||||
|
Scope Of Application |
This product is mainly suitable for prelithiation of silicon carbon / silicon oxygen anode. |
||||
|
Product Advantages |
Improving performance: By using micron level microporous lithium film prelithiation, the battery's initial efficiency can be increased to 100%, energy density can be increased by 9-20%, and cycle times can be increased by more than 30%. Safe to use: The product is a continuous film material that can be safely used in a dry environment (dew point≤-40℃) Fast prelithiation speed: The micropores on the lithium film are conducive to rapid electrolyte penetration, and can be quickly prelithiated after soaking in the electrolyte. Accurate lithium supplementation: Compared to lithium powder (usually D50≥40μm) prelithiation, micron level microporous lithium film takes up less space for anode thickness, and the lithium replenishment amount is more accurate and uniform. High process compatibility: Highly compatible with existing battery production processes, micron level microporous lithium film can be transferred to the anode surface by using prelithiation equipment. Mature technology: The full set of technical solutions has been validated with no technical risks. |
