With the rapid development of science and technology, the imminent depletion of fossil fuels and the increasingly serious environmental pollution caused by the improvement of living standards, all countries attach great importance to the development of renewable and sustainable clean energy from the sun and wind. However, for these intermittent renewable clean energy sources, good energy storage systems and devices are very important. Based on mass production and environmental protection and green concepts, the new generation of energy storage devices must meet the requirements of low-cost manufacturing process, low-polluting and recyclable materials, safe device operation, and long service life.
The negative electrode material refers to the raw material that constitutes the negative electrode in the battery. The negative electrode of lithium-ion battery is made of negative electrode active material carbon material or non-carbon material, binder and additive to make paste glue, which is evenly spread on both sides of copper foil, dried and rolled. The key to the successful fabrication of lithium-ion batteries lies in the preparation of negative electrode materials that can reversibly de/intercalate lithium ions.
