Solid-state lithium battery technology is expected to seize market opportunities

Solid-state lithium battery technology is expected to seize market opportunities. Currently, there are many market participants in the field of solid-state batteries. Automobile companies, battery companies, investment institutions, scientific research institutions, etc. play the game from three aspects: capital, technology and talents. As more and more companies join, the industrialization of solid-state lithium batteries continues to accelerate, and the commercial application of solid-state batteries is expected to accelerate. Companies that are the first to deploy related technologies are expected to seize market opportunities. Solid-state lithium battery technology is expected to seize market opportunities. Lithium-ion batteries will remain the best choice for electricity, consumer electronics and small and medium-sized energy storage in the near future. Silicon-based systems are the first choice for 300Wh/kg battery systems. However, Japan, the United States, and China, the three major battery producing countries, have successively set research and development goals for high-energy-density batteries, hoping to demonstrate prototype devices with an energy density of 400 to 500 Wh/kg and achieve quality development in 2020. . Production from 2025 to 2030. In order to achieve the goal of high energy density, all countries are actively developing and applying new battery technologies. China’s layout is ahead of schedule, and some companies have entered the trial phase of solid-state lithium-ion batteries (semi-solid batteries), and mass production of solid-state batteries may be realized in 2025. China began to deploy the solid-state battery industry as early as ten years ago. Many battery manufacturers are in a leading position in solid-state battery technology, and more and more companies are participating in solid-state battery research. Domestic car companies are cooperating with battery companies, and emerging electric car manufacturers are developing faster. It is estimated that by 2025, electric vehicles will be equipped with solid-state batteries. The new power of automobile manufacturing has emerged with its strong strength, multi-dimensional crossover and comprehensive innovation, and is in a leading position. Japanese and Korean companies are jointly developing, and Toyota plans to mass-produce electric vehicles equipped with solid-state batteries by 2022. Recognizing the huge potential of solid-state batteries, Japan started research and development very early. At present, the solid-state battery technology of Japanese companies around the world is in a leading position. South Korea's three leading battery companies have also chosen to jointly develop solid-state batteries. It can be seen that, regardless of whether it is a battery company in Japan or South Korea or an automobile company, on the basis of maintaining an independent Ru0026D team, most solid-state battery Ru0026D fields use 'group heating'. method. Advantages of solid-state lithium batteries 1. High safety performance: Compared with traditional lithium batteries, solid-state lithium batteries are less prone to short circuit, and the system temperature is relatively low, so the possibility of product explosion is low; 2. High energy density: solid electrolyte not only has Good electrochemical performance, small size, good stability, more high-voltage cathode materials can be installed, greatly improving the energy density; 3. Good cycle performance: after using solid electrolyte, the lithium battery is in the process of charging and discharging , There will be no SEI film (solid electrolyte interface membrane) and lithium dendrite phenomenon, which greatly improves the cycle and service life of the product; 4. It has the advantage of flexibility: solid lithium batteries can be prepared, because thin-film batteries and flexible batteries Flexible liquid electrolyte lithium batteries are easier to pack, safer, and can be used in smart wearable devices and implantable devices. Future medical equipment; 5. Higher energy density: The solid electrolyte has good physical properties, which can effectively suppress the short-circuit failure caused by the increase in the diameter of the lithium element, thereby prompting the use of metal electrodes with stronger theoretical capacity. The working voltage window of the solid electrolyte is wider, and the positive electrode material with stronger potential is used to distinguish the electrolyte solution. The shortcoming of'mileage anxiety' has become a major obstacle to the further popularization of new energy vehicles, and the existing lithium battery material system will soon hit the'ceiling' of energy density. Although domestic and foreign automakers and power battery companies are optimistic about solid-state batteries, the most optimistic in the industry is that solid-state batteries will not be commercialized until 2025, and the technology may be fully mature before 2030. The road to solid-state batteries is still a bit far away. For new energy vehicles and power battery companies, it is also necessary to find other new lithium battery material systems that can be commercialized more quickly. Lithium-sulfur batteries that combine high energy density, high theoretical specific capacity, low cost and environmental friendliness are an option. However, the 'shuttle effect' of lithium-sulfur batteries has been widely criticized and has been applied to the field of new energy vehicles without leaving the laboratory.
