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...

Important performance indicators of lithium-ion batteries1. Battery capacityThe capacity of a battery is divided into additional capacity and actual capacity. The additional capacity of a battery refers to the capacity of the battery at 20 ℃; The amount of electricity that should be supplied when d...

Structure and principleThe olivine structured lithium iron phosphate inside the lithium iron phosphate battery serves as the positive electrode of the battery, which is connected to the positive electrode of the battery through a separator between aluminum foil and polymer to distinguish between pos...
