Black Silicon Carbon Composite Material Lithium Ion Battery Anode
Materials Battery Si C Anode Raw
Product Description:
This a kind of hard carbon prepared from plant raw materials. It has excellent performance in low temperature, rate, cycle and
safety. It is widely used in power battery, power supply, sodium ion
battery and so on.
As a new anode energy material, Nano Silicon Crabon anode material
has ultra-high theoretical specific capacity and low lithium
removal potential(<0.5v), and the voltage platform of silicon is
slightly higher than that of graphite, so it is difficult to cause
lithium dissection on the surface during charging, and the safety
performance is better.
The product is characterized with high capacity(≥400Ah/g), high
first efficiency(≥85%), good cycle performance, low volume
expansion and realization the SNNC and non crystalline of Si. It is
widely applied for 3C digital, power tools, electric vehicles
(EV/HEV/PHEV).

Nano Silicon Carbon Advantage
Cost Control in Silicon-carbon Anode
Solution: Using silicon processing waste from the photovoltaic industry as
raw material, composite it with graphite material, and finally
complete asphalt coating to maintain low-cost advantages in terms
of raw materials and processes.
Cycle life and expansion issues of silicon-carbon anodes
Solution: By combining the preparation process of nano silicon with graphite
coating industrial technology, uniform dispersion and complete
coating of nano silicon can be achieved, and low expansion, long
cycle life silicon carbon composite materials can be prepared.
Compatibility of Silicon-carbon Composite Materials with Existing
Processes and Battery Production Equipment
Solution: Based on the current production process of graphite negative
electrode materials, maintain the maturity of product technology
and compatibility with battery production equipment.
