Ibhethri polymer ibhetri

Esinye sezici ezishaywe indiva kakhulu zempilo yebhethri izinga lokushajwa - ibhethri izonikeza amandla amancane kudivayisi uma ishajwe yonke indlela.

Ngenxa yokwanda kokusetshenziswa kwebhethri le-lithium polymer, lawa mabhethri abelokhu ethola ukuduma ngenxa yesisindo sawo esiphansi kanye namazinga aphezulu wokushaja. Ukwengeza, amelana nakho kokubili ukushisa nomswakama.

Kodwa naphezu kwazo zonke izinzuzo, kusekhona ukwehla okubalulekile: awahlali isikhathi eside njengezinye izinhlobo zamabhethri ngoba oma ngokushesha lapho eshajwe.

Kunezixazululo eziningi zalokhu, kufaka phakathi i-supersole (i-coating ekhethekile egcina amabhethri e-lithium ion ukuba ome) nezinye izindlela, kodwa kukhona okuye kwalandelwa iningi labakhiqizi. Ngenxa yokuthi lawa mabhethri awalusebenzisi uketshezi lwendabuko noma anamathisele i-electrolyte, adinga ijeli ethambile ukuze isebenze njenge-electrolyte. Le jeli ibekwe phakathi kwama-electrode amabili ebhethri futhi nge-voltage ephezulu esetshenziswa kuwo, yakha umsinga kagesi ukuze ugeleze phakathi kwama-electrode amabili.

Ibhethri iqukethe i-polymer (i-conductive, into ekwazi ukumelana nokushisa) equkethe usawoti we-lithium futhi lokhu kuzungezwe uketshezi oluvikelayo. I-insulating liquid ivimbela i-polymer ukuthi ingachitheki futhi ivimbela i-electrolyte ekuqhumeni amalangabi uma kukhona i-short circuit kagesi.

Ngenxa yemvelo yebhethri ye-lithium polymer, awekho ama-electrolyte angachitheka. Njengoba ingekho i-electrolyte ekhona, lokhu kuvimbela noma yikuphi ukuvuza okungenzeka ukuthi kungenzeki. Lokhu kusho ukuthi ingozi yomlilo noma ukuqhuma iphansi ngisho kunebhethri ye-lithium ion evamile.

Kuthatha futhi isikhathi esincane kakhulu ukushaja lawa mabhethri futhi angagcina izinga elikhulu lokuphuma. Lokhu kwenza ukuthi izinkampani zikwazi ukugwema isidingo sokushaja.

Zuza

Inzuzo eyinhloko yamabhethri e-lithium polymer ukuthi mahle kakhulu ngokulingana kwamandla. Lokhu kusho ukuthi inani lokugcinwa kwamandla landa kakhulu, okuzosho ukuthi amandla amaningi angagcinwa endaweni efanayo kanye nesisindo esincane. Enye inzuzo ukuthi kuthatha isikhathi esincane ukuthi ibhethri lishaje, ikakhulukazi uma kuqhathaniswa namabhethri e-lithium ion.

Impendulo

I-drawback eyinhloko ukuthi amabhethri e-lithium polymer aziwa ngokoma. Uma lokhu kwenzeka, ibhethri liyayeka ukusebenza, ngakho-ke kuzodingeka lishintshwe. Kodwa-ke, zikhona izindlela umuntu angagwema ngazo inkinga yokuthi la mabhethri ome bese enciphisa ingozi yokuwashintsha.

Ngokuvamile, amabhethri e-lithium polymer asengozini yokuwohloka ngokushesha futhi awakwazi ukunikeza ukuminyana okukhulu kwamandla. Ubuchwepheshe bamanje be-lithium polymer buyabiza kakhulu.
