Okokuqala, uhlobo lwesakhiwo se-polymer lithium-ion ibhetri isebenzisa iplastiki yeplastiki yeplastiki eguquguqukayo yokupakisha, eyahlukileyo kwiqokobhe leplastiki yebhetri ephinda itshajwe.Nje ukuba umngcipheko wokhuseleko uveliswe, ibhetri yolwelo etshajwayo ithanda ukudubula, kwaye ibhetri yolwelo etshajekayo inomthamo onesimo somoya kuphela.
Okwesibini, ibhetri etshajwayo bubunzima kwaye incinci, inokwenziwa ibe yibhetri encinci yelithium elulwelo.khetha kwimeko elungelelanisiweyo kuqala, emva kokuba iplagi yentsimbi yecathode yesixhobo, ubukhulu bezi ntsilelo zilandelayo zobugcisa.Nangona kunjalo, ibhetri ye-lithium ye-polymer ayinayo le ngxaki, ubukhulu beemilimitha ezilandelayo, ngokuhambelana neemfuno zokuqhelaniswa kwefowuni yeselula.
Okwesithathu, xa kuthelekiswa ne-aluminiyam iqokobhe i-lithium etshajwayo ibhetri enemithamo efanayo, umgangatho ukhaphukhaphu ngama-40%, kunye nebhetri elayitayo etshajwayo yi-aluminium ekhanyayo ngama-20%.
Okwesine, ibhetri ye-lithium ye-polymer enamandla amakhulu yi-10% ~ 15% ephezulu kune-aluminiyam iqokobhe ibhetri yeenkcukacha ezifanayo, kunye ne-5% ~ 10% ephezulu kuneqokobhe le-aluminiyam ephinda itshajwe.Lolona khetho lubalaseleyo lokubonisa umbala wefowuni ephathwayo kunye neselfowuni ye-MMS.Okwangoku, uninzi lwezikrini zokubonisa ezimibalabala kunye neefowuni ze-MMS ezikhutshwe kwimarike yokuthengisa nazo ziyayikhetha.
Okwesihlanu, ibhetri ye-lithium ye-polymer enokumelana okuphantsi kwangaphakathi kufuneka ibencinci kunebhetri ye-lithium etshajwayo ngokubanzi, ukuxhathisa kwangaphakathi kwebhetri ye-lithium yasekhaya kunokunciphisa ukuya ngaphantsi kwe-35 mΩ okwangoku.Inciphisa kakhulu ukusetyenziswa kwamandla ebhetri ehlaziywayo, yandisa ubomi bebhetri kwifowuni ephathwayo, olu hlobo lwebhetri ye-lithium ye-polymer kwintlawulo enkulu yangoku kunye nokukhutshwa kukulungele ukhetho olufanelekileyo lolawulo olude, eyona ndlela ithembisayo kwi-NIMH etshajwayo. ibhetri.
Okwesithandathu, ngokwesidingo sokuphucula okanye ukunciphisa ubukhulu bebhetri etshajwayo, ukuxhaphaza kunye nokuyila iibhetri ezintsha, umgangatho ophezulu kunye nexabiso eliphantsi, ixesha elifutshane lokungunda lokubumba, ezinye iibhetri ze-lithium ze-polymer zinokuthi zenziwe ngokwezifiso ngokubonakala kwefowuni ephathwayo. , ukuze usebenzise ngokuguquguqukayo indawo yangaphakathi yeqokobhe lebhetri etshajwayo, phucula amandla ebhetri.
Okwesixhenxe, ibhetri ye-polymer ephezulu ye-lithium enexabiso elihle kunye neempawu zokukhupha zisebenzisa isisombululo se-colloidal electrolyte, xa kuthelekiswa nesisombululo se-electrolyte engamanzi, intlawulo yesisombululo se-electrolyte ye-colloidal kunye neempawu zokukhupha zizinzile, iqonga lenkonzo yentlawulo kunye nokukhupha iphezulu.
Okwesibhozo, kulula ukuyila ibhodi yokugquma i-thermal. Inokukhetha izinto eziluhlaza ze-polymer, ibhetri etshajwayo akulula ukuyitshisa kwaye iqhume, ibhetri ehlaziywayo inokhuseleko olwaneleyo lodwa, ngoko inokuthathela ingqalelo ukushiya i-PTC kunye ne-PTC, ngoko gcina ixabiso lebhetri egcwalisekayo.
