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...

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-...

Lithium batteries are increasingly being used in simple electric bicycles. What is the difference between lithium batteries and lead-acid batteries? What is the correct charging method for lithium batteries, and what should be paid attention to when charging lithium batteries for the first time? Sha...

Primary batteryAs the name suggests, disposable batteries can only be used. When the chemical energy of the battery is converted into electrical energy for power supply, it cannot compensate for the original electrical energy through charging or other methods. Therefore, it will not be used again af...
