I-polymer ebizwa ngokuba yi-lithium ibhetri ibhekisela kwibhetri ye-lithium ion esebenzisa i-polymer njenge-electrolyte, kwaye ihlukaniswe ibe ziindidi ezimbini: "i-semi-polymer" kunye ne "yonke-polymer"."I-semi-polymer" ibhekisela ekugqumeni umaleko wepolymer (ngokuqhelekileyo i-PVDF) kwifilimu yesithintelo ukwenza i-adhesion yeseli yomelele, ibhetri inokwenziwa lukhuni, kwaye i-electrolyte iseyi-electrolyte engamanzi."Yonke i-polymer" ibhekisela ekusebenziseni i-polymer ukwenza inethiwekhi ye-gel ngaphakathi kweseli, kwaye ifake i-electrolyte ukwenza i-electrolyte.Nangona iibhetri "ze-polymer" zisasebenzisa i-electrolyte engamanzi, isixa sincinci kakhulu, esiphucula kakhulu ukusebenza kokhuseleko lweebhetri ze-lithium-ion.Ngokwazi kwam, yi-SONY kuphela ngoku ivelisa ngobuninzi “i-polymer”.iibhetri ze-lithium-ion.Ukusuka komnye umba, ibhetri yepolymer ibhekisa kusetyenziso lwefilimu yokupakisha ye-aluminiyam-yeplastiki njengepakethe yangaphandle yeebhetri ze-lithium-ion, ekwaziwa njengeebhetri ezithambileyo.Olu hlobo lwefilimu yokupakisha luqulunqwe ngamacandelo amathathu, oko kukuthi, i-PP layer, i-Al layer kunye ne-nylon layer.Ngenxa yokuba iPP kunye nenayiloni ziipholima, olu hlobo lwebhetri lubizwa ngokuba yibhetri yepolymer.

Umahluko phakathi kwebhetri ye-lithium ion kunye ne-polymer lithium ibhetri

1. Iimathiriyeli ekrwada zahlukile.Izinto eziluhlaza zeebhetri ze-lithium ion yi-electrolyte (ulwelo okanye ijeli);izinto ezikrwada ze-polymer lithium ibhetri i-electrolyte kuquka i-polymer electrolyte (i-solid okanye i-colloidal) kunye ne-electrolyte ye-organic.

2. Ngokumalunga nokhuseleko, iibhetri ze-lithium-ion zivele ziqhume kwindawo yokushisa kunye noxinzelelo oluphezulu;iibhetri ze-lithium ze-polymer zisebenzisa ifilimu yeplastiki ye-aluminium njengeqokobhe langaphandle, kwaye xa i-electrolytes ye-organic isetyenziswa ngaphakathi, abayi kugqabhuka nokuba ulwelo lushushu.

3. Iimilo ezahlukeneyo, iibhetri zepolymer zinokuba mfutshane, zenziwe ngokungathandabuzekiyo, kwaye zenziwe ngokungathandabuzekiyo.Isizathu kukuba i-electrolyte inokuba lukhuni okanye i-colloidal kunokuba ibe yinto engamanzi.Iibhetri zeLithium zisebenzisa i-electrolyte, efuna iqokobhe eliqinileyo.Ipakethe yesibini iqulethe i-electrolyte.

4. I-voltage yeeseli zebhetri yahlukile.Ngenxa yokuba iibhetri ze-polymer zisebenzisa izinto ze-polymer, zingenziwa kwidibaniso ye-multi-layer ukufezekisa i-voltage ephezulu, ngelixa umthamo wegama weeseli zebhetri ze-lithium yi-3.6V.Ukuba ufuna ukufezekisa amandla ombane aphezulu ekusebenzeni, iVoltage, kufuneka uqhagamshele iiseli ezininzi kuthotho ukwenza iqonga lomsebenzi elinombane ophezulu.

5. Inkqubo yokuvelisa iyahluka.I-battery ye-polymer incinci, ingcono imveliso, kwaye ibhetri ye-lithium ininzi, ingcono imveliso.Oku kuvumela ukusetyenziswa kweebhetri ze-lithium ukwandisa amasimi amaninzi.

6. Umthamo.Umthamo weebhetri zepolymer awuphucukanga ngokufanelekileyo.Xa kuthelekiswa nomthamo osemgangathweni weebhetri ze-lithium, kusekho ukunciphisa.

Izinto ezilungileyo zeipolymer lithium ibhetri

1. Ukusebenza kakuhle kokhuseleko.Ibhetri ye-lithium ye-polymer isebenzisa i-aluminium-iplastiki yokupakisha ethambileyo kwisakhiwo, esahlukileyo kwigobolondo yensimbi yebhetri yamanzi.Nje ukuba kwenzeke ingozi yokhuseleko, ibhetri ye-lithium ion ivele iqhume, ngelixa ibhetri yepolymer iya kuqhuma kuphela, kwaye ininzi iya kutshiswa.

2. Ubukhulu obuncinci bunokwenziwa bube mncinci, bube bukhulu kakhulu, ubukhulu bunokuba ngaphantsi kwe-1mm, bunokudityaniswa kumakhadi okuthenga ngetyala.Kukho i-bottleneck yobugcisa yobunzima beebhetri ze-lithium eziqhelekileyo ezingaphantsi kwe-3.6mm, kwaye ibhetri ye-18650 inomthamo osemgangathweni.

3. Ubunzima bokukhanya kunye nomthamo omkhulu.Ibhetri ye-electrolyte ye-polymer ayifuni iqokobhe lentsimbi njengepakethe yangaphandle ekhuselayo, ngoko xa umthamo ufana, i-40% ilula kune-shell shell ye-lithium ibhetri kunye ne-20% ilula kune-aluminium iqokobhe ibhetri.Xa umthamo umkhulu ngokubanzi, umthamo webhetri yepolymer mkhulu, malunga ne-30% ephezulu.

4. Ubume bungenziwa ngokwezifiso.Ibhetri yepolymer inokongeza okanye inciphise ubukhulu bebhetri ngokweemfuno ezibonakalayo.Ngokomzekelo, i-notebook entsha ye-brand edumileyo isebenzisa ibhetri ye-polymer ye-trapezoidal ukuze isebenzise ngokupheleleyo indawo yangaphakathi.

Iziphene ze-polymer lithium ibhetri

(1) Esona sizathu siphambili kukuba iindleko ziphezulu, kuba zinokucwangciswa ngokweemfuno zomthengi, kwaye ixabiso le-R&D apha kufuneka lifakwe.Ukongeza, iintlobo ngeentlobo zeemilo kunye neendidi kukhokelele kwiinkcukacha ezichanekileyo nezingalunganga zezixhobo ezahlukeneyo kunye nezixhobo kwinkqubo yokuvelisa, kwaye ngokuhambelanayo zandiswe iindleko.

(2) Ibhetri yepolymer ngokwayo ayinakuguquguquka okubi, nto leyo eziswa lucwangciso olubuthathaka.Kuhlala kuyimfuneko ukucwangcisa enye kubathengi ukusuka ekuqaleni umahluko we-1mm.

(3) Ukuba iphukile, iya kulahlwa ngokupheleleyo, kwaye kufuneka ukulawulwa kwesekethe yokukhusela.I-overcharge okanye i-overdischarge iya konakalisa ukuguqulwa kwezinto zangaphakathi zeekhemikhali zebhetri, eziya kuchaphazela kakhulu ubomi bebhetri.

(4) Ubomi bufutshane kune-18650 ngenxa yokusetyenziswa kwezicwangciso ezahlukeneyo kunye nezixhobo, ezinye zinolwelo ngaphakathi, ezinye zomile okanye i-colloidal, kwaye ukusebenza akukuhle njengeebhetri ze-cylindrical ze-18650 xa zikhutshwa ngokuphezulu.
