Kunezinhlobo ezintathu eziyinhloko zeamabhethri e-lithium-ion(i-li-ion): amaseli angama-cylindrical, amaseli e-prismatic, namaseli esikhwama.Embonini ye-EV, intuthuko ethembisa kakhulu izungeza amaseli angama-cylindrical nama-prismatic.Ngenkathi ifomethi yebhethri eyicylindrical ibidume kakhulu eminyakeni yakamuva, izici ezimbalwa ziphakamisa ukuthi amaseli e-prismatic angase athathe izintambo.

Yini iziAmaseli Prismatic

Ai-prismatic celliyiseli ikhemikhali yalo evalelwe kukesi eqinile.Umumo wayo ongunxande uvumela ukunqwabelanisa kahle amayunithi amaningi kumojuli yebhethri.Kunezinhlobo ezimbili zamaseli e-prismatic: amashidi e-electrode ngaphakathi kwe-casing (i-anode, isihlukanisi, i-cathode) ayapakishwa noma agoqwe futhi abekwe isicaba.

Ngevolumu efanayo, amaseli e-prismatic astakiwe angakhulula amandla engeziwe ngesikhathi esisodwa, anikeze ukusebenza okungcono, kuyilapho amaseli e-prismatic ayisicaba aqukethe amandla engeziwe, anikeza ukuqina okwengeziwe.

Amaseli ePrismatic asetshenziswa kakhulu ezinhlelweni zokugcina amandla nasezimotweni zikagesi.Usayizi wabo omkhulu ubenza babe abantu abangalungile kumadivayisi amancane njengamabhayisikili e-e namaselula.Ngakho-ke, zifaneleka kangcono izinhlelo zokusebenza ezidinga amandla.

Ayini Amaseli E-Cylindrical

Ai-cylindrical celliyiseli elivalwe ethini le-cylinder eliqinile.Amaseli angama-cylindrical mancane futhi ayindilinga, okwenza kube nokwenzeka ukunqwabelana kumishini yawo wonke amasayizi.Ngokungafani namanye amafomethi ebhethri, ukwakheka kwawo kuvimbela ukuvuvukala, into engafuneki kumabhethri lapho amagesi anqwabelana ku-casing.

Amaseli angama-cylindrical aqale ukusetshenziswa kuma-laptops, aqukethe phakathi kwamaseli amathathu nayisishiyagalolunye.Babe sebethola ukuthandwa lapho uTesla ebasebenzisa ezimotweni zakhe zokuqala zikagesi (i-Roadster kanye ne-Model S), equkethe amaseli aphakathi kuka-6,000 no-9,000.

Amaseli angama-cylindrical abuye asetshenziswe kuma-e-bikes, imishini yezokwelapha, namasathelayithi.Zibalulekile futhi ekuhloleni indawo ngenxa yokuma kwazo;amanye amafomethi amaseli azokhutshazwa ukucindezela komkhathi.I-Rover yokugcina ethunyelwe ku-Mars, ngokwesibonelo, isebenza kusetshenziswa amaseli angama-cylindrical.Izimoto zomjaho zikagesi ze-Formula E ezisebenza kahle kakhulu zisebenzisa amaseli afana nse ne-rover ebhethrini lawo.

Umehluko Oyinhloko Phakathi Kwamaseli E-Prismatic kanye Nama-Cylindrical

Ukuma akuyona into kuphela ehlukanisa amaseli e-prismatic kanye ne-cylindrical.Omunye umehluko obalulekile uhlanganisa usayizi wawo, inani lokuxhunywa kukagesi, kanye nokuphuma kwawo kwamandla.

Usayizi

Amaseli ePrismatic makhulu kakhulu kunamaseli angama-cylindrical ngakho aqukethe amandla engeziwe ngeseli ngalinye.Ukuze unikeze umbono onzima womehluko, iseli elilodwa le-prismatic lingaqukatha inani lamandla elilingana namaseli angama-cylindrical angama-20 kuya kwayi-100.Usayizi omncane wamaseli ayi-cylindrical usho ukuthi angasetshenziselwa izinhlelo zokusebenza ezidinga amandla amancane.Ngenxa yalokho, zisetshenziselwa uhla olubanzi lwezinhlelo zokusebenza.

Ukuxhumana

Ngenxa yokuthi amaseli e-prismatic makhulu kunamaseli angama-cylindrical, amaseli ambalwa ayadingeka ukuze kuzuzwe inani elifanayo lamandla.Lokhu kusho ukuthi ngevolumu efanayo, amabhethri asebenzisa amaseli e-prismatic anokuxhumana okumbalwa kukagesi okudingeka ashiselwe.Lokhu kuyinzuzo enkulu kumaseli e-prismatic ngoba mancane amathuba okukhiqiza amaphutha.

Amandla

Amaseli angama-cylindrical angase agcine amandla amancane kunamaseli e-prismatic, kodwa anamandla amaningi.Lokhu kusho ukuthi amaseli angama-cylindrical angakhipha amandla awo ngokushesha kunamaseli e-prismatic.Isizathu siwukuthi banokuxhumana okuningi ngehora ngalinye (Ah).Ngenxa yalokho, amaseli angama-cylindrical alungele izinhlelo zokusebenza ezisebenza kahle kanti amaseli e-prismatic alungele ukwandisa ukusebenza kahle kwamandla.

Isibonelo sezinhlelo zokusebenza zebhethri ezisebenza kahle zibandakanya izimoto zomjaho ze-Formula E kanye nendiza enophephela emhlane ye-Ingenuity ku-Mars.Kokubili kudinga ukusebenza okwedlulele ezindaweni ezimbi kakhulu.

Kungani Amaseli E-Prismatic Angase Athathe

Imboni ye-EV ishintsha ngokushesha, futhi akuqiniseki ukuthi amaseli e-prismatic noma amaseli angama-cylindrical azophumelela.Okwamanje, amangqamuzana angama-cylindrical asakazeke kakhulu embonini ye-EV, kodwa kunezizathu zokucabanga ukuthi amaseli e-prismatic azothola ukuthandwa.

Okokuqala, amaseli e-prismatic anikeza ithuba lokwehlisa izindleko ngokunciphisa inani lezinyathelo zokukhiqiza.Ukuma kwawo kwenza kube nokwenzeka ukukhiqiza amaseli amakhulu, okunciphisa inani lokuxhunywa kukagesi okudingeka ahlanzwe futhi ashiselwe.

Amabhethri e-Prismatic futhi ayifomethi efanelekile yekhemistri ye-lithium-iron phosphate (LFP), ingxube yezinto ezishibhile futhi ezifinyeleleka kalula.Ngokungafani namanye amakhemikhali, amabhethri e-LFP asebenzisa izinsiza ezikuyo yonke indawo emhlabeni.Azidingi izinto ezingavamile nezimba eqolo njenge-nickel ne-cobalt eziqhubekisela phambili izindleko zezinye izinhlobo zamaseli.

Kunezimpawu eziqinile zokuthi amaseli e-LFP prismatic ayavela.E-Asia, abakhiqizi be-EV sebevele basebenzisa amabhethri e-LiFePO4, uhlobo lwebhethri ye-LFP ngefomethi ye-prismatic.UTesla uphinde waveza ukuthi isiqalile ukusebenzisa amabhethri e-prismatic akhiqizwa eChina ezinguqulweni ezijwayelekile zezimoto zayo.

Ikhemikhali ye-LFP inokwehla okubalulekile, nokho.Kokunye, iqukethe amandla amancane kunamanye amakhemikhali asetshenziswayo njengamanje, futhi ngenxa yalokho, ayikwazi ukusetshenziselwa izimoto ezisebenza kahle njengezimoto zikagesi ze-Formula 1.Ukwengeza, amasistimu okuphatha ibhethri (BMS) anenkinga yokubikezela izinga lokushajwa kwebhethri.

Ungabuka le vidiyo ukuze ufunde kabanzi mayelana nalokhuI-LFPi-chemistry nokuthi kungani ithola ukuthandwa.
