Ekirombe kya Greenbushes kyokka ekiddukanyizibwa kkampuni ya Talison Lithium, kyafulumya ttani za Spodumene 798,000 mu mwaka gw’ebyensimbi 2024-2025. Ebikwekweto by’e Chile biggya lithium okuva mu bifo eby’omubisi gw’enjuki, ng’ebikolebwa bituuka ku ttani 49,000 mu 2024. Eggwanga lirina ttani nga obukadde 9 mu bifo ebikuumirwamu, ebisinga obunene mu nsi yonna, wadde ng’emiwendo gy’okuggyamu gisigala wansi w’obusobozi obuyinza okubaawo.

Emmotoka Lithium Battery Chemistry Evolution n'okukola .

Amakolero gano gafunye enkyukakyuka ey’amaanyi eri lithium iron phosphate chemistry, kati ekola ebitundu ebisukka mu 40% ku busobozi bwa bbaatule za EV mu nsi yonna, emirundi egisukka mu ebiri egy’omugabo gwayo ogwa 2020. Enkyukakyuka eno ekuŋŋaanyizibwa mu China, nga bino bibiri-ebitundu bisatu eby’okutunda EV mu 2023 bakozesa bbaatule za LFP. Enkizo enkulu eya kemiko eri mu nsaasaanya-Okufulumya llfp kutambula nga 20% ku buseere okusinga NMC alternatives ate nga kuwa obutebenkevu obw’ebbugumu obw’oku ntikko n’obulamu obuwanvu obw’enzirukanya. Ebisale by’okufulumya bikendedde okutuuka ku doola 55-60 buli kilowatt-essaawa nga September 2024.

Okuzaala Tesla kulaga nti kemiko y’okukkiriza okusukka China. Kkampuni eno yakozesa bbaatule za LFP mu bitundu 30% ku by’efulumya mu 2022, okuva ku bitundu 20% mu 2021, nga kati kitundu kya mmotoka zaayo ez’ensi yonna zikozesa tekinologiya ono. Kumpi enkozesa yonna eya LFP eya Tesla ebaawo mu mmotoka za Shanghai-ekoleddwa, wadde nga kkampuni eno eteekawo enkola ya LFP ey’awaka mu Nevada ng’ekozesa ebyuma okuva mu CATL okugoberera ebisaanyizo by’etteeka erikendeeza ku bbeeyi y’ebintu.

Battery za NMC zisigala nga zisinga mu butale bwa Bulaaya ne North America wadde nga ssente nnyingi, nga zivugibwa amaanyi agasingako ebyetaago by’amaanyi ku mmotoka ennene n’ebanga eddene. Chemistry yeetaaga nickel, cobalt, ne manganese mu migerageranyo egy’enjawulo, ng’emitendera egyakaggwa gisinga kwagala nnyo nikele (NMC 811) okukendeeza ku kwesigama ku cobalt n’okulongoosa amaanyi. Obuzibu bw’okukola bweyongera n’ebirimu nikele ebingi, naye okulongoosa mu bungi bw’amasoboza ku bitundu 10-15% kuwa obujulizi ku kufuga enkola ey’okugatta okwetaagisa.

Tekinologiya wa Sodium-Ekiikirira eky’okuddako ekigenda kikula, nga kumpi amakolero 30 agakola oba agazimbibwa mu nsi yonna, okusinga mu China, nga gonna awamu galimu obusobozi bwa GWh obusukka mu 100. Battery za CATL's sodium-ion zigula ebitundu nga 30% okusinga LFP equivalents naye zituusa amaanyi amatono (75-160 wh/kg okusinziira ku 120-260 wh/kg ku lithium-ion). Kino kiteeka sodium-ion ku mmotoka z’omu kibuga eziyingira n’okutereka ebintu ebiyimiridde okusinga EV ez’omutindo ogw’awaggulu ezeetaaga range esinga obunene. BYD yalangiridde mmotoka ya Seagull ng’ekozesa bbaatule za sodium-ion nga zirina kiromita 300 ku ddoola 11,600, nga ziraga obusobozi bwa tekinologiya ono obw’ebyobusuubuzi.

Obusobozi bw'okufulumya n'enkyukakyuka mu katale .

Obusobozi bw’okukola bbaatule mu nsi yonna bwatuuka ku 3 terawatt-essaawa mu 2024, nga pulojekiti ezirangiriddwa ziyinza okukubisaamu emirundi esatu omuwendo guno omwaka 2029 we gunaatuukira singa gutuukirira mu bujjuvu. Naye, okufulumya okwennyini kuddirira nnyo obusobozi obuteekeddwawo olw’enjawulo mu bwetaavu n’okusoomoozebwa kw’obulungi bw’okukola. Ekituli wakati w’obusobozi bw’amannya n’ebifulumizibwa ebituufu kitondekawo enkyukakyuka z’akatale enzibu ennyo nga oversupply n’ebbula bisobola okubeera awamu mu bitundu eby’enjawulo n’ebika bya kemiko.

Emiwendo gya bbaatule gyakka wansi wa doola 100 buli kilowatt-essaawa mu 2024, nga zisala omusingi omukulu mmotoka z’amasannyalaze gye zituuka ku muwendo gw’ensimbi ezisaasaanyizibwa nga zirina yingini ez’okwokya munda nga tezirina ssente za ssente. Emiwendo mu China gyakka kumpi ebitundu 30% mu mwaka gwa 2024, ne gituuka ku mutindo gwa bitundu 30% okusinga Bulaaya ate 20% wansi wa North America. Enjawulo eno ey’emiwendo gy’ebitundu eraga enjawulo mu nsaasaanya y’abakozi, emiwendo gy’amasannyalaze, okugatta enkola y’okugaba ebintu, n’omutindo gw’okukola.

Okukendeera kwaddiridde emiwendo gya lithium ne gikka ebitundu ebisukka mu 85% okuva ku ntikko yaago eya 2022, wadde ng’emiwendo gisigadde nga 50% waggulu wa 2015-2020 averages. Cobalt, graphite, ne manganese emiwendo gyagwa wansi wa average zaabwe ez’emyaka etaano ku nkomerero ya 2023, nga kiyamba butereevu ku 14% battery pack price reduction wakati wa 2022 ne 2023. Wadde nga emiwendo gya wansi gyanguyiza EV okwettanira, era zisika margins eri amakampuni agasima n’abakola bbaatule, okukaka amakolero okuyingiza.

Emiwendo gy’okukozesa ebintu gyawukana nnyo okusinziira ku kitundu ne kemiko. Abachina abakola bbaatule za LFP bakola kumpi ebitundu 85% okukozesa obusobozi, nga bawagirwa obwetaavu obw’amaanyi obw’omunda mu ggwanga n’obutale bw’okutunda ebweru w’eggwanga. Ebintu bya Bulaaya n’Amerika eby’okukozesa bbaatule za NMC bitera okutambula ku bitundu 50-70% ng’obutale bwa EV obw’omu kitundu bulemererwa okutuukiriza okuteebereza okw’amaanyi okw’okugaziya. Obutakkanya buno buleetedde abamu ku bakola ebintu okulwawo oba okusazaamu eby’okwongera ku busobozi naddala mu Bulaaya nga 2024 EV Sales Plataued wakati mu kukendeeza ku nsimbi z’obuyambi mu Girimaani ne Bufalansa.

Enkolagana ya tekinologiya n’okukola ebintu mu makolero .

Ford’s $3.5 billion Michigan Battery Plant ewa ekyokulabirako ky’ekyokulabirako kino, ng’ekozesa tekinologiya wa CATL wansi wa layisinsi ate ng’ekuuma obwannannyini obujjuvu okugoberera ebyetaago by’ebintu bya Amerika eby’omunda. Enteekateeka eno esobozesa Ford okukola obutoffaali bwa LFP nga tekyenyigiramu kkampuni ya China butereevu, ng’ekola ku nsonga z’ebyobufuzi ate ng’efuna okumanya okukakasibwa-engeri.

Enkola ya Tesla egatta mu -Enkulaakulana y’ennyumba n’enkolagana ey’obukodyo ey’abagaba ebintu. Kkampuni eno ekola dizayini ya bbaatule era n’eyongera okukola obutoffaali bwayo obw’ekika kya cylindrical (4680 format), ate nga enoonya obutoffaali bwa Prismatic LFP okuva mu CATL ne BYD, ne cylindrical NMC cells okuva mu Panasonic ne LG. Enkola eno ey’ensikirano multi-ewa enkyukakyuka mu kemiko, enjawulo mu bitundu, n’okukozesa emiwendo egy’okuvuganya. Tesla’s Nevada facility expansion mulimu layini y’okufulumya LFP eya GWh 10 nga ekozesa ebyuma bya CATL ebitaliiko kye bikola, ekiraga engeri okutambuza tekinologiya gye kubaawo okuyita mu kutunda ebyuma okusinga enkolagana ey’okukola obutereevu.

Abakola ebintu mu Bulaaya beeyongera okukola emirimu egy’awamu n’abakola bbaatule mu Asia okwanguya okukola ebintu mu ggwanga. Kkampuni ya Automotive Cells Company (ACC), omukago wakati wa Stellantis, Mercedes-Benz, ne totalenergies, egenderera okuzimba obusobozi bwa bbaatule okwetoloola Bufalansa, Girimaani, ne Yitale. Northvolt eyatandikibwawo abaali abakulu mu Tesla, yafuna ensimbi ezisoba mu buwumbi bwa ddoola 15 okuzimba obusobozi bwa GWh 150 omwaka 2030 we gunaatuukira ng’ekozesa enkola z’okukola ebintu ezisobola okuwangaala nga zirina ebikozesebwa ebiddamu okukozesebwa. Kkampuni eno ekiikirira omulimu gwa Bulaaya ogusinga okubeera ogw’amaanyi ogw’okwetongola, wadde nga guvuganya n’abakola ebintu abamanyiddwa mu Asia nga balina obumanyirivu obw’emyaka mingi n’obubaka obw’amaanyi.

Abakola ebintu mu Korea bakola mu ngeri ya njawulo, ne bateekawo ebifo byonna eby’ebweru w’eggwanga -ebirina emirimu egy’enjawulo. Kkampuni ya LG Energy Solution’s Poland Plant and SK On’s investments okwetoloola Amerika ekuuma obwannannyini bwa Korea obujjuvu ate nga eweereza obutale bw’omu kitundu. Enkola eno egaba obuyinza bungi ku nkola y’eby’amagezi n’okukola ebintu naye yeetaaga okweyama okunene era ekkiriza obulabe obw’okukola obw’amaanyi.

Enkola ya Gavumenti n’okulowooza ku nteekateeka .

Enkola y’amakolero efuuse enkulu mu kusalawo ku kifo ky’okukola bbaatule nga gavumenti zikkiriza obukulu bwa tekinologiya ono obukulu mu kuvuganya kw’emmotoka n’obukuumi bw’amasannyalaze. Etteeka ly'okukendeeza ku bbeeyi y'ebintu mu Amerika liwa ddoola 7,500 mu musolo gw'abakozesa ku EV ezituukiriza ebisaanyizo by'ebirimu eby'omunda mu ggwanga, naddala nga kiragira nti ebitundu 50% ku bitundu bya bbaatule bikolebwa mu North America era nga tebirina bikozesebwa mu "bitongole bya bweru eby'okufaayo" (okusinga kkampuni z'Abachina). Ebiragiro bino bivuddeko obuwumbi bwa ddoola obusoba mu 70 mu kussa ssente mu Amerika okuva mu 2022.

Enkola ya Bulaaya eggumiza okuzimba enkola z’okugaba ebintu mu bitundu nga ziyita mu kibiina kya European Battery Alliance, nga zitunuulidde 500 GWh ez’obusobozi bw’okufulumya buli mwaka omwaka 2030. Enkola eno erimu obuwumbi bwa €6.1 mu buyambi bwa gavumenti mu pulojekiti eziwera, nga Girimaani, Bufalansa, ne Yitale ze zisinga okusiga ensimbi. Wabula, abakola ebintu mu Bulaaya boolekagana n’obuzibu bw’ensimbi ebitundu nga 20% okusinziira ku bavuganya Abachina ne bwe baba nga tebannalowooza ku njawulo mu bintu n’okutambuza ebintu. Enkola ya EU ey’okutereeza ensalo ya EU, eyassibwa mu nkola mu 2023, eyongera obuzibu nga yeetaaga bbaatule okutuukiriza omutindo gw’okufulumya omukka, ekiyinza okulemesa ebintu ebiyingizibwa okuva mu kkoolaasi-ebisenge by’amasannyalaze ebizito.

China okufuga bbaatule kusibuka ku nkola y’amakolero ekwatagana okumala emyaka amakumi abiri. Ensimbi gavumenti z’ewaayo, okwewola ssente, n’ebiragiro ebyetaagisa kkampuni z’abagwira okukozesa bbaatule z’Abachina okutunda mu ggwanga kyaleetawo akatale k’awaka akanene akaasobozesa abakola ebintu okutuuka ku by’enfuna ebitaliiko kye bifaanana. CATL yokka yafuna ensimbi nnyingi ez’amakampuni ga China okusinga kkampuni endala yonna okuva mu 2023 okudda waggulu, n’ewa ensimbi enzirukanya y’okunoonyereza n’okukulaakulanya okw’amangu n’okugaziya mu nsi yonna mu ngeri ey’amaanyi. We bwazibidde nga September 2024, obuwagizi bwa gavumenti buno bukyagenda mu maaso wadde nga waliwo obusobozi obusukkiridde mu makolero.

Okusika omuguwa mu by’obufuzi kweyongera okukola okusalawo kw’okukola. Ekitongole ky'ebyokwerinda mu Amerika kyayongera CATL ku lukalala lwakyo olwa "Cinese Military Companies" mu January 2025, nga kikugira endagaano z'ebyokwerinda n'ebitongole ebikozesa ebintu bya CATL. Ababaka ba Palamenti mu Amerika baleese ekiteeso ky’okwongera CATL ku nkalala z’okuwera okuyingiza abantu mu ggwanga wansi w’etteeka lya Uyghur Forced Labour Prevention Act, wadde nga kkampuni eno egaana byonna ebigambibwa nti waliwo abakozi abakaka okukola emirimu mu nkola yaayo ey’okugaba ebintu. Ebikolwa bino, nga bigattiddwa wamu n’ebiteeso by’obufuzi bwa Trump ku misolo egisobola okutuuka ku bitundu 150%, bisika abakola ebintu by’Abachina okutandikawo ebifo ebifulumya ebintu mu butale obugendererwamu okusinga okutunda ebweru bbaatule eziwedde.

Tekinologiya w’okukola n’okuyiiya enkola .

Okukola obutoffaali bwa bbaatule kuzingiramu emitendera egy’obutuufu egy’amakumi egyetaagisa embeera ezifugibwa n’obwegendereza n’okumanya enkola ey’obwannannyini ekitwala emyaka okukulaakulana. Enkola eno etandika n’okutabula ebintu ebikozesebwa mu kukola ebyuma mu biwujjo, okubisiiga ku bipande by’ebyuma (copper for anodes, aluminium for cathodes), n’okunyiga okutuuka ku buwanvu obutuufu ne density. Olwo obusannyalazo buno ne busalibwa, busimbibwa oba buzimbiddwa n’ebyawufu, ne buyingizibwa mu mbeera z’obutoffaali, ne bujjula amasannyalaze, ne busibibwa, era ne bukolebwako enzirukanya y’okutondebwa ebiteekawo omulimu gw’obusannyalazo ogusooka.

Enkola ya Catl-to-Pack (CTP) emalawo layeri ya modulo ey’ennono, n’eteeka obutoffaali butereevu mu pack za bbaatule. Enkola eno eyongera okukozesa obuzito ebitundu 15-20%, ekubisaamu emirundi ebiri obulungi bw’okufulumya ng’ekendeeza ku mitendera gy’okukuŋŋaanya, n’esala ku kubala ebitundu 40%. Energy density ebuuka okuva ku 140-150 WH/kg okutuuka ku 200 Wh/kg ku mutendera gwa pack, okuvvuunula butereevu okutuuka ku bbanga ly’emmotoka okweyongera oba okukendeeza ku sayizi ya bbaatule okusobola okukola ekyenkanankana. Kigambibwa nti bbaatule ya CTP 3.0 "Qilin" etuuka ku busobozi bwa bitundu 13% okusinga obutoffaali bwa Tesla 4680.

Tesla's 4680 cell format ekiikirira ekkubo ery'enjawulo ery'obuyiiya, okwongera ku cylindrical cell diameter okuva ku 21mm okutuuka ku 46mm n'obuwanvu okutuuka ku 80mm. Enkola ennene ekendeeza ku nsaasaanya y’okukola buli kilowatt-essaawa nga enyanguyiza okukuŋŋaanyizibwa (obutoffaali obutono obwetaagisa buli pack) n’okulongoosa okusaasaanya ebbugumu. Design ya Tabless electrode esala ku buziyiza obw’omunda, okusobozesa okucaajinga amangu n’okufuluma kw’amaanyi amangi. Tesla egamba nti 5x okulongoosa amaanyi, 6x eyongera amaanyi, ne 16% range improvement okusinziira ku 2170 cells, wadde nga okutuuka ku bino specifications ku production volumes kizuuliddwa nga kizibu.

Ekizigo ekikalu eky’amasannyalaze, nga kikolebwa Tesla n’ebirala, kimalawo amaanyi-Eddaala ery’okukaza ery’ekizimbulukusa ery’amaanyi mu kukola eby’ennono. Ekizigo ekibisi eky’akasannyalazo kyetaagisa okusiiga ebiwujjo by’obusannyalazo obulimu ebisengejja (okusinga N-methyl-2-pyrrolidone), olwo ne bifuumuula ebizimbulukusa ebyo mu fumbiro eddene nga binywa amaanyi ag’amaanyi n’ekifo eky’ekkolero. Okusiiga okukalu kukozesa ebintu bya pawuda butereevu, ekiyinza okukendeeza ku nsaasaanya ya kapito ebitundu 10-20% ate enkozesa y’amasoboza okutuuka ku bitundu 30%. Naye, okutuuka ku mutindo gw’obusannyalazo ogugeraageranyizibwa n’embiro z’okukola bikyali bizibu, ekikoma ku kussa mu nkola eby’obusuubuzi.
