  "textContent": "The present invention provides a coated separator for lithium ion battery and a method for preparing the same, comprising: selecting a base membrane, preparing a coating slurry and preparing a coated separator. In the preparation of the coating slurry, a graphitized carbon foam having a high heat transfer coefficient and a high porosity is used. Furthermore, a porous wood-derived carbon material is acidified at high temperature in catalysis of iron(III) nitrate for generating FeC and SP carbon and pore formation. A ceramic powder is modified, and by limiting the mass ratio of graphene oxide to nano-alumina, a nano-alumina hybrid powder is prepared, which is then compounded with micro-alumina, micro-boehmite, micro-silica, micro-magnesium hydroxide and a bacterial cellulose nano-particle. The particle sizes of the micro-alumina, the micro-silica and the micro-magnesium hydroxide are limited to improve the effective thermal conduction channels in an out-of-plane direction of the separator, thus improving the heat transfer coefficient of the separator. The addition of the bacterial cellulose effectively reduces internal stress on the surface of the separator and prolongs the service life of the battery.",
