amazzi oba ebweru, alkaline eremererwa, buli muntu anenya ebyuma oba enteekateeka y’okuddaabiriza. Okulonda bbaatule kwali kukyamu okuva ku ntandikwa. Singa ebbugumu ly’okukola ligenda wansi wa 5℃n’obutakyukakyuka bwonna, alkaline y’esinga okusalawo.

Non-Batteries za OEM mu byuma ebikulu.Waliwo omusango oguwandiikiddwa okuva mu ddwaaliro ly’abaana mu ggwanga lyonna ng’ebyuma ebilondoola abalwadde byalemererwa mu nnaku 30 oluvannyuma lw’abakozi okuteeka bbaatule ez’okusatu{1}}Okukyusa akabaga. Obutoffaali obutali bwa- tebulina circuit entuufu ez’obukuumi era ne bwonoona ebyuma. Enkola y’eddwaliro kati elagira OEM-Battery zokka ku byuma byonna eby’okulabirira abalwadde abayi. Kino kyafulumiziddwa mu lupapula lwa AAMI Biomedical Instrumentation & Technology Journal. Ku nkola yonna okulemererwa kwe kutwala akabi k’obukuumi oba ebivaamu eby’amaanyi mu by’ensimbi, ssente eziterekeddwa okuva mu bbaatule ez’oluvannyuma lw’okutunda tezisaanira kubikkulwa.

Okutereka lithium eddaamu okucaajinga ku full charge.Yanguwa okuvunda amangu okusinga obugaali bwe bukola. Bw'oba okuuma Li-Ion Inventory, teeka ku 40-60% SOC era ossa mu nkola check cycles.

Abagaba bbaatule ezituukiriza ebisaanyizo .

Bw’oba ​​weekenneenya abasuubuzi, laba kiki ky’olina okusaba:

• Discharge curves ku mbeera z’omugugu eziwera. Omugabi asobola okuwa data y’obusobozi yokka ku muwendo gw’okufulumya ogusinga obulungi oba tategeera kintu kye oba akweka omulimu omubi ogwa waggulu-okufulumya amazzi. Mu ngeri yonna, so si muntu gw'oyagala okulambika bbaatule ku nkola za waggulu-okufulumya amazzi.
• Data y’omutindo gw’ebbugumu mu bbanga lyo eryennyini ery’okukola. Tokkiriza kisenge-Ebifaananyi eby'ebbugumu eri ebyuma ebigenda mu kutereka ennyogovu.
• Data y'obuziyiza obw'omunda ku butoffaali obupya n'enkomerero-ey'okuteebereza kw'obulamu. Kino kikubuulira engeri bbaatule gy’egenda okukolamu wansi w’omugugu nga bwe ekaddiwa, so si ddi lw’eba fresh yokka.
• satifikeeti z’obukuumi-UN38.3 ku by’entambula, UL ne IEC 62133 olw’obukuumi bwa lithium. Bino birina okuba ebisaanyizo eby’okutandika.
• Ebiragiro bya waranti ebisibiddwa ku bulamu bwa cycle okusinga obudde bwa kalenda. Calendar-Waranti ezisinziira ku bbaatule tezirina makulu ku bbaatule; Enzirukanya-Ebigambo ebyesigamiziddwa ku nkola biraga obwesige mu kukola kwennyini.
• Enkolagana entuufu ey’okuddamu okukola ebintu, si bigambo ebitali bitegeerekeka ebikwata ku kukwata okusuula. Lithium is 95% recyclicable with residual material value, naye ekyo kikulu nnyo singa wabaawo pulogulaamu entuufu okugikwata.

bye tukola .

Polinovel ekola bbaatule za lithium okukozesebwa mu makolero, eby’obusuubuzi, n’eby’enjawulo. Ttiimu yaffe eya yinginiya ekolagana n’ebibinja by’okugula n’emirimu okukoppa TCO ku nsonga z’okukozesa ezenjawulo, enkola y’okugezesa wansi w’embeera entuufu ey’okuteeka mu nkola okusinga okuteebereza kw’empapula z’amawulire, n’okugonjoola ebizibu ebikwatagana n’ebyetaago ebya nnamaddala.

Tetugenda kukugamba nti Lithium bulijjo kye kiddamu ekituufu-Waliwo enkola nnyingi nga alkaline ekola amakulu mangi, era tujja kukugamba nti bwe kiba nga kituufu ku mbeera yo. Kye tujja okukola kwe kuddukanya ennamba entuufu n’okukuwa data okusalawo ku.

Bw’oba ​​weekenneenya enkyukakyuka ya bbaatule oba ng’oyagala okukakasa oba enkola yo ey’akaseera kano ya ssente-esinga obulungi, tuuka ku polinovelpowbat.com n’osaba okwekenneenya kwa TCO. Tutera okukyusa okwekenneenya okusooka mu wiiki emu.
