Flame retardant components for lithium batteries based on antimony nanomaterials

Abstract

The invention discloses an antimony nanometer material based flame retardant component for a lithium battery. The flame retardant component comprises a porous membrane layer, a base membrane layer, a first flame retardant membrane layer and a second flame retardant membrane layer, wherein the porous membrane layer is of a concave structure and comprises a first porous membrane layer and a second porous membrane layer; the first porous membrane layer and the second porous membrane layer form a cavity structure; a gap in the cavity structure is 0.1-0.258 micron; the gap is filled with a heat-conducting medium; the base membrane layer is attached to the second porous membrane layer; the first flame retardant membrane layer is deposited on the base membrane layer positioned on the second porous membrane layer on the left side; the first flame retardant membrane layer refers to antimonous oxide nanoparticles containing doped nano-silver and has the thickness of 0.06-0.1 micron; the second flame retardant membrane layer is deposited on the base membrane layer positioned on the second porous membrane layer on the right side; and the second flame retardant membrane layer refers to antimony chloride particles containing doped nanometer antimony trioxide and has the thickness of 0.02-0.08 micron. The flame retardant component disclosed by the invention has excellent flame retardant and impact properties, and spontaneous combustion or explosion of the lithium battery is avoided.
