Umehluko phakathi kwebhethri nebhethri ye-lithium: [Longxingtonng lithium battery]

1. Izingxenye ezihlukene zokushaja nokukhipha:

(1) Ibhethri linenkumbulo futhi alikwazi ukushajwa noma ukushajwa nganoma yisiphi isikhathi; kukhona into engathi sína yokuzikhipha, futhi ibhethri kulula ukuyikhipha ngemva kokushiywa isikhathi esithile; izinga lokukhipha lincane, futhi alikwazi ukukhishwa ngomsinga omkhulu isikhathi eside.

(2) Ibhethri le-lithium alinawo umphumela wenkumbulo, ibhethri lingashajwa futhi likhishwe nganoma yisiphi isikhathi, ukuzikhipha kwebhethri kuphansi, ukuzikhipha kwanyanga zonke kungaphansi kwe-1%, ibhethri ingagcinwa isikhathi eside; amandla anamandla, angashajwa ngokushesha futhi akhululwe, futhi angashajwa ngaphezu kuka-80% ngemizuzu engu-20 , Amandla angakhishwa ngemizuzu engu-15.

2. Ukubekezelela izinga lokushisa okuhlukile:

(1) Izinga lokushisa lokusebenza kwebhethri ngokuvamile lidingeka libe phakathi kuka-20°C no-25°C. Uma ingaphansi kuka-15 ° C, amandla ayo okuphuma azokwehla. Njalo ngo-1°C ukwehla kwezinga lokushisa, amandla ayo azokwehla ngo-1%, futhi izinga lokushisa liphezulu kakhulu (ngaphezu kuka-30°C) Isikhathi sokuphila sayo sizofinyezwa kakhulu.

(2) Izinga lokushisa elivamile lokusebenza lamabhethri e-lithium lingu-20-60 degrees Celsius, kodwa ngokuvamile lapho izinga lokushisa lingaphansi kuka-0 degrees Celsius, ukusebenza kwamabhethri e-lithium kuzokwehla, futhi amandla okukhipha azoncishiswa ngokufanayo. Ngakho-ke, izinga lokushisa lokusebenza ekusebenzeni okugcwele kwamabhethri e-lithium ngokuvamile li-0 ~ 40°C. Izinga lokushisa lamabhethri e-lithium adingwa izindawo ezithile ezikhethekile lihlukile, futhi amanye angasebenza ngokujwayelekile endaweni engamakhulu amadigri Celsius.

3. Ifomula yokusabela kwamakhemikhali ihlukile ngesikhathi sokukhishwa:

(1) Uma ibhethri likhishwa: negative Pb(s)-2e-+SO42-(aq)=PbSO4(s).

(2) Ukusabela kokushajwa kwebhethri le-lithium: Li+MnO2=LiMnO2.
