CR2430 battery manufacturers predict that solid-state lithium batteries will become the technical direction of future CR2430 battery development.

　　CR2430 battery manufacturers predict that solid-state lithium batteries will become the technical direction of future CR2430 battery development. Solid-state CR2430 battery is a new battery technology that can not only meet the energy density requirements of charge and discharge, but also take into account safety, cycle life, service life and other performances. Will solid-state lithium batteries become the technical direction of CR2430 battery development in the future? In this article, the CR2430 battery manufacturer will analyze it for you.

　　CR2430 battery manufacturers predict that solid-state lithium batteries will become the technical direction of future CR2430 battery development.

　　Lithium batteries can be divided into four categories according to their electrolytes: liquid, semi-solid, quasi-solid, and all-solid. Solid-state lithium batteries are extremely safe due to the fact that the solid-state electrolyte is non-flammable, non-corrosive, non-volatile, and does not leak. It can also overcome the lithium dendrite phenomenon.

　　In comparison, my country's research in the field of solid-state lithium batteries started relatively late, with patent applications mainly starting in the late 1980s. In recent years, as the market share of my country's power battery industry has continued to expand, the patent protection awareness of relevant innovation entities has gradually increased. Since 2011, the number of patent applications in this field has increased dramatically. Among the top 10 domestic applicants for patent applications in this field, 8 are from universities and research institutes, and 1 is from a domestic and foreign enterprise, including Fudan University, Central South University, Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences and other scientific research institutions. It is the main R&D institution for this technology in my country.

　　Due to its difficulty in overcoming the high resistance characteristics of solid electrolytes and some problems in functional density, it is temporarily difficult to commercialize it in batches. It can be seen that electrolyte materials are the core of all-solid-state CR2430 battery technology and will largely determine performance parameters such as power density, cycle stability, safety performance, high and low temperature performance, and service life of solid-state lithium batteries.

　　Since solid-state batteries are recognized in the industry as being able to increase the energy density of existing CR2430 battery systems and have high feasibility in terms of safety and cycle life, they have attracted the favor of many domestic and foreign R&D institutions. It is understood that there are currently more than 20 automobile manufacturing companies, universities and research institutes around the world dedicated to research related to solid-state battery technology.

　　Solid-state lithium batteries have high energy density and safety that are unmatched by current lithium batteries. Currently, more than 50 manufacturing companies, start-up companies and research institutions around the world are engaged in the research and development of solid-state lithium batteries. Companies in European and American countries and regions have entered the field of solid-state lithium batteries by acquiring and investing in start-up companies.

　　CR2430 battery manufacturers believe that in the process of industrialization of solid-state lithium batteries, my country should increase capital investment, encourage technological innovation, actively promote school-enterprise cooperation, accelerate the transformation of research results, learn from the advanced experience of Japanese and Korean companies, and encourage power battery industry entities Formulate a reasonable patent layout strategy, strengthen overseas patent layout, and achieve catch-up in solid-state CR2430 battery technology through investment and acquisitions.

　　How are solid-state lithium batteries better than lithium batteries?

　　From the perspective of technology development potential, it is relatively difficult to increase the energy density of ternary lithium batteries, while all-solid-state lithium batteries have more potential to increase the energy density. There are 3 main reasons:

　　1. The voltage platform of all-solid-state lithium batteries has been greatly improved, and solid electrolytes have a wider electrochemical window than organic electrolytes, which is conducive to further improving battery energy density;

　　2. The solid electrolyte can block the growth of lithium dendrites, improve the scope of material application systems, and lay the foundation for new CR2430 battery technology with higher energy density space.

　　3. The current energy density of all-solid-state lithium batteries is about 400Wh/Kg, and the estimated maximum potential value can reach 900Wh/Kg, with more than 100% room for improvement. However, it is difficult for ordinary ternary lithium batteries to increase the battery energy density to more than 300Wh/Kg.

　　Research on solid electrolytes at home and abroad mainly focuses on three major categories of materials: polymers, oxides and sulfides. Polymers have good high-temperature properties and have been used in individual commercial applications; oxides have good cycle performance and are mostly used in lithium batteries with thin-film flexible structures; sulfides have the highest conductivity and may be solid-state The main future direction of lithium batteries.
