1. Okumenya mu tekinologiya: Okuvvuunuka ebizibu by’amakolero Ekkubo ly’okutunda bbaatule za sodium-ion libadde liremesebwa okuva edda olw’okusuubulagana kw’emirimu-offs mu bintu ebikulu. Hard carbon anodes, ekitundu ekikulu, yayolekagana n’okukontana okw’obuzaale wakati w’okutuuka ku busobozi obw’okudda emabega obw’amaanyi, obulungi bwa Coulombic obusookerwako, n’obungi bwa taapu. Okusoomoozebwa kuno kati kuvvuunukibwa. Ttiimu eyakulemberwa Professor Yufeng Zhao mu Shanghai University yateesa ku nkola ey'obuyiiya eya "Mass Transfer Enhanced Pre-oxidation". Nga balung’amya mu ngeri ey’ekiddukano enkola y’okusaasaana kwa okisigyeni, baanyweza bulungi ebipimo byonna ebisatu ebikulu ebya kaboni omukalu omulundi gumu, ne balaga eddaala ery’amaanyi mu maaso. Mu ngeri y’emu, ttiimu y’abanoonyereza eyakulemberwa Omusomesa Tianshou Zhao mu Southern University of Science and Technology yateekawo likodi ey’ekitalo. Nga bwe kyafulumizibwa mu Energy & Environmental Science, baakola ekintu ekiyitibwa integrated polyanion-layered oxide heterostructure cathode material. Cathode eno yalaga obuwangaazi obw’enjawulo, n’etuuka ku cycles ezisukka mu 100,000 ku ultra-high rate ya 100C ate nga esigazza 72.6% ku busobozi bwayo-nga esukkulumye nnyo ku bulamu bwa bbaatule za lithium{18}}ion ez’ettunzi eziriwo kati era n’elaga obusobozi bwa SIBs okukozesa obulamu obuwanvu-. Kaweefube w’okunoonyereza mu nsi yonna agenda mu maaso. Bannasayansi mu Brown University baazudde amagezi amapya ku nneeyisa ya sodium mu bbaatule, ne bawa enkola empya ey’okukola dizayini ey’okulongoosa ebintu bya anode okulongoosa obutebenkevu n’obungi bw’amasoboza. Mu kiseera kino, abanoonyereza mu Western University mu Canada baakola bbaatule ya sodium ekikalu-state empya nga bakozesa ebintu ebisinziira ku sulfur ne chlorine-, okutumbula obutambuzi bwa sodium-ion n’obukuumi.
2. Okulinnyisa: Obusobozi bw’okufulumya bukwata ekifaananyi Olw’okumenyawo kuno okwa R&D, okukulaakulanya amakolero ga bbaatule za sodium-ion kweyongera amaanyi. EVE Energy efunye obuwanguzi mu kuteeka mu nkola era n’etandika okukola eby’obusuubuzi enkola yaayo esoose ennene-okutereka amaanyi ga bbaatule ya sodium-ion ku kifo kyayo ekya Jingmen. Enkola eno ekozesa obutoffaali bwa NF155L sodium-ion obwesigamye ku nkola ya NFPP (sodium iron phosphate), nga yeewaanira ku bukuumi obw’amaanyi, ebbugumu eringi erikola, obusobozi bw’omutindo ogwa waggulu, obulamu obw’enzirukanya obuwanvu, n’okufulumya kaboni omutono. Ekisinga okweyoleka, Guangde Qingna Technology Co., Ltd. etadde omukono mu butongole endagaano okuzimba pulojekiti y’okukola bbaatule za sodium-ion eza GWh 20 mu Suining, Sichuan. Nga omugatte gw'ensimbi eziteekeddwamu obuwumbi bwa RMB 6, pulojekiti eno ejja kuyamba Suining okukyusa okuva ku "lithium-only" focus okudda ku "lithium-sodium dual-drive" enkola. Wadde nga yatandikibwawo mu August 2023, Qingna Tech eraze okugaziwa okw’amaanyi, mu ngeri etali butereevu ng’erina emigabo mu kkampuni mwenda ng’eyita mu kkampuni zaayo era n’efuna obukadde bwa RMB obusoba mu 100 mu lawundi y’okusonda ssente eya Pre-A eyakulemberwa Yunhe Fangyuan Capital mu January w’omwaka guno.
3. Enkizo enkulu: Emigaso emikulu egy’omuwendo gw’ebintu ebisookerwako Okucamuka okweyongera okwetoloola bbaatule za sodium-ion kusimbye emirandira mu birungi byabwe eby’obuzaale. Ekiwandiiko kya tekinologiya ekyafulumizibwa gye buvuddeko okuva mu kitongole ky’ensi yonna eky’amasannyalaze agazzibwawo (IRENA) kiteeka SIBs ng’eky’okuddako ekiyinza okukolebwa mu kifo kya LIB, ekisobola okukendeeza ku kwesigama ku by’obugagga eby’omu ttaka ebikulu n’okutumbula obugumu bw’omukutu gw’ensi yonna ogw’okugaba bbaatule. Enkizo enkulu eri mu bungi bw’eby’obugagga n’omuwendo. Obungi bwa sodium mu bikuta buli 2.74%, nga businga nnyo ku lithium 0.0065%. Esaasaanyizibwa nnyo era nnyangu okugifuna, ekivaako okutebenkera n’okukendeeza ku ssente z’ebintu ebisookerwako. EVE Energy etegeeza nti obulamu obujjuvu-cycle carbon emissions zaayo NF155L cells zisukka 42% wansi okusinga lithium-ion batteries. Obutoffaali era buwagira ebbugumu eringi ery’okukola okuva ku -40℃okutuuka ku +60℃, ekibufuula obusaanira embeera ez’enjawulo ez’okutereka amaanyi. Abakugu mu by’amakolero bateebereza nti wansi w’okufulumya okunene-, ssente za bbaatule za sodium-ion ziyinza okuba wansi ebitundu 30-40% okusinga eza bbaatule za lithium-ion.
4. Ensalo z’okukozesa: Okutereka amaanyi n’okutambula kw’amasannyalaze Enteekateeka y’okukozesa bbaatule za sodium-ion yeeyongera okutegeerekeka, ng’etunuulidde obutale bubiri obusookerwako: Enkola ennene-Ensimbi z’okutereka amaanyi (ESS): Kino kitwalibwa ng’okukozesa okusookerwako. Abakulira EVE Energy balaga nti ebirungi bya SIBs mu nsaasaanya y’ebintu ebisookerwako n’okutuuka ku by’obugagga bizifuula ennungi ennyo mu kutereka emikutu eminene-n’okutereka amaanyi agasaasaanyizibwa. Emmotoka ez’amasannyalaze ez’amaanyi amatono-(EVs): Kuno kw’ogatta mmotoka ez’amasannyalaze eza nnamuziga bbiri/ssatu-, micro-emmotoka, n’emmotoka ezisaabaze ez’amaanyi amatono-. Qingna Tech etaddewo enkolagana ey’amaanyi n’abakulembeze b’amakolero nga Jinpeng Group ne Lima Vehicle Industry, omuli endagaano y’okugula 1.75 GWh/omwaka ne Jinpeng. Ebintu bya Qingna ebya "layered oxide + large cylindrical cell" biwa density y'amasoboza okutuuka ku 142 Wh/kg, obulamu bw'enzirukanya obusukka mu cycles 6,000, obusobozi bwa 5C charge/discharge, n'okukuuma obusobozi obusukka mu 82% ku -40℃. Okutuuka ku nsi yonna kweyongera. Qingna Tech esindikidde sampuli era etuuse ku bigendererwa by’okukolagana mu bibinja ne kkampuni munaana ez’Abazungu, ng’etunuulidde okukozesa mu kutambula okw’embiro entono, amasannyalaze ag’okutereka mu maka/UPS, n’enkola z’amasannyalaze agakuuma mu munisipaali. 5. Endowooza y’omu maaso: Enjawulo mu tekinologiya n’okukwatagana mu makolero Lipoota ya IRENA eraga nti olw’obwetaavu obweyongera mu nsi yonna obw’okutereka amaanyi n’okusaasaana kw’emmotoka ez’amasannyalaze, bbaatule za sodium-ion zigenda zivaayo nga ezisinga okukekkereza n’okukuuma obutonde bw’ensi eky’omukwano ekijjuliza ku tekinologiya wa lithium-ion. Ebiseera eby’omu maaso bijja kulaba enjawulo mu tekinologiya wa SIB. Amakampuni nga Qingna Tech gagoberera amakubo ag’enkulaakulana agakwatagana ku bbaatule za sodium eziriko layeri, polyanion, ne solid-state. Ttiimu z’abasomesa, okufaananako n’eyo mu Western University, zikyagenda mu maaso n’okukola ku kusoomoozebwa okukulu nga slow ion mobility mu solid-state designs. Mu nsengeka y’amakolero, bbaatule za sodium-ion tezisuubirwa kudda mu kifo kya bbaatule za lithium-ion mu bujjuvu. Wabula, ekifo ekijjuliza kiyinza okuvaayo: lithium-ion eyinza okusigala ng’efuga EVs ezikola obulungi-, ate sodium-ion ayoola ekifo kyayo mu kutereka amaanyi, EV ez’embiro entono, n’eza nnamuziga bbiri-. Okumaliriza Olw’enkulaakulana ya tekinologiya egenda mu maaso n’enjegere z’amakolero ezikula, bbaatule za sodium-ion ziyingira mu kiseera kya zaabu eky’enkulaakulana. Okulinnya kw’omulimu guno tekujja kukoma ku kwawula makubo ga tekinologiya w’okutereka amaanyi wabula era kujja kuyamba okukendeeza ku puleesa ku nkola y’okugaba bbaatule ya lithium-ion, okufuyira amaanyi amapya mu nkyukakyuka y’amasoboza mu nsi yonna.
