Description

technical field

[0001] The present invention relates to a carbon fiber aggregate, a method for producing the carbon fiber aggregate, and an electrode mixture layer for a nonaqueous electrolyte secondary battery. Background technique

[0002] Carbon nanomaterials, especially with an average fiber diameter of 1 mu Ultrafine carbon fibers below m are used as nanofillers for high-performance composite materials due to their excellent properties such as high crystallinity, high electrical conductivity, high strength, high elastic modulus, and light weight. Its use is not limited to nano fillers for reinforcement for the purpose of improving mechanical strength, but also effectively utilizes the high electrical conductivity and high thermal conductivity of carbon materials, and studies its use as additive materials for electrodes of various batteries or capacitors, and electromagnetic wave shielding. Materials, conductive nanofillers for antistatic materials, or as nanofillers bl...
