3. Jin Yulong
The research and development of the company's solid-state battery project has been promoted in an orderly manner, and the solid-state electrolyte and semi-solid-state battery have entered the pilot test: the wholly-owned subsidiary and Jin Tianyi * * * have jointly developed technologies related to solid-state batteries, and their research team has accumulated research foundation in the field of lithium-ion batteries for more than 20 years, and successfully mastered the research results such as macro preparation of oxide solid-state electrolyte, mass production of silicon-carbon anode materials, and in-situ integration of solid-state batteries.
Solid state battery principle
The traditional liquid lithium battery is also called "rocking chair battery" by scientists. The two ends of the rocking chair are the positive and negative electrodes of the battery, and the electrolyte (liquid) is in the middle. Li-ion, like an excellent athlete, runs back and forth at both ends of the rocking chair. During the movement of lithium ion from the positive electrode to the negative electrode and then to the positive electrode, the charging and discharging process of the battery is completed.
The principle of solid-state battery is the same, except that its electrolyte is solid, and its density and structure can make more charged ions gather at one end and conduct more current, thus improving the battery capacity. Therefore, with the same amount of electricity, the volume of solid-state batteries will become smaller. Moreover, since the solid-state battery has no electrolyte, it will be easier to seal. When used in large equipment such as automobiles, there is no need to add additional cooling pipes and electronic control, which not only saves the cost, but also effectively reduces the weight.
