Yintoni umahluko phakathi kweebhetri zeLiFePO₄ kunye neNCM?

Iibhetri zeLithium-ion ziye zabaluleka kakhulu ekunikezeni amandla kwizixhobo zanamhlanje, izithuthi zombane, kunye neenkqubo zokugcina amandla. Phakathi kweekhemikhali ezininzi zeLithium-ion ezikhoyo namhlanje, ezimbini zezona zisetyenziswa kakhulu ziibhetri zeLiFePO₄ (Lithium Iron Phosphate) kunye neebhetri zeNCM (Nickel Cobalt Manganese). Uhlobo ngalunye luneempawu ezizodwa, iingenelo, kunye nokusetyenziswa okuzenza zilungele iimeko ezahlukeneyo zokusetyenziswa.

Iibhetri zeLiFePO₄, ezaziwa ngokuba ziibhetri ze-LFP, zaziwa ngokuzinza kwazo okuhle kakhulu kubushushu nakwikhemikhali. Zinobomi obude bomjikelo, zihlala zifikelela kwimijikelo engaphezu kwama-2000, kwaye zibonelela ngeempawu zokhuseleko eziqinileyo, ezifana nokuchasana nobushushu obugqithisileyo kunye nomngcipheko omncinci wokubaleka kobushushu okanye umlilo. Ukongeza, zisebenza kakuhle phantsi kwamaqondo obushushu aphezulu kwaye zigcina i-voltage ezinzileyo ngexesha lokukhupha. Nangona kunjalo, uxinano lwamandla azo luphantsi kuneebhetri ze-NCM, oko kuthetha ukuba zigcina amandla amancinci ngobukhulu okanye ubunzima obufanayo. Oku kuzenza zingalungelanga ukusetyenziswa apho indawo kunye nobunzima zibalulekile.

Kwelinye icala, Iibhetri ze-NCM—yenziwe nge-nickel, i-cobalt, kunye ne-manganese—inika amandla amaninzi kunye namandla athile ngakumbi. Oku kuyenza ifaneleke ngakumbi kwiimoto zombane (ii-EV), apho umgama omde wokuqhuba kunye nobukhulu bebhetri encinci kubalulekile. Iibhetri ze-NCM zinokubonelela ngokusebenza okuqinileyo ngokubhekiselele ekukhawuleziseni kunye nomphumo ophezulu wamandla. Nangona kunjalo, zinobomi obufutshane bomjikelo xa kuthelekiswa ne-LiFePO₄, zihlala ziqala kwi-1000 ukuya kwi-1500 cycles. Ukongeza, ubukho be-cobalt buphakamisa iinkxalabo zokusingqongileyo kunye nokuziphatha, njengoko inkqubo yayo yokwemba ifuna izixhobo ezininzi kwaye idla ngokuphikiswana.

Ngokuphathelele iindleko, iibhetri zeLiFePO₄ zihlala zibiza kancinci kwaye zinobuhlobo nokusingqongileyo, ngelixa iibhetri zeNCM, nangona zibiza kakhulu, zibonelela ngokusebenza okungcono ngokwemveliso yamandla. Ukukhetha phakathi kwezi zimbini kuxhomekeke kakhulu kwisicelo: ILiFePO₄ ikhethwa kakhulu kwiindawo zokugcina amandla ezisisigxina kunye nezithuthi zombane ezikhawulezayo, ngelixa iNCM ikhethwa kakhulu kwii-EV ezisebenza kakhulu kunye nee-elektroniki eziphathwayo ezifuna imithombo yamandla emincinci, enamandla aphezulu.

Ukuqukumbela, zombini iibhetri zeLiFePO₄ kunye neNCM zinamandla kunye nobuthathaka bazo. Isigqibo phakathi kwazo kufuneka sisekelwe kukhuseleko, iimfuno zamandla, uhlahlo lwabiwo-mali, kunye nempembelelo yokusingqongileyo.
