Chifukwa chiyani mabatire a lithiamu sangathe kugwira ntchito pa kutentha kochepa?

Kodi lithiamu crystal mu batri ya lithiamu ndi chiyani?

Pamene batire ya lithiamu-ion ikuyimbidwa, Li + imachotsedwa ku electrode yabwino ndikugwirizanitsa mu electrode yolakwika;koma pamene zinthu zina zachilendo: monga kusakwanira kwa lithiamu intercalation space mu electrode negative, kukana kwambiri kwa Li + intercalation mu electrode negative, Li + de-intercalates kuchokera ku electrode positive mofulumira kwambiri, koma sangathe intercalated mu kuchuluka chomwecho.Pamene zolakwika monga electrode negative zimachitika, Li + kuti sangathe ophatikizidwa mu elekitirodi zoipa akhoza kupeza ma elekitironi pamwamba pa elekitirodi negative, potero kupanga siliva woyera zitsulo lifiyamu chinthu, amene nthawi zambiri amatchedwa mpweya wa lithiamu. makhiristo.Kusanthula kwa lithiamu sikungochepetsa kugwira ntchito kwa batire, kumafupikitsa kwambiri moyo wanthawi zonse, komanso kumachepetsa kuthamanga kwa batri mwachangu, ndipo kungayambitse zowopsa monga kuyaka ndi kuphulika.Chimodzi mwazifukwa zofunika zomwe zimatsogolera kugwa kwa lithiamu crystallization ndi kutentha kwa batri.Pamene batire imayendetsedwa pa kutentha kochepa, crystallization reaction ya lithiamu precipitation imakhala ndi mlingo wochuluka kuposa momwe lithiamu intercalation process.Elekitirodi yolakwika imakonda kwambiri mvula pansi pa kutentha kochepa.Lithium crystallization reaction.
