Xingxing New Materials and Wuke University carried out porous silicon technology cooperation

On November 24, Hubei Xingxing New Materials Co.
, Ltd.
signed a technology transfer agreement of 150 million yuan with Wuhan University of Science and Technology to carry out technical cooperation
in porous silicon projects.

Dai Baixiong, chairman of Hubei Xingxing New Materials Co.
, Ltd.
, introduced that porous silicon is used in the anode of new energy lithium-ion batteries, which can significantly improve the capacity of
lithium batteries.
As a key material to improve the capacity of lithium batteries, porous silicon has great technical difficulty
in research and development.

The team of Wuhan University of Science and Technology, which is responsible for the technology research and development of porous silicon projects, has been deeply engaged in lithium battery anode materials for more than 10 years, and has obtained more than 30 patents in the fields of lithium battery electrode materials and supercapacitors
.
The team leader said that the current lithium battery anode material on the market is graphite, the theoretical capacity of graphite is 372 mAh / gram, and replacing graphite with porous silicon carbon can effectively improve the energy density
of the battery.
The team developed porous silicon anode materials and mastered the core technologies such as porous silicon morphology control, volume expansion and high-efficiency carbon composite, which is a good choice
for the next generation of lithium battery anode materials.

At present, the project has settled in Qingchun Chemical Industry Park, Suizhou High-tech Zone, with a planned construction scale of 30,000 tons per year, and the project can create an annual output value of more than 20 billion yuan and profits and taxes of more than
3 billion yuan after completion.
