| titleOfInvention | A negative electrode sheet and lithium ion battery |
| abstract | A negative electrode sheet and a lithium ion battery belong to the technical field of lithium ion batteries. The negative electrode sheet includes a negative electrode current collector and a film layer coated on the negative electrode current collector; the film layer is divided into two layers, the first layer of coating film layer is the bottom graphite coating near the negative electrode current collector; the second layer of coating film The layer is a silicon-containing coating on the top layer away from the copper foil; using the double-layer coating technology, two kinds of slurries are simultaneously coated on the negative electrode current collector, and a double-layer paste coating structure is formed on the same side of the negative electrode current collector, and then the preparation is made. The silicon-containing coating layer is on the top layer, and the pure graphite layer without silicon is on the bottom layer. The double-layer coated negative electrode sheet has both high compaction and high capacity performance, and the preparation method is simple and convenient. The lithium-ion battery has the advantages of high energy density and good cycle performance, and at the same time, it can avoid lithium precipitation on the surface of the negative electrode plate under the fast charging of a large rate, which can meet the needs of industrial applications. |
