Yiziphi izinzuzo zebhethri ye-polymer lithium ion

Okokuqala, uhlobo lwesakhiwo sebhethri le-lithium-ion le-polymer lisebenzisa ukupakishwa okuguquguqukayo kwepulasitiki yensimbi yepulasitiki, okuhlukile kugobolondo lepulasitiki lebhethri elikwazi ukushajwa kabusha.Uma ubungozi bokuphepha sebukhiqiziwe, ibhethri elikwazi ukushajwa kabusha lijwayele ukuqhuma, futhi ibhethri eliwuketshezi elishajwa kabusha lineqhubu elinesimo somoya.

Yiziphi izinzuzo zebhethri ye-polymer lithium ion

Okwesibili, ibhethri elishajekayo liwugqinsi futhi lincane, lingenziwa libe yibhethri ye-lithium evamile eliwuketshezi.khetha esimweni esingokwezifiso kuqala, ngemva kwaleyo plug yebhethri ye-cathode impahla, ukushuba kwalezi zinkinga ezilandelayo zobuchwepheshe.Kodwa-ke, ibhethri ye-lithium ye-polymer ayinayo le nkinga, ubukhulu bamamilimitha alandelayo, ngokuhambisana nezidingo zokuma kwefoni ephathekayo.

Okwesithathu, uma kuqhathaniswa nebhethri elishajekayo le-aluminium igobolondo le-lithium elinemininingwane yevolumu efanayo, ikhwalithi ilula ngo-40%, kanti ibhethri elishajwayo le-aluminium elikhanyayo lingu-20%.

Okwesine, ibhethri le-lithium le-polymer elinamandla amakhulu liphakeme ngo-10% ~ 15% kunebhethri legobolondo le-aluminium elinezici ezifanayo, futhi liphakeme ngo-5% ~ 10% kunebhethri elishajekayo legobolondo le-aluminium.Kuyisinqumo esingcono kakhulu sokubonisa umakhalekhukhwini onemibala kanye nomakhalekhukhwini we-MMS.Njengamanje, izikrini eziningi ezimibalabala kanye namafoni we-MMS akhishwe emakethe yokuthengisa nawo ayayikhetha.

Okwesihlanu, ibhethri le-lithium le-polymer elinokumelana okuphansi kwangaphakathi lidinga ukuba lincane kunebhethri eligcwele uketshezi eliphinde lishajwe, ukumelana kwangaphakathi kwebhethri le-lithium yasekhaya le-polymer kunganciphisa kube ngaphansi kuka-35 mΩ okwamanje.Inciphisa kakhulu ukusetshenziswa kwamandla ebhethri elishajekayo, ikhulise impilo yebhethri kumakhalekhukhwini, lolu hlobo lwebhethri ye-lithium ye-polymer ngokushaja okukhulu kwamanje kanye nokukhishwa kulungele ukukhethwa okuhle kwesilawuli kude, enye ethembisa kakhulu ku-NIMH ekwazi ukushajwa. ibhethri.

Okwesithupha, ngokwesidingo sokuthuthukisa noma ukunciphisa ubukhulu bebhethri elishajekayo, ukuxhaphaza nokuklama amabhethri amasha, ikhwalithi ephezulu kanye nenani eliphansi, isikhathi somjikelezo wesikhunta esifushane, amanye amabhethri e-lithium e-polymer angenziwa ngokwezifiso ngokuya ngokubukeka kwefoni ephathekayo. , ukuze usebenzise ngokuguquguqukayo isikhala sasendlini segobolondo lebhethri elishajekayo, thuthukisa amandla ebhethri.

Okwesikhombisa, ibhethri ye-lithium ephezulu ye-polymer enezici ezinhle zokushajwa kanye nezici zokuphuma zisebenzisa isixazululo se-colloidal electrolyte, uma kuqhathaniswa nesisombululo se-electrolyte ewuketshezi, ishaja yesisombululo se-electrolyte ye-colloidal nezici zokukhipha izinzile, inkundla yokushaja neyokukhipha iphezulu.

Okwesishiyagalombili, kulula ukuklama ibhodi le-thermal insulation.Ingakhetha izinto zokusetshenziswa ze-polymer, ibhethri elishajekayo akulula ukulishisa futhi liqhume, ibhethri elishajekayo linesici sokuphepha esanele ngokwalo, ngakho-ke ingacabangela ukushiya i-PTC ne-PTC, bese yonga izindleko zebhethri elishajekayo.
