Lithium ion battery and electrode structure thereof

Abstract

A lithium ion battery and an electrode structure thereof are provided. The electrode structure at least includes a current collecting substrate, an electrode active material layer on the current collecting substrate, and a complex thermo-sensitive coating layer sandwiched in between the current collecting substrate and the electrode active material layer. The complex thermo-sensitive coating layer at least contains two or more of PTC (positive temperature coefficient) materials so as to have adjustable stepped resistivity according to temperature rise.

Dependencies are inferred from the claim text.
