▎ 摘  要

NOVELTY - Conductive paste, comprises nano-carbon materials and nano-silicon materials, which are uniformly dispersed in the liquid reagent through the action of a specific dispersant. The nano-carbon material and the nano-silicon material are combined into a whole through chemical bonding or physical interaction, and the nano-silicon surface contains or does not contain hydroxy or carboxy groups. USE - The conductive paste is useful for preparing lithium ion battery. ADVANTAGE - The prepared product improves the conductive/heat conducting performance of the battery system, at the same time, effectively improving the energy density of the related battery. The preparation synthesis process has no waste gas, no pollution to the environment, and 3, the synthesis process is short in period and high in yield. The method has short synthesis period, low energy consumption and environment-friendly, and the synthesized silicon-carbon composite conductive slurry satisfy large multiplying power, large capacity and fast charging and discharging requirements, and is suitable for high energy density lithium ion battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of conductive paste.
