Ukusebenza kobushushu obuphantsi

Enye yezona mpawu ziphambili zezi bhetri kukusebenza kwazo kakuhle kwiindawo ezinobushushu obuphantsi. Nangona iibhetri ze-lithium-ion zihlala zijongene nemingeni kwiimeko ezibandayo, iibhetri ze-LiFePO₄ zesikhwama sobushushu obuphantsi ziye zayilwa ukunciphisa ezi ngxaki. Iifomyula ezikhethekileyo ze-electrolyte kunye noyilo lweeseli zinceda ukugcina ukuhanjiswa kwee-ion, ukuqinisekisa ukuba ibhetri isenokubonelela ngamandla afanelekileyo nokuba kumaqondo obushushu angaphantsi kwe-zero. Oku kuzenza zilungele ukusetyenziswa kwiindawo ezibandayo, njengezixhobo zokujonga ezikude kunye neenkqubo zokugcina izinto ezibandayo.

Iibhetri zePrismatic Lithium Iron Phosphate

Iingenelo zeZakhiwo

Iibhetri zePrismatic lithium iron phosphate zinebhokisi eqinileyo, emile okwengxande. Olu lwakhiwo lubonelela ngamandla oomatshini aphuculweyo, lukhusela izinto zangaphakathi ekonakalisweni ngokwasemzimbeni. Lukwayenza lula inkqubo yokudibanisa kwiipakethe zebhetri, njengoko imo efanayo ivumela ukulungelelaniswa kunye nokunxibelelana kweeseli ezininzi ngokulula.

Ukusebenza kwiimeko ezinzima

Ukongeza ekuqineni kwazo koomatshini, iibhetri ze-prismatic LiFePO₄ zibonisa ukusebenza kakuhle kwiimeko ezahlukeneyo zendalo, kuquka iimeko zobushushu obuphantsi. Uyilo lwazo lunceda ukusasazwa kobushushu okungcono kunye nolawulo lobushushu, nto leyo ibalulekileyo ekugcineni ukusebenza kwebhetri kwiindawo ezibandayo nezishushu ngokufanayo. Kwiimeko zobushushu obuphantsi, uyilo olucwangcisiweyo lunceda ekusasazeni ngokulinganayo i-electrolyte kunye nokugcina intshukumo ye-ion ehambelanayo ngaphakathi kwiseli.

Izicelo

Izithuthi zombane
