DETAILED DESCRIPTION - A polymer lithium ion low-temperature battery is composed of anode having compaction thickness of 53-82 mu m, cathode having compaction thickness of 55 plus minus 2-62 plus minus 2 mu m, diaphragm, electrolyte, aluminum plastic film and electrode ear. The anode contains anode active material chosen from lithium manganate, nickel-cobalt-lithium manganate and lithium-cobalt manganate, binder and electroconductor. The binder is polyvinylidene fluoride. The electroconductor is flaky graphite, vapor-grown carbon nanofiber, cyanuric fluoride or acetylene with specific surface area of 1500 plus minus 200 m2/g. The weight ratio of anode active material, flaky graphite, acetylene and vapor-grown carbon nanofiber is 85-96:1-5:1-3:1-4:1-3. The cathode contains cathode active material like artificial graphite or middle-phase carbon microspheres, binder and electroconductor. The binder is polyvinylidene fluoride, styrene-butadiene rubber or carboxymethyl cellulose. The elecroconductor is conductive carbon black, vapor-grown carbon nanofiber, or cyanuric fluoride. The weight ratio of cathode active material to styrene-butadiene rubber to carboxymethyl cellulose to carbon black to vapor-grown carbon nanofiber is 85-96:1-5:1-3:1-4:1-3.
