　　Lithium battery manufacturers briefly discuss what problems they face in the research and development of 3.7v 18650 lithium battery materials?

　　In the research and development of solid-state lithium batteries, universities, scientific research institutes and enterprises in my country have jointly worked hard to actively promote the research and development and industrialization of key materials for solid-state lithium batteries. They have taken the lead in realizing the industrialization of oxide electrolyte solid-state lithium batteries in the field of consumer batteries, forming a There are many innovations blooming on the three development routes of polymer electrolytes, oxide electrolytes and sulfide electrolytes.

　　3.7v 18650 lithium battery is a type of lithium battery that uses solid electrode materials and solid electrolyte materials. Unlike liquid lithium batteries and hybrid solid-liquid lithium batteries, the battery cells of solid lithium batteries do not contain any liquid electrolytes, liquid solvents and liquid additives. Solid-state lithium batteries show great advantages in safety, cycleability, high temperature resistance, energy density, etc., and have different performance requirements for materials.

　　Problems faced in the research and development of 3.7v 18650 lithium battery materials

　　1. R&D forces are scattered and lack overall coordination.

　　First, domestic institutions independently choose R&D routes, and due to poor communication due to business confidentiality, repeated investment in the R&D of many common technologies is a waste of resources; second, on some major technical problems, it is difficult to concentrate efforts to make breakthroughs in the absence of overall design; Third, in the international context where Japan, the United States, South Korea and other countries are accelerating their layout to seize the commanding heights of 3.7v 18650 lithium battery development, my country urgently needs to strengthen overall coordination and enhance industrial competitiveness.

　　2. Key technologies are restricted and products have low added value.

　　In terms of some key materials, my country still has the problem of low product added value, some high-end products are imported, and key core technologies are controlled by others.

　　3. Lack of industry standards and poor application promotion

　　The lack of industry standards related to solid-state lithium batteries will affect the upstream and downstream connections of solid-state lithium batteries, making coordinated development difficult. It will also cause the quality of key materials and products to be uneven, and the cost of solid-state lithium batteries to remain high, which is not conducive to the industrialization and market promotion of solid-state lithium batteries.

　　How to promote the development of key materials for solid-state lithium batteries in my country

　　① Strengthen top-level design and improve the industrial innovation system

　　② Break through core technologies and open up the road to industrialization

　　③Accelerate the construction of standards and enhance international influence

　　Among the various current new battery systems, solid-state lithium batteries use new solid-state electrolytes to replace the current organic electrolytes and separators. They have high safety, high volume energy density, and are widely compatible with different new high-specific-energy electrode systems. Further improving the mass energy density, it is expected to become the ultimate solution for the next generation of power batteries.

　　As one of the future battery technology directions to replace traditional lithium batteries, solid-state lithium batteries have attracted many domestic and foreign research institutions and enterprises to conduct research and development. There is still a long way to go in terms of solid electrolyte materials, interface performance optimization, electrode material selection, cost, and technology. To go forward, both the production process and the surrounding environment of the production line require a large amount of capital investment and strict parameter control. It is believed that with the promotion and deepening of R&D technology, the pace of 3.7v 18650 lithium battery industrialization will gradually accelerate.
