Ezikhathini zamuva nje, kube nemibiko eminingi mayelana nokuqhuma kwebhethri yeselula, okuphinde kwabangela ukunaka komphakathi nokungakhululeki. Pho kungani umakhalekhukhwini uqhuma? Kungakanani okungenzeka? Ngisigwema kanjani lesi simo? Uma kuqhathaniswa nobunye ubuchwepheshe bebhethri, ibhethri ye-lithium-ion ilula, ishibhile, futhi ukuminyana kwamandla nakho kuphezulu. Sekuyiyona ndlela eyinhloko yamabhethri aphinde ashajwe, kusukela kuzo zonke izinto kusukela kumakhalekhukhwini kuya kumalaptops ekusetshenzisweni kwamabhethri e-lithium ion.

Kodwa leli bhethri linenkinga, kwezinye izimo ezimbi kakhulu, lingase libe nomlilo wokuqhuma. Isizathu sokuthi kungani ibhethri ye-lithium-ion izoba nokuqhuma, okuyinhlekelele ebizwa ngokuthi "i-thermal out-control" inqubo. Empeleni, "i-thermal out-of control" iyinqubo yomjikelezo wempendulo yamandla: izinga lokushisa eliphakeme lingabangela ukudluliswa kokushisa kwesistimu, ukukhuphuka kokushisa kwesistimu, lokhu kuphelile, ukuvumela isistimu ukuthi ishise.

Kunezizathu eziningi zokuthi ukushisa kungalawuleki amabhethri e-lithium-ion. Isibonelo, lapho zombili iziphetho zebhethri ye-lithium zixhunywe, ukudabuka kolwelwesi lokuhlukaniswa kwe-electrode eyinegethi yebhethri ye-lithium-ion kanye ne-electrode ephozithivu kuzodala ukujikeleza okufushane, futhi isifunda esifushane sivame ukudala ukuphahlazeka kokushisa. Izizathu zamabhethri e-lithium-ion zihlanganisa: izinga lokushisa le-ambient lidlula u-60 ¡ã C, ngokuvamile ukukhokhiswa ngokweqile, ukulimala ngokomzimba, njll.

Kungakhathaliseki ukuthi yisiphi isizathu, isipiliyoni salokhu kusabela yikhemikhali ye-cobalt oxide ebhethrini. Uma ushisa leli khemikhali, lifinyelela izinga elithile lokushisa, liqala ukushisa, bese liba umlilo nokuqhuma. Uma kuqhathaniswa nebhethri ye-lithium yokuqala, manje ibhethri ye-lithium iye yathuthuka ngokuphindaphindiwe futhi iphelele, ekusebenzeni kokusebenza kokuphepha, inqobo nje uma siqinisekisa ukusebenza okulungile ezindaweni ezivamile lapho siqinisekisa ukusetshenziswa kwansuku zonke, Ngakho-ke amathuba okuba nezinkinga ngamabhethri e-lithium mancane.

I-Lithium ion ayinde, ngokuvamile iminyaka emibili kuya kwemithathu (kungakhathaliseki ukuthi uyayisebenzisa). Ngakho-ke, wonke amaphakethe ebhethri e-lithium-ion kufanele ashintshwe kanye njalo ezinyangeni ezingama-36; qaphela ukugwema ukulimala ngokomzimba ebhethri ye-lithium, ngoba ukulimala ngokomzimba kungase kubangele ukujikeleza okufushane ngaphakathi kwebhethri; uma ibhethri ligcinwe ngokuhlukana, ukwahlukanisa kufanele kwenziwe. Ukuqinisekisa ukuthi ukuphela kokuthinta ibhethri kuvikelwe kunoma iyiphi insimbi, njengokhiye, njll.

, ungasebenzisa isikhwama sepulasitiki sokuvala esivamile ukubeka ibhethri; izinga lokushisa elizungezile liphansi kakhulu noma liphezulu kakhulu, okuzodala umonakalo unomphela ebhethri ye-lithium, ngakho-ke kufanele kugwenywe ukugwema ukushisa okunzima. Ibhethri ye-lithium endaweni. Kufanele futhi kugwenywe imvula, ukucwiliswa kwamanzi, ukuze kungabangeli izifunda ezimfushane; nakuba imikhiqizo eminingi yedijithali, izifunda zabo zokushaja zangaphakathi zifakwe izinyathelo zokuvikela ezihambisanayo ukugwema ukushajwa ngokweqile kwamabhethri e-lithium, kodwa ngomshwalense, Kusafanele sikugweme ukuxhuma amabhethri e-lithium isikhathi eside kanye neshaja.
