▎ 摘　　要

NOVELTY - Collector is made of resin material added with conductive particles, where the conductive particles and the resin material are spaced apart in the collector electrode, and in the X-Y direction, the number of conductive particles forming the conductive path does not exceed 20% of the total number of conductive particles, and in the Z direction, the number of conductive particles forming the conductive path is not less than 60% of the total number of conductive particles. USE - Collector for lithium ion battery (Claimed). ADVANTAGE - The collector does not easily active the majority of active substances in the X-Y direction when short circuiting, and thus is not prone to thermal runaway, and may also fully conduct in the Z direction, so that a battery can be charged and discharged normally, and the safety of the battery is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the collector electrode, which involves heating the resin to above the melting temperature and mixing uniformly with conductive particles, then squeezing the melted mixture with conductive particles into the rotating cold roller, the viscosity of the mixture increasing rapidly to form a film when it is cold, and then the film stretching to the corresponding thickness and internal structure through a set of stretching rods.
