Ⅰ. Performance Advantages and Challenges of Silicon-Carbon Anode Materials (1) Electrochemical Characteristics of Silicon In lithium-ion battery anode research, silicon attracts significant attention due to its extremely high theoretical specific capacity. Upon full lithiation, silicon can form alloys with a specific capacity reaching 4200 mAh/g, nearly ten times that of conventional graphite. Thi...read more

Defects in lithium-ion battery coating originate from three main parts: the coating slurry, the coating window, and the coating drying process. In the slurry preparation process, incomplete dispersion introduces agglomerated particles; insufficient iron removal filtration introduces metal debris; and incomplete vacuum deaeration leaves behind numerous bubbles. Corresponding coating defects include...read more

The lithium battery separator acts as a protective barrier between the positive and negative electrodes, conducting ions but not electrons. In the ideal state after electrolyte filling and formation, the separator should maintain complete and flat contact with the electrodes. However, when we disassemble batteries, we often find severe wrinkling of the separator. (This can also be clearly observed...read more

Reasons for Self-Discharge in Lithium-Ion BatteriesJul 15 , 2025Self-discharge in lithium-ion batteries refers to the phenomenon where the battery's charge/voltage naturally decreases when disconnected from an external circuit (i.e., in an open-circuit state). This is an inherent characteristic of all batteries, though the degree varies. Lithium-ion batteries exhibit a relatively low self-discharge rate but are still affected. The primary causes can be categor...read more
