Next-generation technology roadmap for lithium batteries -Lithium - Ion Battery Equipment
First of all, the development and production of batteries with low cobalt content or even no cobalt has become an important direction for the development of next-generation lithium batteries. For lithium battery manufacturers and car manufacturers, cobalt metal is expensive and has to be imported in large quantities from the Democratic Republic of Congo, so it is urgent to get rid of or reduce its dependence on cobalt. Companies including JohnsonMatthey and NanoOne have developed ways to reduce or even replace cobalt.(Lithium - Ion Battery Equipment)
Secondly, in order to reduce the charging problem faced by the large-scale promotion and application of new energy vehicles, lithium batteries with fast charging capability have also become an important research and development direction for automobile manufacturers and battery manufacturers. The Israeli battery company StoreDot is committed to this, and claims to have successfully developed a new type of battery that can fully charge a mobile phone in 60 seconds and a new energy vehicle in just a few minutes.
Again, major battery companies are still racing to launch high-energy-density batteries. One of the ways to achieve high energy density batteries is to replace the original graphite anode material with high energy density materials including silicon or metallic lithium. Two major battery companies in the United States, SilaNanotechnologies and Enovix, have developed silicon anode materials using different methods. South Korea's Samsung SDI is focusing on the development of a silicon and graphite composite material called "graphene spheres".
In addition, solid-state batteries are also expected to achieve high energy density, good safety, and long cycle life. The technical core of solid-state batteries lies in the selection and application of electrolyte materials. Therefore, we use the electrolyte material system as the classification basis, and select three types of electrolyte material systems, namely, mixed solid-liquid electrolyte, inorganic electrolyte and solid polymer electrolyte, for specific analysis of solid-state batteries. Although these three types of solid-state battery systems have good prospects, it will take time to usher in large-scale development and application.
