It is a silicon-carbon composite material
Huawei creates new material to extend battery life.
According to the patent description, we are talking about a durable composite material, which includes a core (core) covered with an alkaline layer. The silicon core is filled with amorphous carbon, while the pore size does not exceed 50 nm.
The patent states that the silicon-carbon composite material’s tiny pore structure effectively reduces the contact area between the silicon material and the electrolyte, which reduces the likelihood of side reactions and extends battery life.
Simultaneously, the graphite framework can effectively reduce the volumetric expansion and contraction of the material to improve the structural stability and energy density of the composite material.
How much more efficient such batteries will be is still unknown.
