The future of lithium-ion batteries
Although lithium-ion batteries have achieved great commercial success, their development has not been smooth sailing. For lithium-ion batteries and their researchers, opportunities and challenges coexist. According to the research and development of new lead-acid batteries in 2011 and the integration in my country’s lead-acid battery industry, Japanese researchers have used sodium-sulfur batteries in energy storage, as well as lithium-sulfur batteries and lithium-air batteries that research institutes and schools have paid attention to in recent years. The development of batteries will have an impact on the current lithium-ion market. In particular, there are research reports that a major technological breakthrough by researchers in the United States in the near future may be that lithium-air batteries have the potential to achieve a major leap in battery technology because they reduce weight and complexity compared with standard batteries. . All components of the standard battery are stored inside, while the lithium-air battery uses oxygen in the air. However, the biggest problem facing this technology is that the active oxygen reacts with other battery components. Researchers have discovered an electrolyte material that does not react with oxygen, allowing the battery to maintain stable performance after multiple charges and discharges. According to the estimation of the researcher, in theory, the battery storage capacity can reach 10 times of the existing lithium-ion batteries on the market. For researchers of lithium-ion batteries, the most urgent task is to further reduce the cost of raw materials and improve battery cycle performance and stability through process innovation. From the perspective of technological development, the following three aspects should be given great attention:
(1) Develop large-capacity lithium-ion power lithium-ion batteries for electric vehicles;
(2) Develop and use new high-performance electrode materials, especially the development of high-performance cathode materials;
(3) To further reduce the cost of lithium-ion batteries and improve battery safety performance. For the commercial application of lithium-ion batteries, it is necessary to adjust the operation and management mode in the industry to meet the requirements of producing high-standard batteries. It is also the most important issue for my country, which accounts for 40% of the world’s sales of cathode materials. This is like why my country is a big manufacturing country rather than a strong manufacturing country. This phenomenon also exists in my country’s lithium-ion battery market and is quite serious.
