Kunezinhlobo ezintathu eziyinhloko ze-amabhethri e-lithium-ion(i-li-ion): amaseli ayisilinda, amaseli e-prismatic, namaseli esikhwama. Embonini ye-EV, intuthuko ethembisayo kakhulu ijikeleza amaseli ayisilinda kanye ne-prismatic. Nakuba ifomethi yebhethri eliyisilinda ibilokhu ithandwa kakhulu eminyakeni yamuva nje, izici eziningana zisikisela ukuthi amaseli e-prismatic angase athathe izintambo.

Yini iziAmaseli e-Prismatic

Aiseli le-prismaticiyiseli elinokwakheka kwamakhemikhali okuvalelwe esikhaleni esiqinile. Ukuma kwalo okungunxande kuvumela ukufaka amayunithi amaningi ngendlela ephumelelayo kumojuli yebhethri. Kunezinhlobo ezimbili zamaseli e-prismatic: amashidi e-electrode ngaphakathi kwesivalo (i-anode, i-separator, i-cathode) ahlanganiswa noma asongwe futhi acwebezelwe.

Ngomthamo ofanayo, amaseli e-prismatic ahlanganisiwe angakhipha amandla amaningi ngesikhathi esisodwa, anikeze ukusebenza okungcono, kuyilapho amaseli e-prismatic ayisicaba aqukethe amandla amaningi, anikeza ukuqina okwengeziwe.

Amaseli e-Prismatic asetshenziswa kakhulu ezinhlelweni zokugcina amandla kanye nasezimotweni zikagesi. Ubukhulu bawo obukhulu buwenza abe ngamadivayisi amabi njengamabhayisikili e-elekthronikhi kanye namaselula. Ngakho-ke, afaneleka kangcono ezinhlelweni ezisebenzisa amandla amaningi.

Ayini Amaseli E-Cylindrical

Aiseli eliyindilingaiyiseli elivalelwe ethini eliqinile lesilinda. Amaseli ayisilinda mancane futhi ayindilinga, okwenza kube nokwenzeka ukuwafaka kumadivayisi awo wonke amasayizi. Ngokungafani nezinye izinhlobo zebhethri, ukuma kwawo kuvimbela ukuvuvukala, into engathandeki emabhethri lapho amagesi eqongelela khona ekhasejini.

Amaseli e-cylindrical aqala ukusetshenziswa kuma-laptop, ayenamaseli aphakathi kwamathathu nayisishiyagalolunye. Abe esethola ukuthandwa lapho iTesla iwasebenzisa ezimotweni zayo zokuqala zikagesi (iRoadster kanye neModel S), ezazinamaseli aphakathi kuka-6,000 no-9,000.

Amaseli e-cylindrical asetshenziswa futhi kuma-e-bikes, kumadivayisi ezokwelapha, kanye nama-satellite. Abalulekile nasekuhloleni isikhala ngenxa yesimo sawo; ezinye izinhlobo zamaseli zizophazamiseka ngenxa yokucindezela komoya. I-Rover yokugcina ethunyelwe ku-Mars, isibonelo, isebenza ngamaseli e-cylindrical. Izimoto zomjaho kagesi ze-Formula E ezisebenza kahle kakhulu zisebenzisa amaseli afanayo ne-rover ebhethrini lazo.

Umehluko Omkhulu Phakathi Kwamaseli E-Prismatic Ne-Cylindrical

Isimo akuyona yodwa into ehlukanisa amaseli e-prismatic nama-cylindrical. Eminye imehluko ebalulekile ihlanganisa usayizi wawo, inani lokuxhumeka kukagesi, kanye nokukhishwa kwamandla awo.

Usayizi

Amaseli e-Prismatic makhulu kakhulu kunamaseli ayisilinda ngakho-ke aqukethe amandla amaningi ngeseli ngalinye. Ukuze kunikezwe umbono oqondile womehluko, iseli elilodwa le-prismatic lingaqukatha inani elifanayo lamandla namaseli angamasilinda angu-20 kuya kwangu-100. Ubukhulu obuncane bamaseli asilinda busho ukuthi angasetshenziswa ezinhlelweni zokusebenza ezidinga amandla amancane. Ngenxa yalokho, asetshenziselwa uhla olubanzi lwezinhlelo zokusebenza.

Ukuxhumana

Ngenxa yokuthi amaseli e-prismatic makhulu kunamaseli ayisilinda, kudingeka amaseli ambalwa ukuze kufezwe inani elifanayo lamandla. Lokhu kusho ukuthi ngevolumu efanayo, amabhethri asebenzisa amaseli e-prismatic anokuxhumana kukagesi okuncane okudingeka kuhlanganiswe. Lokhu kuyinzuzo enkulu kumaseli e-prismatic ngoba mancane amathuba okukhiqiza amaphutha.

Amandla

Amaseli e-cylindrical angagcina amandla amancane kunamaseli e-prismatic, kodwa anamandla amaningi. Lokhu kusho ukuthi amaseli e-cylindrical angakhipha amandla awo ngokushesha kunamaseli e-prismatic. Isizathu ukuthi anokuxhumana okwengeziwe nge-amp-hour (Ah). Ngenxa yalokho, amaseli e-cylindrical afanele ukusetshenziswa okuphezulu kanti amaseli e-prismatic afaneleka kakhulu ukuthuthukisa ukusebenza kahle kwamandla.

Isibonelo sezinhlelo zokusebenza zebhethri ezisebenza kahle kakhulu zifaka phakathi izimoto zomjaho zeFormula E kanye nendiza enophephela emhlane i-Ingenuity eMars. Zombili zidinga ukusebenza okukhulu ezindaweni ezibucayi kakhulu.

Kungani Amaseli e-Prismatic Angase Athathe Izintambo

Imboni ye-EV ithuthuka ngokushesha, futhi akuqiniseki ukuthi amaseli e-prismatic noma amaseli e-cylindrical azonqoba yini. Okwamanje, amaseli e-cylindrical asakazeke kakhulu embonini ye-EV, kodwa kunezizathu zokucabanga ukuthi amaseli e-prismatic azothandwa kakhulu.

Okokuqala, amaseli e-prismatic anikeza ithuba lokunciphisa izindleko ngokunciphisa inani lezinyathelo zokukhiqiza. Ifomethi yawo yenza kube nokwenzeka ukukhiqiza amaseli amakhulu, okunciphisa inani lokuxhumeka kukagesi okudingeka kuhlanzwe futhi kushiselwe.

Amabhethri e-Prismatic nawo ayifomethi efanelekile yekhemistri ye-lithium-iron phosphate (LFP), ingxube yezinto ezishibhile futhi ezitholakala kalula. Ngokungafani nezinye izikhungo zamakhemikhali, amabhethri e-LFP asebenzisa izinsiza ezikhona yonke indawo emhlabeni. Awadingi izinto ezingavamile nezibizayo njenge-nickel ne-cobalt ezinyusa izindleko zezinye izinhlobo zamaseli.

Kunezibonakaliso ezinamandla zokuthi amaseli e-LFP prismatic ayavela. E-Asia, abakhiqizi be-EV sebevele basebenzisa amabhethri e-LiFePO4, uhlobo lwebhethri le-LFP ngefomethi ye-prismatic. I-Tesla iphinde yathi isiqalile ukusebenzisa amabhethri e-prismatic akhiqizwa eShayina ngezinguqulo ezijwayelekile zezimoto zayo.

I-chemistry ye-LFP inezinkinga ezibalulekile, nokho. Okokuqala, iqukethe amandla amancane kunezinye izinhlobo zamakhemikhali ezisetshenziswa njengamanje futhi, ngenxa yalokho, ayikwazi ukusetshenziselwa izimoto ezisebenza kahle njengezimoto zikagesi ze-Formula 1. Ngaphezu kwalokho, izinhlelo zokuphatha amabhethri (i-BMS) zinobunzima bokubikezela izinga lokushaja kwebhethri.

Ungabuka le vidiyo ukuze ufunde kabanzi mayelanaI-LFPikhemistri nokuthi kungani ithandwa kakhulu.
