1.18650 ibhethri

18650 ibhethri ye-lithium ibhethri elijwayelekile elibekwe ngabakwaSony ukonga imali. U-“18” ukhombisa ububanzi obungu-18mm, u-“65” ukhombisa ubude obungama-65mm, kanti u-“0” ukhombisa ibhethri eliyicylindrical. Kunezinhlobo zezikali kuphela zamabhethri, ezingahlukaniswa zibe amabhethri e-lithium iron phosphate, amabhethri e-lithium cobalt oxide, namabhethri e-lithium ngokusho kolwazi oluhlukile lwe-electrode engalungile.

Ngalowo nyaka, imoto yezemidlalo yakwaTesla yasebenzisa ibhethri ye-lithium cobalt oxide engu-18650, kamuva eyashintshwa yaba ibhethri ledatha le-ternary elenziwe ngokwezifiso i-Panasonic, okungukuthi, ibhethri ledatha ye-nickel-cobalt-aluminium ternary positive. Imodeli-S isebenzisa amabhethri angaphezu kuka-8,000, 1,000 ngaphezu kwe-Roadster, kodwa intengo ishibhe ngo-30%. Iyini i-lithium cobalt oxide? Iyini ibhethri ye-ternary lithium? Ungakwenza kucace! Sawubona, ungakhathazeki, ungafunda, mngani omuhle…

2. Ibhethri ye-ion ye-lithium cobalt

Ibhethri ye-Li-cobalt ion iwuhlobo lwebhethri ye-lithium enesakhiwo esizinzile, isilinganiso somthamo ophezulu kanye nomsebenzi ovelele wokuzwa. Nokho, ukuphepha kwayo kuphansi futhi nezindleko ziphezulu. Kubaluleke kakhulu ekukhiqizeni omakhalekhukhwini, ama-laptops nezinye izinto zikagesi eziphathwayo. I-Tesla iyona kuphela inkampani esebenzisa amabhethri e-lithium cobalt-ion angu-18650 emotweni yayo yokuqala kagesi, i-Roadster.

3. Ternary lithium battery

Ibhethri ye-Ternary lithium ibhethri le-lithium elenziwe nge-lithium nickel cobalt manganese (Li(NiCoMn)O2) idatha ye-electrode eyinegethivu. Ihlobene nebhethri ye-lithium cobalt acid futhi inokuphepha okuphezulu. Ifanele amabhethri amancane. Ukuminyana kwamandla ebhethri le-ternary lithium kuphakeme kakhulu kunebhethri le-lithium iron phosphate, cishe ku-200Wh/kg, okusho ukuthi ibhethri ye-lithium ye-ternary yokwakheka okufanayo inokuphila okude kunebhethri ye-lithium iron phosphate.

I-Sanyo, i-Panasonic, i-Sony, i-LG, i-Samsung nezinye izinhlobo ezinhlanu zamabhethri amakhulu emhlabeni ziye zethula ngokulandelana amabhethri edatha amathathu. Amabhethri anamandla aphansi namandla aphezulu ekhaya naphesheya asebenzisa idatha evumayo kakhulu.

Amamodeli amele: Tesla MODEL S, BAIC Saab EV, EV200, BMW I3, JAC, iEV5, Chery eQ

4. Ibhethri ye-lithium iron phosphate

Ibhethri ye-lithium iron phosphate ibhethri le-lithium eline-lithium iron phosphate njengedatha evumayo. Isici sayo esivelele kakhulu ukuzinza kwe-thermal, okufika kuqala kumabhethri e-lithium ezimoto. Ngakho-ke, isibe esinye sezigaba ezibalulekile zamabhethri emoto kagesi.

Amafutha e-hydrogen

Ama-fuel cell cell asebenzisa ikhemikhali i-hydrogen ukwenza amabhethri agcina amandla. Isimiso esiyisisekelo ukusabela okuhlanekezelwe kwamanzi e-electrolyzed, okunikeza i-hydrogen nomoya-mpilo ku-cathode kanye ne-anode ngokulandelanayo. I-Hydrogen isakazeka ngaphandle ngokusabela kokuhlasela kwe-cathode ne-electrolyte, futhi ama-electron akhululwa ku-anode ngomthwalo wangaphandle, ashiye amanzi nokushisa kuphela. Ukusebenza kahle kokukhiqizwa kwamandla kwamaseli amandla kaphethiloli kungafinyelela ngaphezu kuka-50%, okunqunywa izici zokuguqula zamaseli amandla kaphethiloli. I-fuel power cell iguqula ngokuqondile amandla amakhemikhali abe amandla kagesi, ngaphandle kwesidingo sokuguqulwa okuphakathi kwamandla ashisayo namandla emishini (amajeneretha).

Manje, imoto yokuqala yakwaToyota ekhiqizwa ngobuningi i-hydrogen fuel cell sedan, i-Mirai, izokwethulwa eJapan ngoDisemba 15, nenani elilinganiselwa ku-723,000 yen, amandla angu-114 kilowatts, kanye nebanga lokuhamba ngomkhumbi elingamakhilomitha angama-650. Amanye amamodeli amele: iHonda FCV concept car, egijima i-b-class fuel cell sedan
