Kutshanje, kuye kwakho iingxelo ezininzi malunga nokuqhuma kwebhetri yefowuni yeselula, okwabangela ukuba abantu baqwalasele kunye nokungakhululeki. Ngoko kutheni ifowuni ephathwayo iqhuma? Ingaba inkulu kangakanani? Ndiyiphepha njani le meko? Xa kuthelekiswa nobunye ubuchwephesha bebhetri, ibhetri ye-lithium-ion ikhaphukhaphu, inexabiso eliphantsi, kwaye noxinano lwamandla luphezulu. Kuye kwaba yindlela ephambili yeebhetri ezitshajwayo, kuzo zonke izinto ezivela kwiselula ukuya kwii-laptops ekusebenziseni iibhetri ze-lithium ion.

Kodwa le bhetri inengxaki, kwezinye iimeko ezinzima, inokudubula ukuqhuma. Isizathu sokuba ibhetri ye-lithium-ion iya kuba nokuqhuma, okuyintlekele ebizwa ngokuba yinkqubo "ye-thermal out-control". Enyanisweni, "i-thermal out-of control" yinkqubo yomjikelo wempendulo yamandla: ubushushu obuphakamileyo bunokubangela ukutshintshwa kobushushu benkqubo, ukunyuka kobushushu benkqubo, oku kuphelile, ukuvumela inkqubo ibe shushu.

Kukho izizathu ezininzi zokushisa ngaphandle kolawulo lweebhetri ze-lithium-ion. Ngokomzekelo, xa iziphelo zombini zebhetri ye-lithium ziqhagamshelwe, ukukrazula kwe-membrane yokwahlukaniswa kwe-electrode ye-lithium-ion yebhetri engalunganga kunye ne-electrode efanelekileyo iya kubangela isiphaluka esifutshane, kwaye isiphaluka esifutshane sivame ukubangela ukuphahlazeka kobushushu. Izizathu zeebhetri ze-lithium-ion zikwabandakanya: ubushushu be-ambient budlula i-60 ¡ã C, ngokuphindaphindiweyo ukuhlawula, umonakalo womzimba, njl.

Nokuba siyintoni na isizathu, amava ale mpendulo yi-cobalt oxide chemistry ebhetri. Ukuba ufudumeza le khemikhali, ifike kubushushu obuthile, iqala ukufudumala, emva koko iphuhlise ibe ngumlilo kunye nokudubula. Xa kuthelekiswa nebhetri ye-lithium yokuqala, ngoku ibhetri ye-lithium iye yaphucula ngokuphindaphindiweyo kwaye igqibelele, ekusebenzeni kokusebenza kokhuseleko, ngokude nje siqinisekisa ukusebenza okuchanekileyo kwiindawo eziqhelekileyo xa siqinisekisa ukusetyenziswa kwansuku zonke, Ngoko ke amathuba okuba iingxaki ngeebhetri ze-lithium zincinci.

I-Lithium ion ayinde, ngokuqhelekileyo iminyaka emibini ukuya kwemithathu (kungakhathaliseki ukuba uyayisebenzisa). Ngoko ke, zonke iipakethe zebhetri ze-lithium-ion kufuneka zitshintshwe kanye kwiinyanga ze-36; qaphela ukuphepha umonakalo womzimba kwibhetri ye-lithium, kuba umonakalo womzimba unokubangela isiphaluka esifutshane ngaphakathi kwebhetri; xa ibhetri igcinwe yodwa, ukugquma kufuneka kwenziwe. Ukuqinisekisa ukuba isiphelo soqhagamshelwano lwentsimbi yebhetri sigcinwe kuyo nayiphi na isinyithi, njengesitshixo, njl.

, ungasebenzisa ingxowa yeplastiki yokutywina eqhelekileyo ukubeka ibhetri; iqondo lokushisa eliphantsi kakhulu okanye liphezulu kakhulu, eliya kubangela umonakalo osisigxina kwibhetri ye-lithium, ngoko kufuneka kugwenywe ukuphepha ukushisa okunzima. Ibhetri yeLithium kwindawo. Kufuneka kwakhona kugwenywe ngemvula, ukucwiliswa kwamanzi, ukwenzela ukuba ungabangeli iisekethe ezimfutshane; nangona uninzi lweemveliso zedijithali, iisekethe zabo zokutshaja zangaphakathi zixhotyiswe ngamanyathelo okhuseleko ahambelanayo ukuphepha ukutshajiswa okugqithisileyo kweebhetri ze-lithium, kodwa kwi-inshurensi, kufuneka siphephe ukudibanisa iibhetri ze-lithium ixesha elide kunye netshaja.
