Decommissioned batteries are swept in by the overwhelming force. According to statistics from domestic consulting agencies, as of the end of 2019, the number of new energy vehicles in the country has exceeded 3.81 million. According to the average service life of power batteries of 5-7 years, by 2020, the cumulative scale of domestic retired power batteries may reach 200,000 tons.

Research progress of silicon-based anode materials for lithium-ion batteries

Research progress of silicon-based anode materials for lithium-ion batteries

Lithium-ion batteries are currently one of the most widely used secondary battery systems. Compared with other rechargeable batteries such as NiCd and NiMH, Li-ion batteries have higher energy density, higher operating voltage, limited self-discharge and lower maintenance costs. However, current commercial graphite anodes cannot meet the increasing energy density and operational reliability requirements of energy storage applications such as portable electronic devices and electric vehicles. Therefore, silicon, as a new-generation anode material, has attracted extensive attention from academia and business circles.

Application Difficulties of Silicon-Based Anode Materials for Lithium Batteries

Application Difficulties of Silicon-Based Anode Materials for Lithium Batteries

At present, the energy density of new energy vehicle power lithium-ion batteries still needs to be improved, and there is a long way to go to replace traditional fuel vehicles. The main way to improve the energy density of power lithium-ion batteries is to use new high-capacity positive and negative electrode materials. The theoretical specific capacity of silicon is as high as 4200mAh/g, which is more than 10 times that of graphite-based negative electrode materials. Therefore, it is considered by the industry as the next generation to replace graphite. Lithium battery anode material.

Due to the tightening of the subsidy policy for new energy vehicles, the control of production costs is very important for new energy vehicles. If the cost is too high, it has to be passed on to consumers, which may affect sales and long-term development.

Lithium battery anode materials: the core field of new energy vehicles, rapid growth to meet huge opportunities

Lithium battery anode materials: the core field of new energy vehicles, rapid growth to meet huge opportunities

The arrival of the era of new energy vehicles has become the main driving factor for lithium batteries and anode materials. Recently, the overall supply of negative electrode materials, an important raw material for lithium batteries, has been in short supply. According to industry insiders, currently affected by the tight supply of negative electrode graphitization, the overall supply of finished products is tight.

Graphite powder has a good neutron moderator

Graphite powder has a good neutron moderator

Used in atomic energy industry and defense industry: Graphite powder has a good neutron moderator and is used in atomic reactors. Uranium-graphite reactors are the most widely used atomic reactors. As a deceleration material in a power atomic energy reactor, it should have high melting point, stability and corrosion resistance, and graphite powder can fully meet the above requirements.

Determination of resistance value of graphite powder

Determination of resistance value of graphite powder

Graphite powder is a substance with very sensitive chemical reaction. Its resistivity will change in different environments, that is, its resistance value will change, but one thing will not change. Graphite powder is a good non-metallic conductive substance. One, as long as the graphite powder is kept uninterrupted in an insulating object, it will be energized like a thin wire. However, the resistance value is not an accurate number, because the thickness of the graphite powder is different. The resistance value of graphite powder will be different in different materials and environments.
