Latium polymer batri

lifiyamu polima batire

Lithium polima batire ndi mtundu wa batire yowonjezedwanso mu mawonekedwe ang'onoang'ono. Mabatirewa ndi abwino pazida zam'manja zomwe zimafunikira ma watts opitilira 3 koma osakwana ma watt 7, monga ma laputopu ndi mafoni am'manja. Mabatire a lithiamu polima adatchulidwa kuti asakanize ma ion a lithiamu ndi ma polima (chinthu chokhala ndi mamolekyu akulu) omwe amapanga mapangidwe awo.

Batire ya lithiamu polymer idapangidwa ndikupangidwa ndi ofufuza kumapeto kwa zaka za m'ma 1980. Batire yoyamba ya lithiamu polymer batire idapangidwa mu 1994 kuti igwiritsidwe ntchito pachipatala mwadzidzidzi, ndipo pafupifupi zaka 10 pambuyo pa kulengedwa kwake, idagwiritsidwa ntchito pa satellite ndi mlengalenga. Batire ya lithiamu polima yakhala ikugwiritsidwa ntchito m'mafoni am'manja kuyambira 2004, pomwe Sony idapanga foni yam'manja yoyamba yogulitsidwa pogwiritsa ntchito batri ya lithiamu ion.

Mabatire a lithiamu polima ndi osiyana ndi mabatire a lithiamu ion chifukwa alibe cholekanitsa pakati pa ma elekitirodi abwino ndi oipa. Ma polima omwe amagwiritsidwa ntchito mkati mwa mabatirewa amakhala ndi kusinthasintha kofanana ndi jelly, chifukwa chake amatchedwa ma cell a gel. Mabatire a lithiamu polima alinso ndi mwayi wokhala ndi mwayi wocheperako kutayikira kwa electrolyte poyerekeza ndi mitundu ina ya mabatire a lithiamu ion chifukwa palibe cholekanitsa chomwe chilipo.

Kuopsa kwa electrolyte kutayikira kumachitika ngakhale ndi mitundu ina yopanda lithiamu polima. Ngakhale batire ili yofanana ndi mabatire ena a lithiamu ion, zida zomwe zimagwiritsidwa ntchito mkati mwake ndizosiyana ndi mabatire achikhalidwe a lithiamu ion. The madzi electrolyte kuti zikugwirizana zabwino ndi zoipa mathero mkati mmene lifiyamu ion batire wapangidwa potaziyamu hydroxide kapena lithiamu hydroxide, amene amachitira ndi graphite mu elekitirodi zabwino pa kulipiritsa.

Chigawo china cha batri yothandiza ya lithiamu ion ndi graphite, yomwe kudzera muzochita ndi electrolyte imapanga misa yolimba yotchedwa carbon dioxide pentoxide, yomwe imagwira ntchito ngati insulator. Mu batire lifiyamu polima Komabe, ndi electrolyte wapangidwa poly(ethylene okusayidi) ndi poly(vinylidene fluoride), kotero palibe chifukwa graphite kapena mtundu wina uliwonse wa mpweya. Ma polima ndi zinthu zomwe ndi mamolekyu akulu, omwe amatha kukana kutentha kwambiri komanso dzimbiri.

Ma polima omwe amagwiritsidwa ntchito mkati mwa mabatire a lithiamu polima amapereka zinthu zomwe zimapanga kusasinthika kwa gel poyerekeza ndi mitundu ina ya mabatire a lithiamu ion. Electrolyte imapangidwa ndi organic zosungunulira zomwe zimatha kupangidwa popanda lithiamu, motero zimakhala zotsika mtengo kwambiri za batire.

Mabatire a lithiamu polymer amagwiritsidwa ntchito pazinthu zambiri chifukwa amatha kusinthasintha ndipo amatha kupirira kutentha kwambiri kuposa mitundu ina ya mabatire a lithiamu ion. Amalemeranso pang'ono poyerekeza ndi omwe adawatsogolera, zomwe zimalola wogwiritsa ntchito foni yam'manja nthawi yayitali osakumana ndi zowawa kapena zowawa m'manja ndi manja.
