Ithiphu Ukuvimbela ukwehluleka kwebhethri leselula Amathiphu okuvikela ukungasebenzi kwebhethri lefoni ephathekayo Okungenani, ukuphepha kwamabhethri e-lithium polymer kubonakala kuphezulu kakhulu, njengezimo zokuqhunyiswa komlilo ngokuvamile okunzima ukugqekeza kuzo. Nokho, singakwazi futhi ukuqonda kusukela imibiko abezindaba ngezikhathi ezithile, ibhethri imililo, abantu bazizwa besaba. Mayelana nalokhu, i-Nanjing University of Science and Technology Chemistry Laboratory yenza ukuhlolwa kwangempela kokuphepha kokushajwa kwebhethri, futhi kufanele iphendule abantu ngezinga elithile.

Opharetha baselabhorethri bazobamba iqhaza ezimpawini ezimbili zebhethri ye-lithium-ion, eyodwa yamabhethri ajwayelekile, enye eyebhethri yokulimala kwesekethe. Ngemva kokushaja kwamahora angaphezu kuka-12, ibhethri elivamile alinakho okungavamile, kuyilapho ibhethri elimele lonakala ngemva kokuba izinga lokushisa likhuphukele kuma-degree angu-100. Ngezinye izikhathi, ibhethri yefoni ephathekayo izoqhuma lapho ishaja ibhethri ye-lithium-ion, kuyoba nesifunda sokulungisa ukuyivimbela ukuvimbela umonakalo webhethri ye-lithium-ion overpressure, overcurrent, njll.

Uma ibhethri lichichima, isistimu yokulungisa izokhomba ngokuzenzakalelayo, ishintshe isuka kwenkulu yamanje iye kwencane, ukuze iselula ingashajwa. Ngakho-ke, uma ibhethri ye-lithium ion ingazange yehluleke kumjikelezo weshaja nokugcinwa, ngisho noma ukushaja kwe-tank kungakhiwe, akwenzi umonakalo esakhiweni sebhethri, futhi akubangeli ukuqhuma kwebhethri. Ngokusho kwabezindaba okubikiwe ukuthi ibhethri lefoni ephathekayo iyaqhubeka nokubanga izimo zokuqhunyiswa kungenzeka ngenxa yesekethe yokulungisa umonakalo, kungacatshangwa ukuthi ibhethri lingaphansi kwamandla angaphandle, noma kukhona izinga lokushisa eliphezulu kanye nomswakama ohlobene nesipiliyoni esihlobene nemvelo.

Ukushaja umakhalekhukhwini kufanele kunake izinto ezimbalwa. Ngaphezu kwalokho, nakuba ukuphepha kwamabhethri e-lithium ion e-polymer kuphakeme kunalokho kwebhethri ye-lithium ion, qaphela amaphuzu ambalwa ekusetshenzisweni kwansuku zonke. Okokuqala, ukuqinisekisa ukusetshenziswa kwebhethri yangempela neshaja, yiqiniso, umkhiqizo wokuhlela umzimba odidiyelwe kakhulu awuyona inkinga.

Okwesibili ukuthi ifoni ephathekayo ayikwazi ukwesaba ukushaja isikhathi eside, kodwa qaphela imvelo yocingo oluphathwayo, ukuchithwa kokushisa kufanele kube ngcono, isibonelo, amafoni omakhalekhukhwini angase abe ngaphansi komcamelo, okuyingozi kakhulu. Okwesithathu, uma ibhethri lefoni ephathekayo ine-edema, kufanele uyeke ukuyisebenzisa ngokushesha. Ungakwazi ukushintsha ibhethri ngokushesha.

Ungalivuli ibhethri ukuze wenze inqubo evamile ngemva kokuthengisa, ungaqhubeki nokuyisebenzisa uma kungenjalo kungenzeka kakhulu. Kusukela kumabhethri okuqala e-nickel-hydrogen kuya kumabhethri e-lithium-ion anamuhla namabhethri e-lithium polymer, amabhethri eselula ngokuvamile ayathuthukiswa. Ngokuvamile, inqobo nje uma ukulungiswa kulungile, amabhethri eselula kunzima ukubangela ukuvutha kokuphepha komuntu siqu noma ukuqhuma, abathengi abakwazi ukukhathazeka kakhulu.
