Title:
両親媒性有機化合物を含む分散体からの炭素質粒子のアモルファス炭素コーティング
Document Type and Number:
Japanese Patent JP6687531
Kind Code:
B2
Abstract:
The present disclosure relates to a process for preparing surface-modified carbonaceous particles, wherein said carbonaceous particles are coated with a surface layer of amorphous carbon by dispersing carbonaceous material with an amphiphilic compound, spray drying of the dispersion and subsequent calcination of the dried material. The disclosure also pertains to surface-modified carbonaceous particles coated with amorphous carbon, which can for example be obtained by the process of the invention. The present disclosure further relates to the use of the surface-modified carbonaceous particles in a variety of technical applications, such as its use as an active material for negative electrodes of lithium ion batteries. The present disclosure also relates to a carbon brush or a polymer composite material, and generally compositions comprising said surface-modified carbonaceous particles, optionally together with other carbonaceous or non-carbonaceous materials.
