Flame retardant components for lithium batteries based on antimony nanomaterials

Abstract

The invention discloses a flame-retardant member for a lithium battery based on a ruthenium nano material, comprising: a porous film layer which is a concave structure, and the porous film layer comprises a first porous film layer and a second porous film layer, the first The pore film layer and the second porous film layer form a cavity structure, the void in the cavity structure is 0.1-0.25 μm, the void is filled with a heat-conducting medium; the base film layer is attached to the second porous film layer; a flame-retardant film layer deposited on the base film layer on the second porous film on the left side, the first flame-retardant film layer is nano-cerium oxide particles containing doped nano-silver, and the thickness is 0.06-0.1 a second flame-retardant film layer deposited on the base film layer on the second porous film on the right side, and the second flame-retardant film layer is barium chloride particles containing doped nano antimony trioxide, The thickness is 0.02 to 0.08 μm. The flame-retardant member of the invention has good flame retardant and impact properties, and avoids spontaneous combustion or explosion of the lithium battery.

Description

technical field [0001] The invention relates to the technical field of flame-retardant films. More specifically, the present invention relates to a flame-retardant member for lithium batteries based on antimony nanomaterials having good flame-retardant properties.
