Hariho ubwoko butatu bwingenzi bwabateri ya lithium-ion(li-ion): selile silindrike, selile prismatic selile, na selile pouch.Mu nganda za EV, iterambere ryiza cyane rizenguruka kuri selile na prismatic selile.Mugihe imiterere ya batiri ya silindrike yamenyekanye cyane mumyaka yashize, ibintu byinshi byerekana ko selile prismatic ishobora gufata.

NikiIngirabuzimafatizo

A.ingirabuzimafatizoni selile ifite chimie ifunze mugukomera.Imiterere yurukiramende yemerera gutondeka neza ibice byinshi muri module ya bateri.Hariho ubwoko bubiri bwa selile prismatic: impapuro za electrode imbere mugisanduku (anode, itandukanya, cathode) zirashyizwe hamwe cyangwa zizunguruka kandi zirambuye.

Kubunini bumwe, selile prismatic selile irashobora kurekura ingufu icyarimwe, igatanga imikorere myiza, mugihe selile prismatic selile irimo ingufu nyinshi, itanga igihe kirekire.

Ingirabuzimafatizo zikoreshwa cyane muri sisitemu yo kubika ingufu hamwe n’imodoka zikoresha amashanyarazi.Ingano nini yabo ituma baba abakandida babi kubikoresho bito nka e-gare na terefone.Kubwibyo, birakwiriye cyane kubikorwa byingufu nyinshi.

Utugingo ngengabuzima ni iki

A.ingirabuzimafatizoni selile ifunze muri silinderi ikomeye.Utugingo ngengabuzima ni duto kandi tuzengurutse, bituma bishoboka kubishyira mu bikoresho by'ubunini bwose.Bitandukanye nubundi buryo bwa bateri, imiterere yabyo irinda kubyimba, ibintu bitifuzwa muri bateri aho imyuka iba yegeranye.

Ingirabuzimafatizo ya cylindrical yakoreshejwe bwa mbere muri mudasobwa zigendanwa, zirimo selile ziri hagati ya eshatu na cyenda.Nyuma bamenyekanye cyane mugihe Tesla yabikoresheje mumodoka yambere yamashanyarazi (Roadster na Model S), yarimo selile ziri hagati ya 6.000 na 9000.

Ingirabuzimafatizo nazo zikoreshwa muri e-gare, ibikoresho byubuvuzi, na satelite.Zirakenewe kandi mubushakashatsi bwikirere kubera imiterere yabyo;ubundi buryo bwimikorere bwakagari byahinduwe numuvuduko wikirere.Rover yanyuma yoherejwe kuri Mars, kurugero, ikora ikoresheje selile.Imodoka yo mumashanyarazi ya formula E ikora cyane ikoresha selile imwe na rover muri bateri yabo.

Itandukaniro Rikuru Hagati ya Prismatic na Cylindrical Cells

Imiterere ntabwo aricyo kintu cyonyine gitandukanya selile prismatic na silindrike.Ibindi bitandukanye byingenzi birimo ubunini bwabyo, umubare wamashanyarazi, hamwe nimbaraga zabo.

Ingano

Prismatic selile nini cyane kuruta selile ya silindrike bityo ikaba irimo ingufu nyinshi kuri selile.Gutanga igitekerezo gikabije cyo gutandukanya, selile imwe prismatic irashobora kuba irimo ingufu zingana na selile 20 kugeza 100.Ingano ntoya ya selile ya silindrike bivuze ko ishobora gukoreshwa mubisabwa bisaba imbaraga nke.Nkigisubizo, zikoreshwa kumurongo mugari wa porogaramu.

Kwihuza

Kuberako prismatic selile nini kuruta selile silindrike, selile nkeya zirakenewe kugirango tugere kungufu zingana.Ibi bivuze ko kubunini bumwe, bateri zikoresha selile prismatic zifite amashanyarazi make agomba gukenera.Nibyiza byingenzi kuri selile prismatic kuko hari amahirwe make yo gukora inenge.

Imbaraga

Ingirabuzimafatizo zishobora kubika imbaraga nke ugereranije na selile prismatic, ariko zifite imbaraga nyinshi.Ibi bivuze ko selile ya silindrike ishobora gusohora imbaraga byihuse kuruta selile prismatic.Impamvu nuko bafite amahuza menshi kuri amp-saha (Ah).Nkigisubizo, selile ya silindrike nibyiza kubikorwa byogukora cyane mugihe selile prismatic selile ari nziza mugutezimbere ingufu.

Urugero rwibikorwa bya batiri ikora cyane harimo imodoka yo kwiruka ya Formula E hamwe na kajugujugu ya Ingenuity kuri Mars.Byombi bisaba imikorere ikabije mubidukikije bikabije.

Impamvu ingirabuzimafatizo zishobora kuba zifata

Inganda za EV ziratera imbere byihuse, kandi ntibizwi niba selile prismatic cyangwa selile silindrike izatsinda.Kuri ubu, selile ya silindrike irakwirakwira cyane munganda za EV, ariko hariho impamvu zo gutekereza ko selile prismatic izunguka mubyamamare.

Ubwa mbere, selile prismatic itanga amahirwe yo kugabanya ibiciro mugabanya umubare wintambwe yo gukora.Imiterere yabo ituma bishoboka gukora selile nini, igabanya umubare wamashanyarazi akeneye gusukurwa no gusudwa.

Batteri ya prismatique nayo nuburyo bwiza bwa chimie ya lithium-fer fosifate (LFP), kuvanga ibikoresho bihendutse kandi byoroshye.Bitandukanye na chimisties, bateri ya LFP ikoresha ibikoresho biri hose kwisi.Ntibakenera ibikoresho bidasanzwe kandi bihenze nka nikel na cobalt bitwara igiciro cyubundi bwoko bwakagari hejuru.

Hano hari ibimenyetso bikomeye byerekana ko LFP prismatic selile igaragara.Muri Aziya, abakora EV basanzwe bakoresha bateri ya LiFePO4, ubwoko bwa batiri ya LFP muburyo bwa prismatic.Tesla yavuze kandi ko yatangiye gukoresha bateri za prismatique zakozwe mu Bushinwa ku buryo busanzwe bw’imodoka zayo.

Ubuhanga bwa LFP bufite ingaruka mbi, ariko.Kuri imwe, irimo ingufu nke ugereranije nizindi chimisties zikoreshwa ubu kandi, nkizo, ntizishobora gukoreshwa mumodoka ikora cyane nkimodoka yamashanyarazi ya Formula 1.Byongeye kandi, sisitemu yo gucunga bateri (BMS) ifite ikibazo cyo guhanura urwego rwa bateri.

Urashobora kureba iyi video kugirango umenye byinshi kuriLFPchimie n'impamvu igenda ikundwa.
