Ho na le mefuta e meraro ea mantlha ealibeteri tsa lithium-ion(li-ion): lisele tsa cylindrical, lisele tsa prismatic, le lisele tsa mokotla.Ka indasteri ea EV, tsoelo-pele e tšepisang ka ho fetisisa e pota-potile lisele tsa cylindrical le tsa prismatic.Le hoja mokhoa oa betri oa cylindrical o ntse o tumme ka ho fetisisa lilemong tsa morao tjena, lintlha tse 'maloa li fana ka maikutlo a hore lisele tsa prismatic li ka nka sebaka.

Ke Eng?Lisele tsa Prismatic

Aprismatic cellke sele eo k'hemik'hale ea eona e kentsoeng ka mokotleng o thata.Sebopeho sa eona sa khutlonnetsepa se u lumella ho bokella likarolo tse ngata ka har'a mojule oa betri.Ho na le mefuta e 'meli ea lisele tsa prismatic: maqephe a electrode ka hare ho casing (anode, separator, cathode) a kenngoa kapa a phuthoa ebe a batalatsoa.

Bakeng sa molumo o tšoanang, lisele tsa prismatic tse pakiloeng li ka lokolla matla a mangata ka nako e le 'ngoe, li fana ka tshebetso e ntlafetseng, athe lisele tse bataletseng tsa prismatic li na le matla a mangata, a fanang ka nako e telele.

Lisele tsa prismatic li sebelisoa haholo lits'ebetsong tsa polokelo ea matla le likoloi tsa motlakase.Boholo ba bona bo boholo bo etsa hore e be batho ba sa sebetseng hantle bakeng sa lisebelisoa tse nyane joalo ka libaesekele tsa elektroniki le mehala ea thekeng.Ka hona, li loketse hamolemo bakeng sa lisebelisoa tse sebelisang matla.

Lisele tsa Cylindrical ke Eng

Acylindrical cellke sele e kentsoeng ka har'a moqomo o thata.Lisele tsa cylindrical li nyenyane ebile li pota-potile, li etsa hore ho khonehe ho li bokella ka lisebelisoa tsa boholo bohle.Ho fapana le mefuta e meng ea betri, sebopeho sa tsona se thibela ho ruruha, ntho e sa batleheng ka har'a libeteri moo likhase li bokellanang ka har'a casing.

Lisele tsa cylindrical li qalile ho sebelisoa ka har'a lilaptop, tse neng li e-na le lisele tse pakeng tsa tse tharo le tse robong.Eaba ba fumana botumo ha Tesla a ba sebelisa likoloing tsa eona tsa pele tsa motlakase (Roadster le Model S), tse neng li e-na le lisele tse pakeng tsa 6,000 le 9,000.

Lisele tsa cylindrical li boetse li sebelisoa ho e-baesekele, lisebelisoa tsa bongaka le lisathelaete.Li boetse li bohlokoa ho hlahloba sebaka ka lebaka la sebōpeho sa tsona;mefuta e meng ea lisele e ne e tla holofatsoa ke khatello ea sepakapaka.Ka mohlala, Rover ea ho qetela e rometsoeng ho Mars, e sebetsa ka lisele tsa cylindrical.Likoloi tsa lebelo la motlakase tsa Formula E tse sebetsang hantle haholo li sebelisa lisele tse ts'oanang hantle le rover ka betri ea tsona.

Phapang e ka Sehloohong Pakeng tsa Lisele tsa Prismatic le Cylindrical

Sebopeho hase eona feela ntho e khethollang lisele tsa prismatic le cylindrical.Liphapang tse ling tsa bohlokoa li kenyelletsa boholo ba tsona, palo ea likhokahano tsa motlakase, le matla a tsona.

Boholo

Lisele tsa prismatic li kholo haholo ho feta lisele tsa cylindrical, ka hona li na le matla a mangata ka sele.Ho fana ka maikutlo a hlakileng a phapang, sele e le 'ngoe ea prismatic e ka ba le matla a lekanang le lisele tsa cylindrical tse 20 ho isa ho tse 100.Lisele tse nyane tsa cylindrical li bolela hore li ka sebelisoa bakeng sa lits'ebetso tse hlokang matla a fokolang.Ka lebaka leo, li sebelisoa bakeng sa mefuta e mengata ea lisebelisoa.

Lihokelo

Hobane lisele tsa prismatic li kholo ho feta lisele tsa cylindrical, lisele tse fokolang li hlokahala ho fumana matla a lekanang.Sena se bolela hore bakeng sa molumo o tšoanang, libeteri tse sebelisang lisele tsa prismatic li na le likhokahano tse fokolang tsa motlakase tse hlokang ho chesetsoa.Ena ke monyetla o moholo bakeng sa lisele tsa prismatic hobane ho na le menyetla e fokolang ea ho etsa liphoso.

Lisele tsa cylindrical li ka boloka matla a fokolang ho feta lisele tsa prismatic, empa li na le matla a mangata.Sena se bolela hore lisele tsa cylindrical li ka ntša matla a tsona ka potlako ho feta lisele tsa prismatic.Lebaka ke hore ba na le likhokahano tse ngata ka hora (Ah).Ka lebaka leo, lisele tsa cylindrical li loketse lits'ebetso tse sebetsang hantle athe lisele tsa prismatic li loketse ho ntlafatsa matla a matla.

Mohlala oa lits'ebetso tsa betri tse sebetsang hantle haholo li kenyelletsa likoloi tsa lebelo la Formula E le helikopta ea Ingenuity ho Mars.Ka bobeli li hloka ts'ebetso e feteletseng maemong a feteletseng.

Hobaneng ha Lisele tsa Prismatic li ka 'na tsa nka

Indasteri ea EV e fetoha ka potlako, 'me ha ho na bonnete ba hore na lisele tsa prismatic kapa lisele tsa cylindrical li tla ba teng.Hona joale, lisele tsa cylindrical li atile haholo indastering ea EV, empa ho na le mabaka a ho nahana hore lisele tsa prismatic li tla fumana botumo.

Ntlha ea pele, lisele tsa prismatic li fana ka monyetla oa ho theola litšenyehelo ka ho fokotsa palo ea mehato ea tlhahiso.Sebopeho sa bona se etsa hore ho khonehe ho etsa lisele tse kholoanyane, tse fokotsang palo ea likhokahano tsa motlakase tse hlokang ho hloekisoa le ho chesetsoa.

Libetri tsa prismatic le tsona ke sebopeho se loketseng bakeng sa k'hemistri ea lithium-iron phosphate (LFP), motsoako oa thepa e theko e tlase ebile e fumaneha habonolo.Ho fapana le lik'hemik'hale tse ling, libeteri tsa LFP li sebelisa lisebelisoa tse teng hohle lefatšeng.Ha li hloke lisebelisoa tse sa tloaelehang le tse theko e boima joalo ka nickel le cobalt tse tsamaisang litšenyehelo tsa mefuta e meng ea lisele holimo.

Ho na le matšoao a matla a hore lisele tsa prismatic tsa LFP lia hlaha.Asia, baetsi ba EV ba se ba ntse ba sebelisa libeteri tsa LiFePO4, mofuta oa betri ea LFP ka mokhoa oa prismatic.Tesla o boetse a re e se e qalile ho sebelisa libeteri tsa prismatic tse entsoeng Chaena bakeng sa mefuta e tloaelehileng ea likoloi tsa eona.
