Breaking down the research and development status of solid-state batteries -Lithium - Ion Battery Equipment

Since the emergence of all-solid-state lithium-ion battery technology, researchers from various countries have expressed great interest in research. The research content has gradually extended from the initial battery charging and discharging principles to battery design, high-performance solid-state separator materials, etc. category, and many world-famous electronics companies such as South Korea's Samsung Electronics have also begun to organically combine all-solid-state lithium-ion battery technology with the smartphones, automobiles and other products processed by the company, and then fully tap the economic value and use value of the technology On the basis of realizing the commercial promotion of all-solid-state lithium-ion battery technology.

In terms of materials, teams represented by the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences and the Shanghai Institute of Ceramics of the Chinese Academy of Sciences have developed a series of oxide and sulfide powders, ceramic sheets, etc., and have begun to contribute to society. Supply samples and supplies. In the research related to bifunctional polymer electrolytes, the Institute of Chemistry of the Chinese Academy of Sciences has successfully developed a new bifunctional polymer electrolyte and implemented UV curing technology to prepare it. The high room temperature ionic conductivity and mechanical strength achieved can be used for room temperature solid lithium metal. ion battery.(Lithium - Ion Battery Equipment)

Japan: The basis of Toyota's all-solid-state batteries is the technology to reduce the internal resistance of solid-state batteries. With this technology, Toyota has increased the energy output density (by volume) of all-solid-state batteries to approximately 2.5kW/L. At the same time, the energy density was successfully increased to 400Wh/L, which is twice the energy density of lithium-ion batteries processed around 2010.

Germany: The German government has provided financial support for the research and development of solid-state batteries. German Chancellor Merkel plans to allocate 1 billion euros to support a battery processor in Germany and will also fund a battery research and development institution to develop the next generation of solid-state batteries.

United States: In October 2018, Fisker announced that its new solid-state lithium-ion battery takes only 9 minutes to charge and will be mass-produced. Since then, the company’s solid-state battery technology has received investment from heavy machinery manufacturer Caterpillar, but the exact amount of investment has not been disclosed. Fisker said the patent-pending Fisker flexible solid-state battery costs less than $100 per kilowatt hour and can be used in the construction, energy storage, transportation and mining industries. Commercialization is expected to occur between 2018 and 2033.
