Otchedwa polima lithiamu batire amatanthauza batire lifiyamu ion kuti ntchito polima monga electrolyte, ndipo lagawidwa mitundu iwiri: "semi-polymer" ndi "zonse polima"."Semi-polymer" amatanthauza ❖ kuyanika wosanjikiza wa polima (kawirikawiri PVDF) pa chotchinga filimu kuti selo adhesion mphamvu, batire akhoza kukhala olimba, ndi electrolyte akadali madzi electrolyte."Polima zonse" amatanthauza kugwiritsa ntchito polima kupanga netiweki ya gel mkati mwa selo, kenako kubaya electrolyte kupanga electrolyte.Ngakhale mabatire a "polymer" amagwiritsabe ntchito electrolyte yamadzimadzi, kuchuluka kwake ndi kochepa kwambiri, zomwe zimathandizira kwambiri chitetezo cha mabatire a lithiamu-ion.Momwe ndikudziwira, SONY yokha ndiyo yomwe ikupanga "all-polymer"mabatire a lithiamu-ion.Kuchokera ku mbali ina, batire ya polima imatanthawuza kugwiritsa ntchito filimu yoyika aluminium-pulasitiki ngati batire lakunja la lithiamu-ion, omwe amadziwikanso kuti mabatire a pack-pack.Filimu yonyamula yamtunduwu imapangidwa ndi zigawo zitatu, zomwe ndi PP wosanjikiza, wosanjikiza wa Al ndi wosanjikiza wa nayiloni.Chifukwa PP ndi nayiloni ndi ma polima, batire yamtunduwu imatchedwa batire ya polima.

Kusiyana pakati pa batri ya lithiamu ion ndi batri ya polymer lithiamu

1. Zopangira ndizosiyana.Zopangira za mabatire a lithiamu ion ndi electrolyte (madzi kapena gel osakaniza);zopangira za batire ya polima lithiamu ndi ma electrolyte kuphatikiza ma electrolyte a polima (olimba kapena colloidal) ndi ma electrolyte organic.

2. Pankhani ya chitetezo, mabatire a lithiamu-ion amangophulika kumalo otentha kwambiri komanso othamanga kwambiri;Mabatire a polymer lithiamu amagwiritsa ntchito filimu ya pulasitiki ya aluminiyamu ngati chipolopolo chakunja, ndipo ma electrolyte a organic akagwiritsidwa ntchito mkati, sangaphulike ngakhale madziwo atentha.

3. Mawonekedwe osiyanasiyana, mabatire a polima amatha kukhala owonda, owoneka bwino, komanso opangidwa mwachisawawa.Chifukwa chake ndi chakuti electrolyte ikhoza kukhala yolimba kapena colloidal osati madzi.Mabatire a lithiamu amagwiritsa ntchito electrolyte, yomwe imafunikira chipolopolo cholimba.Chovala chachiwiri chimakhala ndi electrolyte.

4. Mphamvu yamagetsi ya batri ndi yosiyana.Chifukwa mabatire a polima amagwiritsa ntchito zida za polima, amatha kupangidwa kukhala mitundu ingapo kuti akwaniritse voliyumu yayikulu, pomwe mphamvu mwadzina ya maselo a batire a lithiamu ndi 3.6V.Ngati mukufuna kukwaniritsa mkulu voteji kuchita, Voltage, muyenera kulumikiza maselo angapo mu mndandanda kupanga abwino mkulu-voteji ntchito nsanja.

5. Njira yopanga ndi yosiyana.Kuchepa kwa batire ya polima, kupanga bwino, komanso kuchulukira kwa batri ya lithiamu, kupanga kwabwinoko.Izi zimathandiza kugwiritsa ntchito mabatire a lithiamu kukulitsa minda yambiri.

6. Mphamvu.Kuchuluka kwa mabatire a polima sikunasinthidwe bwino.Poyerekeza ndi muyezo mphamvu lithiamu mabatire, akadali kuchepetsa.

Ubwino wapolymer lithiamu batire

1. Kuchita bwino kwachitetezo.Batire ya lithiamu ya polima imagwiritsa ntchito zopangira zofewa za aluminium-pulasitiki, zomwe ndizosiyana ndi chipolopolo chachitsulo cha batri yamadzimadzi.Chiwopsezo chachitetezo chikachitika, batire ya lithiamu ion imangophulika, pomwe batire ya polima imangophulika, ndipo nthawi zambiri imawotchedwa.

2. Makulidwe ang'onoang'ono amatha kukhala owonda kwambiri, owonda kwambiri, makulidwe amatha kukhala osakwana 1mm, atha kusonkhanitsidwa kukhala makhadi a ngongole.Pali luso botolo kwa makulidwe a wamba madzi lithiamu mabatire pansi 3.6mm, ndi batire 18650 ali voliyumu yokhazikika.

3. Kulemera kwakukulu ndi mphamvu zazikulu.Batire ya electrolyte ya polima sifunikira chipolopolo chachitsulo ngati chotchinga chakunja choteteza, kotero mphamvu ikakhala yofanana, ndi 40% yopepuka kuposa chitsulo chachitsulo cha lithiamu batire ndi 20% yopepuka kuposa batire ya aluminiyamu.Pamene voliyumu nthawi zambiri imakhala yayikulu, mphamvu ya batire ya polima ndi yayikulu, pafupifupi 30% apamwamba.

4. Mawonekedwewo akhoza kusinthidwa.Batire ya polima imatha kuwonjezera kapena kuchepetsa makulidwe a cell ya batri malinga ndi zosowa zenizeni.Mwachitsanzo, kope latsopano la mtundu wotchuka limagwiritsa ntchito batri ya trapezoidal polymer kuti igwiritse ntchito mokwanira malo amkati.

Zowonongeka za batri ya polymer lithiamu

(1) Chifukwa chachikulu ndikuti mtengo wake ndi wapamwamba, chifukwa ukhoza kukonzedwa malinga ndi zosowa za kasitomala, ndipo mtengo wa R & D pano uyenera kuphatikizidwa.Kuphatikiza apo, mitundu yosiyanasiyana ya mawonekedwe ndi mitundu yapangitsa kuti pakhale zolondola komanso zolakwika za zida ndi zida zosiyanasiyana popanga, ndikuwonjezeranso ndalama.

(2) Batire ya polima palokha ili ndi kusinthasintha kosasinthika, komwe kumabweranso ndikukonzekera tcheru.Nthawi zambiri zimakhala zofunikira kukonzekera imodzi kwa makasitomala kuyambira pachiyambi kusiyana kwa 1mm.

(3) Ngati chathyoledwa, chidzatayidwa, ndipo kuwongolera dera lachitetezo kumafunika.Kuchulukirachulukira kapena kuchulukirachulukira kumawononga kusinthika kwa zinthu zamkati za batri, zomwe zingakhudze kwambiri moyo wa batri.

(4) Kutalika kwa moyo ndi kochepa kuposa 18650 chifukwa chogwiritsa ntchito mapulani ndi zipangizo zosiyanasiyana, ena ali ndi madzi mkati, ena ndi owuma kapena a colloidal, ndipo ntchitoyo si yabwino ngati 18650 mabatire a cylindrical akatulutsidwa pakalipano.
