Okokuqala, umthamo ongalunganga we-electrode yebhetri ye-lithium ion ayanele Xa i-electrode engafanelekanga inxalenye yebhetri ye-lithium ion inganelanga, ii-athomu ze-lithium apho ukutshaja kwenzeka xa ukutshaja kufakwe kwi-interlayer isakhiwo se-graphite ye-electrode engalunganga, kunye nomphezulu we-electrode embi ihlalutywa. I-crystallization kwibhetri ye-lithium-ion iya kubangela isiphaluka esifutshane. Ngeli xesha, ibhetri ikhutshwe ngokukhawuleza, kuya kubakho ubushushu obukhulu, kutshise i-diaphragm.

Ukushisa okuphezulu kuya kuhlalutya i-electrolyte kwigesi, xa uxinzelelo lukhulu kakhulu, ibhetri iya kuqhuma. Okwesibini, umthamo wokufuma uphezulu kakhulu njengebhetri ye-lithium ion, ukufuma kunokusabela nge-lithium, okukhokelela kwi-lithium oxide, okukhokelela ekulahlekelweni kwamandla ebhetri, ekulula ukubangela ukuba ibhetri ihlawulwe kakhulu ukuvelisa igesi, kwaye i-voltage yohlalutyo lwe-hydraulic iphantsi kakhulu, kulula ukuhlalutya igesi evelisayo xa itshaja, iya kwandisa ibhetri yangaphakathi kunye nebhetri yangaphakathi. izithuba, ibhetri iya kudubula. Okwesithathu, i-short circuit short circuit ibangela ukukhutshwa okukhulu kwangoku, kukho ubushushu obukhulu, ukutshisa i-diaphragm embi, kubangele isiphaluka esifutshane esikhulu, esibangela ukuba i-electrolyte ihlalutye igesi, uxinzelelo lwangaphakathi lukhulu kakhulu, ibhetri iya kuqhuma.

4. Xa ibhetri ye-lithium-ion ihlawuliswa ngokugqithiseleyo, i-lithium yokukhululwa ngokugqithiseleyo kwe-electrode efanelekileyo iya kutshintsha isakhiwo se-electrode efanelekileyo, kwaye i-lithium egqithisileyo ayinakukwazi ukuyifaka kwi-electrode engafanelekanga, kwaye ibangelwa lula ukuba ibangele i-lithium ngokusebenzisa indawo engafanelekanga, kwaye xa i-voltage ifikelela kwi-4.5V okanye ngaphezulu, i-electrolyte iya kuhlalutya inani elikhulu legesi.

Inokubangela ugqabhuko-dubulo kuzo zonke iintlobo. 5. I-short-circuit short circuit yangaphandle inokubangela ukuba i-poly and negative pole impazamo, ngenxa yesiphaluka esifutshane sangaphandle, ukukhutshwa kwebhetri ngoku kuya kwenza ubushushu bebhetri, ubushushu obuphezulu buya kubangela ukuba i-diaphragm ngaphakathi kwebhetri iyancipha okanye yonakalise ngokupheleleyo isiphaluka esifutshane sangaphakathi.

Ke ngoko, yaqhuma. .
