Isingeniso

Ulishaja Kanjani Ngokuphephile Ibhethri Le-LiFePO4? Amabhethri e-LiFePO4 athole ukunakwa okubalulekile ngenxa yokuphepha kwawo okuphezulu, impilo yomjikelezo omude, kanye nokuminyana kwamandla aphezulu. Lesi sihloko sihlose ukukunikeza umhlahlandlela ophelele wokuthi ungashaja kanjani amabhethri e-LiFePO4 ngokuphepha nangempumelelo ukuze uqinisekise ukusebenza kahle nokuphila isikhathi eside.

Iyini i-LiFePO4?

Amabhethri e-LiFePO4 akhiwe nge-lithium (Li), insimbi (Fe), i-phosphorus (P), ne-oxygen (O). Lokhu kwakheka kwamakhemikhali kubanikeza ukuphepha okuphezulu nokuzinza, ikakhulukazi ngaphansi kwamazinga okushisa aphezulu noma izimo zokushaja ngokweqile.

Izinzuzo LiFePO4 Amabhethri

Amabhethri e-LiFePO4 athandwa ngenxa yokuphepha kwawo okuphezulu, impilo yomjikelezo omude (imvamisa idlula imijikelezo ye-2000), ukuminyana kwamandla aphezulu, kanye nobungane bemvelo. Uma kuqhathaniswa namanye amabhethri e-lithium-ion, amabhethri e-LiFePO4 anezinga eliphansi lokuzikhipha futhi adinga ukulungiswa okuncane.

Izindlela zokushaja zamabhethri e-LiFePO4
