“” ibhekisela ekusebenziseni iipolymers njenge-electrolytes, ezahlulwe ngokukodwa kwii-semi-polymers kunye nazo zonke iipolymers. I-semi-polymer ibhekisela ekugqumeni i-polymer (ngokuqhelekileyo i-PVDF) kwisahluli ukwenza ibhetri ibe nzima kwaye ibhetri ibe nzima, ngelixa i-electrolyte iseyi-electrolyte engamanzi.

“Ipolymer iyonke” ibhekisa kusetyenziso lwepolymer ukwenza ijeli yenethiwekhi ngaphakathi kwebhetri, emva koko itofe i-electrolyte ukwenza i-electrolyte. Nangona zonke iibhetri zepolymer zisasebenzisa i-electrolyte engamanzi, ukusetyenziswa kwazo kuncitshiswe kakhulu, kuphucula kakhulu ukhuseleko lweebhetri ze-lithium. Ngokokwazi kwam, nguSony kuphela okwangoku ovelisa iibhetri ze-lithium ze-polymer.

Kwelinye icala, iibhetri zepolymer zibhekisa kwiibhetri ezisebenzisa ifilimu yeplastiki yealuminiyam njengokupakishwa kwangaphandle kweebhetri zelithium, ezaziwa ngokuba ziibhetri ezithambileyo. Ifilimu yokupakisha iqulunqwe ngumaleko wePP, i-Al layer kunye ne-nylon layer. Ngenxa yokuba i-polypropylene kunye ne-nylon zi-polymers, ezi seli zibizwa ngokuba ziiseli ze-polymer.

1. Ixabiso eliphantsi

Ixabiso lamazwe ngamazwe le-18650 li malunga ne-$ 1 / PCS, kwaye ixabiso le-2Ah li malunga ne-3 yuan / Ah. Ixabiso eliphantsi le-polymer lithium ibhetri yi-4 yuan / Ah, ixabiso eliphakathi liyi-5-7 yuan / Ah, kwaye ixabiso eliphakathi liyi-7 yuan / Ah. Ngokomzekelo, i-ATL kunye nothixo wamandla unokuthengisa malunga ne-yuan eyi-10 / ah, kodwa ii-singles zakho azifuni ukuzamkela.

2. Ayinakwenziwa ngokwezifiso

U-Sony uzama ukwenza iibhetri ze-lithium ezifana neebhetri ze-alkaline. 5 ibhetri, hayi. Iibhetri ezi-7 ziyafana kwihlabathi liphela. Kodwa inzuzo ebalulekileyo yeebhetri ze-lithium kukuba zinokuqulunqwa ngokweemfuno zabathengi, ngoko akukho mgangatho ofanayo. Ukuza kuthi ga ngoku, kukho imodeli enye kuphela ye-18650 kwishishini lebhetri ye-lithium, kwaye ezinye ziyilelwe ukuhlangabezana neemfuno zabathengi.

3. Ukhuseleko oluphantsi

Siyazi ukuba phantsi kweemeko ezigqithisileyo (ezifana nokugqithiswa, ukushisa okuphezulu, njl.), ukuphendulwa kweekhemikhali ezinobundlobongela kwenzeka ngaphakathi kwebhetri ye-lithium, okubangelwa ubuninzi begesi. Ibhetri ye-18650 ine-casing yensimbi enamandla athile. Xa uxinzelelo lwangaphakathi lufikelela kwinqanaba elithile, igobolondo yensimbi iya kuqhuma kwaye iqhume, ibangele izingozi ezinzulu zokhuseleko.

Yingakho igumbi apho ibhetri ye-18650 ivavanywa ngokuqhelekileyo ikhuselwe ngokuqinileyo kwaye ayikwazi ukufikelela ngexesha lovavanyo. Iibhetri zePolymer azinayo le ngxaki. Naphantsi kweemeko ezifanayo ezigqithisileyo, ngenxa yamandla aphantsi efilimu yokupakisha, uxinzelelo luya kuba luphezulu kancinci, ukuphuka akuyi kuqhuma, kwaye kwimeko embi kakhulu kuya kutshisa. Iibhetri zePolymer zikhuselekile kuneebhetri eziyi-18650.

4. Ubuninzi bamandla aphantsi

Umthamo oqhelekileyo webhetri ye-18650 unokufikelela malunga ne-2200mAh, ngoko ubuninzi bamandla bumalunga ne-500Wh / L, ngelixa ubuninzi bamandla ebhetri ye-polymer bunokusondela kwi-600Wh / L.

Kodwa iibhetri zepolymer nazo zineengxaki zazo. Into ebalulekileyo yindleko ephezulu, kuba inokuqulunqwa ngokweemfuno zomthengi, kwaye uphando kunye neendleko zophuhliso apha kufuneka zibandakanywe. Ngaphezu koko, imilo iyaguquka kwaye iindidi zibanzi. Iintlobo ezahlukeneyo zezixhobo ezingezizo ezisemgangathweni ezibangwe ngexesha lenkqubo yokwenziwa kwemveliso nazo zivelisa iindleko ezintsha. Ukungaguquguquki kakuhle kwebhetri yepolymer ngokwayo kuzisa ukuguquguquka koyilo, kwaye ihlala ihlengahlengiswa ukuze abathengi bavelise umahluko we-1mm.
