Ibhetri yeLithium polymer

Ibhetri yeLithium polymer

Enye yezona zinto zingahoywayo kubomi bebhetri ngokwenene lixabiso lentlawulo-ibhetri iya kubonelela ngamandla amancinci kwisixhobo ukuba ihlawulwe yonke indlela.

Ngenxa yokwanda kokusetyenziswa kwebhetri ye-lithium polymer, ezi bhetri ziye zafumana ukuthandwa ngenxa yobunzima bazo obuphantsi kunye namazinga aphezulu entlawulo. Ukongezelela, zixhathisa ubushushu kunye nokufuma.

Kodwa ngaphandle kwazo zonke izibonelelo, kusekho icala elisezantsi elibalulekileyo: azihlali ixesha elide njengezinye iintlobo zeebhetri kuba zoma ngokukhawuleza xa zihlawulwe.

Kukho izisombululo ezininzi zale nto, kubandakanywa i-supersole (ingubo ekhethekileyo egcina iibhetri ze-lithium ion ukuba zome) kunye nezinye iindlela, kodwa kukho enye elandelwa luninzi lwabavelisi. Ngenxa yokuba ezi bhetri zingasebenzisi ulwelo lwesintu okanye uncamathisele i-electrolyte, zifuna ijeli ethambileyo ukuze isebenze njenge-electrolyte. Le gel ifakwe phakathi kwee-electrode ezimbini zebhetri kunye ne-voltage ephezulu esetyenzisiweyo kubo, yenza umbane wokuhamba phakathi kwee-electrode ezimbini.

Ibhetri iqukethe i-polymer (i-conductive, i-heat-resistant material) equkethe ityuwa ye-lithium kwaye le nto ijikelezwe yi-insulating liquid. Ulwelo olugqumayo lukhusela i-polymer ekuchithekeni kwaye luthintela i-electrolyte ekugqabhukeni kwidangatye ukuba kukho isiphaluka esifutshane sombane.

Ngenxa yobume bebhetri ye-lithium yepolymer, akukho electrolytes ezinokuphalala. Kuba akukho electrolyte ekhoyo, oku kuthintela nakuphi na ukubanakho ukuvuza ukuba kungenzeki. Oku kuthetha ukuba umngcipheko womlilo okanye uqhushumbo lungaphantsi kunebhetri ye-lithium ion yendabuko.

Kukwathatha ixesha elincinane kakhulu ukuhlawulisa ezi bhetri kwaye zinokugcina izinga elikhulu lokukhupha. Oku kwenza ukuba iinkampani zikwazi ukuphepha imfuno yokubiza.

Inzuzo

Inzuzo ephambili yeebhetri ze-lithium ze-polymer kukuba zilungile kakhulu ngokubhekiselele kumandla ombane. Oku kuthetha ukuba umthamo wokugcinwa kwamandla unyuswe kakhulu, okuya kuthetha ukuba amandla amaninzi anokugcinwa kwindawo efanayo kunye nokunciphisa ubunzima. Olunye uncedo kukuba kuthatha ixesha elincinci ukuba ibhetri iphinde itshaje, ngakumbi xa ithelekiswa neebhetri ze-lithium ion.

Ukujika

I-drawback ephambili kukuba iibhetri ze-lithium polymer ziyaziwa ngokumisa. Xa oku kusenzeka, ibhetri iyayeka ukusebenza, ngoko kuya kufuneka itshintshwe. Nangona kunjalo, kukho iindlela umntu anokuthi aphephe ngayo ingxaki yezi bhetri zokomisa kwaye ngaloo ndlela anciphise umngcipheko wokutshintshwa kwazo.

Ngokubanzi, iibhetri ze-lithium zepolymer zisesichengeni sokuwohloka ngokukhawuleza kwaye azikwazi ukunika uxinano lwamandla aphezulu. Itekhnoloji yangoku ye-lithium polymer ibiza kakhulu.
