Battery za lithium-ion zisiimibwa olw’amaanyi gazo amangi, obulamu bw’enzirukanya empanvu, n’omuwendo omutono ogw’okwefulumya. Okutegeera engeri bbaatule zino gye zikolamu kikulu nnyo.
Ebitundu ebikulu ebya bbaatule ya lithium-ion mulimu anode, cathode, electrolyte, ne separator. Ebintu bino bikolagana okutereka n’okufulumya amaanyi mu ngeri ennungi. Anode etera okukolebwa mu graphite, ate cathode erimu lithium metal oxide. Electrolyte ye lithium salt solution mu organic solvent, ate separator ye membrane ennyimpi eziyiza short circuits nga ekuuma anode ne cathode nga zaawukana.
Enkola z’okusannyalala n’okufulumya bbaatule za lithium-ion ze nsonga enkulu mu nkola yazo. Enkola zino zirimu okutambula kwa ion za lithium wakati wa anode ne katodi okuyita mu kisengejja.
Battery ya lithium-ion bw’ekuba, lithium ions zitambula okuva ku katodi okudda mu anode. Entambula eno ebaawo kubanga ensibuko y’amasannyalaze ag’ebweru, ekozesa vvulovumenti okuyita mu bitundu bya bbaatule. Voltage eno evuga lithium ions okuyita mu electrolyte ne ziyingira mu anode, gye ziterekebwa. Enkola y’okucaajinga esobola okumenyeka mu mitendera ebiri emikulu: ekitundu kya kasasiro (CC) ekikyukakyuka ne phase ya vvulovumenti etakyukakyuka (CV).
Mu kiseera kya CC phase, akasannyalazo akanywevu kaweebwa bbaatule, ekivaako vvulovumenti okweyongera mpolampola. Battery bw’emala okutuuka ku limit yaayo esinga obunene, chajingi ekyuka n’egenda ku CV phase. Mu mutendera guno, vvulovumenti ekwatibwa nga tekyukakyuka, era akasannyalazo kakendeera mpolampola okutuusa lwe katuuka ku muwendo omutono. Mu kiseera kino, bbaatule eba ejjude.
Okufulumya bbaatule ya lithium-ion kizingiramu enkola ey’okudda emabega, nga lithium ions zitambula okuva ku anode okudda mu katodi. Battery bw’eyungibwa ku kyuma, ekyuma kiggya amasannyalaze okuva ku bbaatule. Kino kireetera amasannyalaze ga lithium okuleka anode ne gatambula okuyita mu kiyungo ky’amasannyalaze okutuuka ku katodi, ne kikola omusinde gw’amasannyalaze ogukola amaanyi g’ekyuma.
Enkola z’eddagala mu kiseera ky’okufulumya mu bukulu ze zidda emabega w’ezo nga zicaajinga. Lithium ions ziyingiza (yingiza) mu kintu kya katodi, ate obusannyalazo buyita mu nkulungo ey’ebweru, nga buwa amaanyi eri ekyuma ekiyungiddwa.
Enzirukanya zino ziraga okutambuza amasannyalaze ga lithium n’okutambula kwa obusannyalazo okukwatagana, nga bino bye bikulu mu kukola kwa bbaatule.
Battery za lithium-ion zimanyiddwa olw’engeri zazo entongole, gamba nga amaanyi amangi, okwefulumya okutono, n’obulamu obw’enzirukanya empanvu. Ebintu bino bibafuula ebirungi ennyo mu nkola awali amaanyi agawangaala ennyo. Ebipimo by’omutindo gw’emirimu ebiwerako bye bikozesebwa okwekenneenya bbaatule za lithium-ion:
Densite y’amasoboza: egera obungi bw’amasoboza agaterekeddwa mu voliyumu oba obuzito obuweereddwa.
Obulamu bw’enzirukanya: Kiraga omuwendo gw’enzirukanya ya chajingi-okufuuwa bbaatule esobola okuyita mu maaso nga obusobozi bwayo bukendeera nnyo.
C-rate: Ennyonnyola omuwendo gwa bbaatule kwe gukuŋŋaanyizibwa oba okufulumizibwa okusinziira ku busobozi bwayo obusinga.
Okulondoola enzirukanya y’omusango n’okufulumya bbaatule za lithium-ion kikulu nnyo okulaba nga ziwangaala n’obukuumi bwazo. Okusasuza ennyo oba okufulumya ennyo kiyinza okuvaako bbaatule okwonooneka, okukendeeza ku busobozi, n’okutuuka ku bulabe bw’obukuumi ng’okudduka okw’ebbugumu. Okulondoola okulungi kuyamba mu kukuuma omulimu omulungi n’okugaziya obulamu bwa bbaatule. eby’okugonjoola eby’omulembe eby’okulondoola nga . DFUN Centralized Battery Monitoring Cloud System ekola kinene nnyo mu kulondoola n’okuddukanya enkola y’okusasula n’okufulumya. Enkola eno ewandiika embeera y’okucaajinga n’okugifulumya mu bujjuvu, ebalila obusobozi obwennyini, era n’ekakasa nti bbaatule okutwalira awamu esigala nga nnungi era nga terimu bulabe okukozesa.
