  Hozirgi davrda hammamizga ma’lumki Li-ion batareyalariga bo’lgan talab hamda qiziqish ortib
  bormoqda. Bu turdagi batareyalarni elektrofizik parametrlarini yaxshilash muhim hisoblanadi.
  Malaya universitetida ilmiy lobaratoriyasida Li-ion batareya tayyorlandi. Li-ion batareya qattiq
  polimer elektrolitini tayyorlash uchun polimetilmetakrilat (PMMA), etilin korbonat (EC),
  litiytrifilumetansulfanat (LiTf), erituvchi sifatida tetragidrofuran (THF) moddalardan foydalanildi[1].
  Katodni tayyorlash uchun esa AQSH ning Sigma Aldrich firmasida ishlab chiqilgan: poliviniliden
  ftorid (PVdF M

  ), grafid, aktiv modda litiy permanganat (LiMn

  ) erituvchi sifatida
  Germaniyaning MERCK firmasida ishlab chiqilgan 1-metil-2-pirolidon (NMP), hamda alyuminiy
  folgadan foydalanildi. Anod uchun Li folgasidan foydalanildi. Namuna batareya CR 2032 holatiga
  keltirib olindi. Neware batareya testeri qurulmasi yordamida Li-ion batareyani zaryadlanish hamda
  zaryadsizlanishi o’rganildi.
