Description

technical field [0001] The invention relates to the technical field of lithium battery negative electrode composite material production, in particular to a temperature-controlled lithium battery negative electrode composite material production device and a production method thereof. Background technique [0002] At present, common anode materials include carbon anode materials, tin-based anode materials, lithium-containing transition metal nitride anode materials, alloy anode materials and nano-scale anode materials. Lithium battery anode composite materials are mostly mixed with a variety of anode materials. [0003] The existing negative electrode composite material production device has the following shortcomings: 1. When a variety of negative electrode materials are mixed, they cannot be fully fused, resulting in a decline in the performance of the composite material produced; 2. When the composite material is produced, it is affected by temperature, and it is not easy to...
