18650 lithium battery 3.7 v manufacturers briefly discuss the gap between domestic and foreign 18650 lithium battery 3.7 v technologies

　　18650 lithium battery 3.7 v manufacturers briefly discuss the gap in 18650 lithium battery 3.7 v technology at home and abroad. According to 18650 lithium battery 3.7 v manufacturers: At present, the technical level of my country's 18650 lithium battery 3.7 v production and manufacturing equipment has been greatly improved, and the gap with internationally advanced countries has gradually narrowed, and in some fields it has begun to catch up with foreign countries. The technological gap between domestic and foreign lithium batteries is small, the degree of localization is extremely high, and more competition is concentrated among domestic brands.

　　Lithium batteries have very high production requirements and are particularly sensitive to humidity. Therefore, good equipment and factory conditions as well as high-quality technical workers must be used to produce qualified lithium batteries. The current gap between my country's 18650 lithium battery 3.7 v technology and foreign advanced technology mainly lies in the quality of raw materials, equipment, and the quality of technical workers. Therefore, from this perspective, companies that do not have a large amount of capital to invest in equipment and high-quality raw materials cannot produce power lithium-ion batteries with reliable quality.

　　The production technology of lithium batteries is basically mature in China. Due to the priority given to market price positioning, there are shortcomings in quality compared with foreign countries. But the price has a big advantage. my country's 18650 lithium battery 3.7 v separators have made major breakthroughs in dry process technology and now have world-class manufacturing levels. However, in the field of wet separators, domestic separator companies are limited by many factors such as process and technology. The product level is still low, and production equipment mainly relies on imports. There is a big gap between my country's separator products and foreign products in terms of thickness, strength, and porosity consistency, and product batch consistency also needs to be improved.

　　Due to the active promotion of our government, China is at the forefront of the world in the application of power lithium batteries and has accumulated valuable experience in the application of large-scale power lithium batteries. However, the technology of Japanese power lithium batteries is based on automated production lines, and the battery consistency is good; while the technology of most domestic power lithium batteries is based on semi-automatic or even manual production lines, and the battery consistency is poor. Whether it is spinel lithium manganese oxide battery or lithium iron phosphate battery, both my country and Japan are in the stage of small-scale trial production.

　　The gap between domestic and foreign power 18650 lithium battery 3.7 v technology is mainly reflected in three aspects: first, the individual indicators of domestic power batteries may be close to or even higher than those of foreign countries, but the overall indicators are low, especially in terms of battery pack life; second, in terms of product There is a big gap in reliability and consistency; third, the overall industrial scale is large, but there are problems of small scale and over-dispersion of individual enterprises.

　　The main markets for lithium batteries are in the United States, Europe, and Asia. Asia is mainly in China, Japan, and South Korea. Now our country is the main producer of batteries. From a business perspective, the United States has relatively strong R&D and design capabilities, Japan has relatively strict production regulations, and my country has surpassed Japan in market share and ranks first in the world.

　　At present, we still have relatively big problems in 18650 lithium battery 3.7 v materials, which are mainly reflected in:

　　First, high-end battery materials are currently not self-sufficient. There is a surplus of low-end materials and a shortage of high-end materials. There is still a lack of research on the production process of materials, and the stability of materials is still insufficient.

　　Second, there are still some problems with battery design, and multiple sets of batteries cannot yet meet demand.

　　Third, problems such as insufficient battery recycling planning and low-level production equipment still exist.
