Silicon powder use for the rechargeable lithium battery cathode material:
Due to the high absorption rate of nanometer silicon and lithium batteries, the nano silicon for lithium can significantly increase the capacity of lithium battery (theory can reach 4000mA / h).
Nano silicon powder and graphite replace the nano carbon powder as raw materials for the lithium anode material, use the mechanical milling method for preparing the best ratio of silicon / graphite composites, silicon and graphite, which is 1:9. Composition Si-C composite material, can effectively reduce the expansion when silicon absorption lithium ions, increase the affinity with the electrolytic solution, and easily dispersed and can improve the cycle performance.
Nano silicon nanowires made of silicon powder used in rechargeable lithium battery anode material in or on the surface of the nano silicon powder coated graphite anode materials used in rechargeable lithium battery, rechargeable lithium batteries can be improved more than three times the capacity and charge-discharge cycles.
Furthe more silicon could apply for the painting use , for the further information please contact us freely.
