The progress of human society cannot be separated from the efforts of various industries in society, and the upgrading of various electronic products cannot be separated from the efforts of our designers. In fact, many people do not understand the composition of electronic products, such as lithium-...

With the continuous development of electronic technology, lithium batteries have gradually entered our daily lives. Whether it is smartphones, tablets, etc., lithium batteries can be seen. Generally speaking, the update and replacement speed of consumer electronic products is very fast. Therefore, t...

The secret of lithium-ion battery agingThe range of battery usage has always been a concern for researchers, as no matter how large the battery is, not charging it multiple times is meaningless. We all know that lithium-ion batteries reduce capacity during use, but no one understands why. Recently,...

Since the invention of lithium-ion batteries in the 1990s, graphite based negative electrodes have firmly occupied the mainstream position as negative electrode materials for lithium-ion batteries. This is not only due to the excellent electrochemical performance of graphite based negative electrode...

Due to the high weight specific capacity and volume specific capacity of silicon-based negative electrode materials, developing silicon-based negative electrodes is one of the most effective methods to improve the energy density of lithium-ion batteries. However, as an active substance, silicon unde...

Silicon, as a future negative electrode material, has a theoretical capacity of about 4200mAh/g, which is more than 10 times higher than the 372mAh/g of graphite negative electrodes. After industrialization, it will greatly enhance the capacity of batteries. However, the main problems with silicon m...

At present, the specific energy of power batteries is getting higher and the price is getting cheaper, and many of the pressures are transmitted to the materials. Without good materials, I think high specific energy batteries cannot be discussedAt the materials session of this year's conference,...

Firstly, an overview of negative electrode materialsThe main function of negative electrode materials is to store lithium during the charging process of lithium batteries. There are four main indicators for evaluating the performance of negative electrode materials: low lithium extraction voltage, h...

The separator is one of the important components of lithium-ion batteries, usually also known as battery separator, separator paper, ion separation membrane, etc. The main function of the separator in lithium-ion battery materials is to isolate the positive and negative poles to prevent self dischar...
