Non-aqueous secondary electrochemical cell |
摘要 |
<p>A lithium cell, having positive and negative electrodes capable of occluding and releasing lithium and a non-aqueous electrolyte. The cell of the present invention includes a positive electrode, a negative electrode and a gelated electrolyte composed of a polyacrylonitrile containing high molecular material, a gamma -caprolactone containing non-aqueous solvent and an electrolyte salt mainly comprised of LiPF6, with the content of gamma -caprolactone in the gelated electrolyte being 30 mol% or less. With the gelated electrolyte composed of the polyacrylonitrile containing high molecular material, non-aqueous solvent and the electrolyte salt mainly composed of LiPF6, a carbide film is formed on the electrode surface, on contact with the flame, as a result of the carbonization of the high molecular material and the carbonization accelerating operation of LiPF6. This carbide film inhibits inflammation for realizing superior combustion retardant properties. <IMAGE></p> |
