Ukukhishwa kwe-overdish kuya ku-zero voltage test:
I-STL18650 (1100mAh) ibhethri lamandla e-lithium iron phosphate yasetshenziselwa ukukhipha ku-zero voltage test.Izimo zokuhlola: 1100mAh STL18650 ibhethri ishajwe ngokugcwele ngenani lokushaja elingu-0.5C, bese likhishwa kuvoltheji yebhethri engu-0C ngesilinganiso sokuphuma esingu-1.0C.Bese uhlukanisa amabhethri abekwe ku-0V abe ngamaqembu amabili: iqembu elilodwa ligcinwa izinsuku ezingu-7, kanti elinye iqembu ligcinwa izinsuku ezingu-30;ngemva kokuphelelwa yisikhathi kwesitoreji, ishajwa ngokugcwele ngenani lokushaja elingu-0.5C, bese ikhishwa ngo-1.0C.Ekugcineni, umehluko phakathi kwezikhathi ezimbili zokugcina zero-voltage uyaqhathaniswa.
Umphumela wokuhlolwa ukuthi ngemva kwezinsuku ezingu-7 zokugcina i-voltage engu-zero, ibhethri ayinakho ukuvuza, ukusebenza kahle, futhi amandla angu-100%;ngemva kwezinsuku ezingu-30 zokugcina, akukho ukuvuza, ukusebenza kahle, futhi umthamo 98%;ngemva kwezinsuku ezingu-30 zokugcina, ibhethri lingaphansi kwemijikelezo engu-3 yokushaja, Umthamo ubuyele ku-100%.
Lokhu kuhlola kubonisa ukuthi noma ngabe ibhethri ye-lithium iron phosphate ikhishwa ngokweqile (ngisho naku-0V) futhi igcinwe isikhathi esithile, ibhethri ngeke livuze noma lonakaliswe.Lesi isici ezinye izinhlobo zamabhethri e-lithium-ion ezingenaso.
