AEROGEL TECH LLC [US]

US_2018162736_A1

Resumen de: US2020239319A1

For example, polyimide aerogels are prepared by mixing a dianhydride and a diisocyanate in a solvent comprising a pyrrolidone and acetonitrile at room temperature to form a sol-gel material and supercritically drying the sol-gel material to form the polyimide aerogel. Porous three-dimensional polyimide networks, such as polyimide aerogels, may also exhibit a fibrous morphology. Having a porous three-dimensional polyimide network undergo an additional step of pyrolysis may result in the three dimensional network being converted to a purely carbon skeleton, yielding a porous three-dimensional carbon network.

SILICON-CARBON COMPOSITE MATERIAL AND PREPARATION METHOD THEREOF

NºPublicación: WO2020151093A1 30/07/2020

Solicitante:

DONGGUAN KAIJIN NEW ENERGY TECH CORP LTD [CN]

CN_109802120_A

Resumen de: WO2020151093A1

Disclosed is a silicon-carbon composite material. The silicon-carbon composite material is a composite material having a structure resembling a dragon fruit, and comprises a matrix core, a silicon-carbon composite shell and a coating layer. The silicon-carbon composite shell is formed by uniformly dispersing nano-silicon particles in a conductive carbon. The nano-silicon particles are formed by high-temperature cracking of a silicon source. The conductive carbon is formed by high-temperature cracking of an organic carbon source. The coating layer is a carbon coating layer. The carbon coating layer comprises at least one layer, and the thickness of each layer is 0.2-3 μm. Compared with the prior art, the composite material utilizes vapor phase synchronous deposition to form a silicon-carbon composite material precursor, followed by carbon-coating to form the silicon-carbon composite material having a structure resembling a dragon fruit. The composite material has the advantages of high first cycle efficiency, low expansion, and a long cycle. The growth of silicon material grains during heat treatment is slowed, effectively avoiding powdering of the material during the cycle, alleviating volume expansion of the silicon-based material, and improving the material's cycle performance, electrical conductivity and rate performance.
