Description
technical field [0001] The invention relates to the technical field of silicon-carbon negative electrode preparation for batteries, in particular to a silicon-carbon negative electrode material preparation device. Background technique [0002] In recent years, with the rapid growth of the power battery market, the rapid development of the upstream material field has been driven, and higher requirements have been put forward for the performance of negative electrode materials. The graphite technology route has gradually been unable to meet the requirements of high specific capacity. Enterprises began to adjust their strategic direction and increase the layout of new negative electrode materials. Among them, silicon carbon negative electrode materials have attracted much attention. The coating structure of silicon carbon negative electrode materials is to coat the surface of active material silicon with a carbon layer to alleviate the volume effect of silicon. enhance its cond...
