During the production process of batteries, there may be fine dust particles and impurities in the air, as well as dust and burrs on the positive and negative electrodes. These factors can easily cause physical contact inside the battery and induce short circuits, greatly affecting its performance. In severe cases, it may even cause the battery cell to fail to charge, resulting in a "dead" battery...

The humidity requirement during the production process of lithium-ion batteries is very high, mainly because uncontrolled or excessive moisture can have adverse effects on the electrolyte. The electrolyte, composed of lithium salts and organic solvents, serves as the medium for ion transport within the battery and ensures the advantages of high voltage and high energy density for lithium-ion batte...

Lithium Battery Electrolyte has a significant impact on the charging and discharging performance (high and low temperature), lifespan (cyclic storage), and temperature applicability of batteries. Suitable solvents need high dielectric constant and low viscosity. Commonly used solvents are alkyl carbonates such as PC and EC, which have strong polarity, high dielectric constant, but high viscosity, ...

During the mixing machine, transportation, and coating processes of the mixer, foreign objects such as dust or long flocs are mixed into the coating liquid or fall onto the wet coating surface,The surface tension of the coating at this location is affected by external forces, resulting in a change in intermolecular forces. The slurry undergoes a slight transfer, and after drying, a circular mark i...

The micro-gravure coating method uses a gravure roll, the gravure roll surface is mounted on bearings, partially immersed in the feed pan, and the rotating shaft picks up the coating, After quantification by a flexible rigid scraper, the coating liquid is taken away by the reverse motion substrate to achieve uniform thin layer coating. The direction of rotation of the microgravure coating gravure ...

The charging/discharging efficiency and cycle performance of conventional sodium-ion batteries will deteriorate when the temperature increases, which limits the application range. Therefore, it is necessary to solve the problem of poor cycle performance at high temperatures. The following are several ways to improve high temperature cycle performance. 1. Add a certain amount of vinylene carbonate,...

1. Energy density; Since the density of solid is higher than that of liquid, if the same volume of solid electrolyte is used to replace the lithium battery electrolyte, the weight of the battery will increase, resulting in a decrease in the energy density (wh/kg) of the battery calculated by weight. The energy density of subsequent solid-state batteries will be significantly improved due to the us...
