Silicon-based anode materials are regarded as one of the alternative products of the existing commercial carbon anode materials However, due to the large volume effect during charging and discharging, it is not commercialized.

[Introduction] Lithium batteries are widely used in today's human society, such as electric vehicles and portable electronic devices However, these commercial lithium batteries have low energy densities and cannot fully meet the needs of everyday use.

Introduction Lithium batteries play an indispensable role in our lives Our daily handsets, laptops, household appliances, etc.

We know that the electric car development in China already has more than 20 years, the energy conservation and environmental protection, and the advantages of convenient much people like, and disadvantages is obvious, the lack of life make electric cars in front of the motorcycle big brother always lift head, many experts and scholars also in hard study, thinking about how to change the kidney or kidney to make electric cars to regain confidence, among them the lithium battery is now a good solution, there is a big possibility of a repeat of the electric vehicle Ask easy answer: electric vehicle battery or lithium good？ So the question is: is lithium or lead-acid better? With the update and iteration of battery technology for electric energy vehicles, the development of lithium battery is likely to rise from red flower and double stick to the leader of the community.

With the continuous promotion of pollution prevention and control actions around the country, environmental problems in the transit and temporary storage of waste lead-acid batteries have become increasingly prominent, which has been attached great importance by the relevant departments of the state and gradually put on the national key control agenda The Ministry of Ecological Environment, the Development and Reform Commission, the Ministry of Industry and Information Technology and the Ministry of Housing and Construction have successively promulgated such laws and regulations as the Law on the Prevention and Control of Environmental Pollution by Solid Waste, the Implementation Plan of the Extended Producer Responsibility System, the Implementation Plan of the Domestic Waste Classification System, and the Pilot Work Programme of the Collection and Transfer Management System of Waste Lead Batteries.

Since the middle and late April, the market has been worried about the US sanctions against Russian nickel, and the supply tightening is expected to increase The nickel and Shanghai nickel have risen sharply, setting a new high in the past three years.
