 Products Description 

1) 0.5%~2% of CNT can be added to the negative electrode formula, which helps improve cycling performance

2) The amount of electrolyte additive is increased compared to that used in graphite negative electrode electrolyte additive, which contributes to improving the poor SEI film of silicon negative electrode

3) Use special adhesive for silicon-carbon materials (such as PAA series adhesive) to effectively improve the electrochemical performance of the materials (such as cycling performance, etc.)

Features: Ultra-high capacity.
Applicable scope: High-capacity batteries (especially suitable for cylindrical batteries).
Application fields: 3C special field.
