Chifukwa chiyani mabatire ofewa a lithiamu polima amakhala okwera mtengo kuposa mabatire wamba?

Mawu Oyamba

Mabatire a lithiamu polima nthawi zambiri amatchedwa mabatire a lithiamu polima. Mabatire a lithiamu polima, omwe amatchedwanso mabatire a lithiamu polima, ndi mtundu wa batri wokhala ndi mankhwala. Ndi mphamvu zambiri, zocheperako komanso zopepuka poyerekeza ndi mabatire wamba. Mabatire a lithiamu polima amakhala ndi mawonekedwe owonda kwambiri, kuti agwirizane ndi zosowa za zinthu zina, amapangidwa kukhala mawonekedwe osiyanasiyana ndi mphamvu ya batri, ndiye chifukwa chiyani mabatire ofewa a lithiamu adzakhala okwera mtengo? Kenako, tipitiriza kuyang'ana pa zofewa paketi lifiyamu polima batire mtengo kuposa batire wamba chifukwa mtengo?

Chifukwa chiyani mabatire ofewa a lithiamu polima amakhala okwera mtengo kuposa mabatire wamba?

Kusiyana pakati pa soft pack lithiamu polima ndi mawonekedwe a batri wamba.

Mabatire a lifiyamu a polima amatha kukhala ochepa thupi, mosintha mosintha komanso opangidwa mosintha chifukwa ma electrolyte awo amatha kukhala olimba kapena gelled osati madzi, pomwe mabatire a lithiamu amagwiritsa ntchito electrolyte ndipo amafunikira vuto lamphamvu ngati phukusi lachiwiri kuti agwire electrolyte. Chifukwa chake, izi zimathandizira pakuwonjezera kulemera kwa mabatire a lithiamu.

Magawo achitetezo a pakiti yofewa ya lithiamu polima ndi mabatire okhazikika

Panopa siteji ya polima makamaka zofewa paketi lifiyamu mabatire, ntchito zotayidwa pulasitiki filimu kwa chipolopolo, pamene mkati organic electrolyte ntchito, ngakhale madzi otentha kwambiri, si kuphulika, chifukwa aluminium-pulasitiki filimu polima batire. amagwiritsa ntchito cholimba kapena gel osakaniza popanda kutayikira, amangophulika mwachibadwa. Koma palibe chomwe chili mtheradi, ngati kamphindi kakanthawi kamakhala kokwanira komanso kulephera kwakanthawi kochepa kumachitika, sizingatheke kuti batire ingoyaka kapena kuphulika, ndipo zochitika zambiri zachitetezo ndi mafoni am'manja ndi mapiritsi zimayamba chifukwa chazimenezi.

Kusiyana kwakukulu pakati pa mabatire ofewa a lithiamu polima ndi mabatire wamba ndizinthu zopangira

Ichi ndiye gwero lonse la machitidwe osiyanasiyana a awiriwa. Mabatire a lifiyamu a polima ndi amene amagwiritsa ntchito zipangizo za polima mu chimodzi mwa zigawo zikuluzikulu zitatu: electrode positive, electrode negative kapena electrolyte. Polima amatanthauza kulemera kwakukulu kwa maselo, mosiyana ndi lingaliro la mamolekyu ang'onoang'ono, omwe ali ndi mphamvu zambiri, olimba kwambiri komanso othamanga kwambiri. Zida za polima zomwe zimapangidwa panthawiyi za mabatire a polima zimagwiritsidwa ntchito kwambiri mu cathode ndi electrolyte.
