Spinel LiMn2O4 has rich resources in China, low price, good thermal stability, and is the main material of battery cathode. During the storage of LiMn2O4 positive electrode under high temperature and

The properties of electrolyte, including electrolyte, solvent and additive, will affect the service life, specific capacity, rate charge discharge performance and safety performance of the battery. Th

The positive pole overcharge mainly occurs when the proportion of positive pole materials is too low, which leads to the capacity imbalance between electrodes, resulting in irreversible loss of lithiu

1. Large internal polarization!2. The electrode piece absorbs water and reacts with the electrolyte to form an air drum.3. The quality and performance of electrolyte itself.4. The liquid injection vol

When the overcharge voltage of lithium battery cell is higher than 4.2V, side effects will start to occur. The higher the overcharge voltage, the higher the risk. When the voltage of the lithium batte

1 Voltage grouping method Voltage grouping method can be divided into static voltage grouping method and dynamic voltage grouping method. The static voltage matching method is also called no-load matc
