Nano silicon-carbon negative electrode materials

Driven by large-scale investment in the lithium-ion battery industry, the demand for lithium-ion battery negative electrode materials continues to rise. Silicon negative electrodes have higher mass energy density and volume energy density than graphite negative electrodes. The mass energy density of lithium-ion batteries using Nano silicon-carbon negative electrode materials can be increased by more than 8%, and the volume energy density can be increased by more than 10%. At the same time, the cost of each kilowatt-hour battery can be reduced by at least 3%. Therefore, silicon negative electrode materials will have very broad application prospects....

Driven by large-scale investment in the lithium-ion battery industry, the demand for lithium-ion battery negative electrode materials continues to rise. Silicon negative electrodes have higher mass energy density and volume energy density than graphite negative electrodes. The mass energy density of lithium-ion batteries using Nano silicon-carbon negative electrode materials can be increased by more than 8%, and the volume energy density can be increased by more than 10%. At the same time, the cost of each kilowatt-hour battery can be reduced by at least 3%. Therefore, silicon negative electrode materials will have very broad application prospects.

In the field of large-scale energy storage, Nano silicon-carbon negative electrode materials will also have great application prospects. With the continuous improvement of industrialization and informatization, the power system presents significant characteristics such as the continuous increase in installed power generation capacity and power grid transmission and distribution capacity, the increase in the peak-valley load difference of modern power systems, the increase in the amount of renewable energy connected to the grid, the increase in the complexity of the power system, and the improvement of user-side requirements for power quality. As an excellent backup power source, energy storage power stations are gradually becoming one of the key technologies for building modern power systems. Lithium-ion batteries are currently the most widely used energy storage batteries. Compared with the electric vehicle field, the energy storage power station field has higher requirements for the energy density of lithium-ion batteries, and the use of Nano silicon-carbon negative electrode materials has proposed a possible solution to meet this demand.

At the same time, aerospace, shipbuilding and other fields have also put forward higher energy density and power density requirements for lithium-ion batteries, and nano-silicon-carbon materials are also the most promising lithium-ion battery negative electrode materials at this stage, and their application prospects are very broad.
