Ibhethri ye-lithium ebizwa ngokuthi i-polymer ibhekisela ebhethri ye-lithium ion esebenzisa i-polymer njenge-electrolyte, futhi ihlukaniswe yaba izinhlobo ezimbili: "i-semi-polymer" kanye "ne-polymer yonke".I-“semi-polymer” isho ukumboza ungqimba lwe-polymer (imvamisa i-PVDF) efilimini yokuvimbela ukwenza ukunamathela kweseli kuqine, ibhethri lingenziwa libe lukhuni, futhi i-electrolyte iseyi-electrolyte ewuketshezi."Yonke i-polymer" ibhekisela ekusetshenzisweni kwe-polymer ukwakha inethiwekhi yejeli ngaphakathi kweseli, bese ijova i-electrolyte ukuze yakhe i-electrolyte.Nakuba amabhethri "all-polymer" asasebenzisa i-electrolyte ewuketshezi, inani lincane kakhulu, okuthuthukisa kakhulu ukusebenza kokuphepha kwamabhethri e-lithium-ion.Ngokwazi kwami, yi-SONY kuphela okwamanje ekhiqiza ngobuningi “all-polymer”.amabhethri e-lithium-ion.Ngakolunye uhlangothi, ibhethri le-polymer libhekisela ekusetshenzisweni kwefilimu yokupakisha ye-aluminium-plastic njengephakeji yangaphandle yamabhethri e-lithium-ion, aziwa nangokuthi amabhethri e-soft-pack.Lolu hlobo lwefilimu yokupakisha lwakhiwe ngezingqimba ezintathu, okuyi-PP layer, i-Al layer nesendlalelo senayiloni.Ngenxa yokuthi i-PP nenayiloni ama-polymer, lolu hlobo lwebhethri lubizwa ngebhethri ye-polymer.

Umehluko phakathi kwebhethri ye-lithium ion nebhethri le-lithium le-polymer

1. Izinto zokusetshenziswa zihlukile.Impahla eluhlaza yamabhethri e-lithium ion i-electrolyte (uketshezi noma ijeli);izinto zokusetshenziswa zebhethri le-lithium le-polymer ama-electrolyte afaka i-polymer electrolyte (okuqinile noma i-colloidal) kanye ne-organic electrolyte.

2. Mayelana nokuphepha, amabhethri e-lithium-ion avele aqhume endaweni yokushisa ephezulu kanye ne-high-pressure;amabhethri e-polymer lithium asebenzisa ifilimu yepulasitiki ye-aluminium njengegobolondo langaphandle, futhi lapho kusetshenziswa ama-electrolyte ephilayo ngaphakathi, ngeke aqhume ngisho noma uketshezi kushisa.

3. Amajamo ahlukene, amabhethri e-polymer angaba mncane, akheke ngendlela engafanele, futhi akheke ngokunganaki.Isizathu siwukuthi i-electrolyte ingaba eqinile noma i-colloidal esikhundleni se-liquid.Amabhethri e-lithium asebenzisa i-electrolyte, edinga igobolondo eliqinile.Iphakheji yesibili iqukethe i-electrolyte.

4. I-voltage yebhethri yebhethri ihlukile.Ngenxa yokuthi amabhethri e-polymer asebenzisa izinto ze-polymer, angenziwa inhlanganisela yezendlalelo eziningi ukuze afinyelele amandla ombane aphezulu, kuyilapho amandla okuzisholo amaseli ebhethri ye-lithium engu-3.6V.Uma ufuna ukuzuza amandla kagesi aphezulu ekusebenzeni, i-Voltage, udinga ukuxhuma amaseli amaningi ochungechungeni ukuze wakhe iplathifomu yokusebenza yamandla kagesi aphezulu.

5. Inqubo yokukhiqiza ihlukile.Uma ibhethri le-polymer liba mncane, ngcono ukukhiqizwa, futhi ukushuba kwebhethri ye-lithium, ukukhiqizwa okungcono.Lokhu kuvumela ukusetshenziswa kwamabhethri e-lithium ukwandisa izinkambu eziningi.

6. Amandla.Amandla wamabhethri e-polymer awathuthukiswanga ngempumelelo.Uma kuqhathaniswa nomthamo ojwayelekile wamabhethri e-lithium, kusenokuncipha.

Izinzuzo zeibhethri ye-polymer lithium

1. Ukusebenza kahle kokuphepha.Ibhethri ye-lithium ye-polymer isebenzisa ukupakishwa okuthambile kwe-aluminium-plastic esakhiweni, okuhlukile kugobolondo lensimbi lebhethri eliwuketshezi.Uma kwenzeka ingozi yokuphepha, ibhethri ye-lithium ion imane iqhume, kuyilapho ibhethri le-polymer lizoqhuma kuphela, futhi ngokuvamile lizoshiswa.

2. Ugqinsi oluncane lungenziwa lube mncane, lube mncane kakhulu, ugqinsi lube ngaphansi kuka-1mm, lungahlanganiswa lube amakhadi esikweletu.Kukhona ibhodlela lobuchwepheshe logqinsi lwamabhethri e-lithium awuketshezi ajwayelekile angaphansi kuka-3.6mm, futhi ibhethri lika-18650 linevolumu emisiwe.

3. Isisindo esincane kanye nomthamo omkhulu.Ibhethri ye-polymer electrolyte ayidingi igobolondo lensimbi njengepakethe yangaphandle evikelayo, ngakho-ke uma umthamo ufana, ilula ngo-40% kunebhethri ye-lithium yegobolondo lensimbi kanye no-20% ilula kunebhethri yegobolondo le-aluminium.Uma ivolumu ngokuvamile inkulu, umthamo webhethri ye-polymer mkhulu, cishe ngo-30% ngaphezulu.

4. Umumo ungenziwa ngezifiso.Ibhethri le-polymer lingangeza noma linciphise ukujiya kweseli yebhethri ngokwezidingo ezingokoqobo.Isibonelo, i-notebook entsha yomkhiqizo odumile isebenzisa ibhethri ye-trapezoidal polymer ukuze isebenzise ngokugcwele indawo yangaphakathi.

Ukukhubazeka kwebhethri ye-polymer lithium

(1) Isizathu esiyinhloko siwukuthi izindleko ziphakeme, ngoba zingahlelwa ngokuvumelana nezidingo zekhasimende, futhi izindleko ze-R&D lapha kufanele zifakwe.Ngaphezu kwalokho, ukuhlukahluka kobumo nezinhlobonhlobo kuholele ekucacisweni okulungile nokungalungile kwamathuluzi ahlukahlukene kanye nezinhlelo zenqubo yokukhiqiza, futhi ngokuhambisanayo zanda izindleko.

(2) Ibhethri ye-polymer ngokwalo inokuguquguquka okungalungile, okubuye ilethwe ukuhlela okubucayi.Ngokuvamile kuyadingeka ukuhlela eyodwa kumakhasimende kusukela ekuqaleni umehluko we-1mm.

(3) Uma iphukile, izolahlwa ngokuphelele, futhi ukulawulwa kwesifunda sokuvikela kuyadingeka.Ukukhokhisa ngokweqile noma ukuchichima ngokweqile kuzolimaza ukubuyiseleka emuva kwezinto zamakhemikhali zangaphakathi zebhethri, okuzothinta kabi impilo yebhethri.

(4) Isikhathi sokuphila sifushane kuno-18650 ngenxa yokusetshenziswa kwezinhlelo nezinto zokwakha ezahlukene, ezinye zinoketshezi ngaphakathi, ezinye zomile noma ziyi-colloidal, futhi ukusebenza akukuhle njengamabhethri angama-cylindrical angu-18650 lapho ekhishwa ngamandla aphezulu.
