The endurance of new energy vehicles depends on the energy density of the battery, the potential of the energy density of traditional graphite anode materials has been fully tapped, the performance is close to the theoretical limit, the theoretical specific capacity of silicon-carbon anode materials can reach more than 10 times that of graphite, and has the advantages of low cost and high efficiency of the first Coulomb, and the application prospects are very broad
.
However, silicon-carbon anode materials have two problems
: poor conductivity and poor battery cyclability caused by high expansion rate.
While having obvious advantages, how to overcome the defects of silicon-carbon anode materials has become a major issue
in the industry.

SiBao Technology's patented technology was born
for this purpose.
This technology innovatively uses the special structure and organic functional groups of silane coupling agents to form a solid network structure protective layer
tightly bound to the body on the surface of silicon oxide through chemical reactions.
This protective layer of mesh structure can effectively suppress the cracking of silicon oxide and volume expansion effect
.
Carbon nanotubes have good conductivity, and the modified silicon oxide is composited to form a three-dimensional structure, which can better inhibit the volume expansion of silicon oxide, and the conductive layer is not easy to fall off, so as to improve the conductivity of the material and improve the cycling performance of
the electrode material.

In November 2021, SiBao Technology established a wholly-owned subsidiary Silicon Bao (Meishan) New Energy Materials Co.
, Ltd.
, with a total investment of RMB 560 million to build 10,000 tons/year of silicon-carbon anode materials for lithium batteries, a 40,000-ton/year special adhesive production base and a lithium battery material R&D center, so as to prepare
for the industrialized large-scale production of silicon-carbon anode materials of the company.
Under the impetus of Sibao, the technology and industrialization of domestic silicon-carbon anode materials have made rapid progress
in the past two years.
