Based on the advantages of safety and energy density, solid-state batteries are recognized as the main direction of the future development of power batteries, it is also the layout focus of new energy vehicle companies. On August 22, NIO signed a strategic cooperation agreement with ProLogium Technology, the two parties will jointly build a prototype vehicle using the ProLogium MAB solid-state battery pack and further cooperate on the production and application of solid-state batteries.
In recent years, many automakers have revealed plans to build electric vehicles based on solid-state batteries. For example, “Fisker applied for a solid-state lithium battery patent, the maximum range of 800km, charging for 1 minute”, “Volkswagen plans to develop a 1000km solid state battery” and other news are not uncommon. Although there is no specific timetable for mass production loading, but from the reaction of car companies, especially EV startups, its acceptance of solid-state batteries is relatively high, it is hoped that the cutting-edge technology path will break through the bottleneck of new energy vehicles.
NIO’s layout in core technology fields such as power batteries has always been “daringly aggressive”. In order to achieve higher energy density and longer cruising range, NIO ES6 has become the first model of CATL NCM811 battery, the density is 170Wh/kg. NCM materials can be divided into NCM111, NCM523, NCM622, NCM811, etc., the latter number represents the ratio of the three materials, high nickel can bring higher energy density, but it will also lose thermal stability. The existing liquid lithium ion power battery system is difficult to balance performance and safety, therefore, the exploration of the next generation of power battery technology has become the choice of many car companies.
It is understood that the party that cooperated – ProLogium Technology has been cultivating the solid oxide route for many years, and replaced the separator and electrolyte with the ceramic electrolyte of the oxide system to develop a lithium ceramic battery. Initially, ProLogium’s first “Flexible Lithium Ceramic Battery” (FLCB) was used primarily as a small-capacity solid-state battery for consumer electronics and wearables. After years of experience in the field of consumer solid-state batteries, ProLogium began to switch to the larger market for the power battery market and developed a high-voltage lithium-ceramic battery (BLCB). Before the cooperation with NIO, ProLogium Technology also reached a cooperation with Enovate Motors in the solid-state battery business during the Shanghai Auto Show in April 2019.
In fact, both China and other countries, including battery companies, materials companies, and car companies are actively deploying solid-state battery industrialization. As a new type of lithium battery for high-performance systems, solid-state batteries still face many challenges in industrialization, including the need to complete the supply chain and system supply, and the production equipment and technology must be built from a new system. Globally, all solid-state batteries are expected to begin mass production between 2020 and 2025. In this process, there are still many basic scientific research and process technology problems to be broken, and gradually improve the existing lithium battery to meet the challenges of energy density and safety.
