　　Why do many companies focus on battery research and development? The market position may change in the next 5 years!

　　Toyota focuses on solid-state batteries

　　There was a topic some time ago that Toyota's new energy three-wheelers could not distinguish between cars and motorcycles. On October 22, Toyota Executive Vice President and Chief Technology Officer Shigeki Terashima told the media that Toyota is equipped with the latest solid-state battery technology Electric vehicles will meet global consumers at the Tokyo Olympics next year. Currently, new energy passenger vehicles generally use battery liquid cooling technology, such as Tesla and BMW Toyota new energy vehicles. This platform is developed All products are purely electric and equipped with autonomous driving functions. Nissan, Toyota, and Honda have teamed up with Tada to develop solid-state battery technology for electric vehicles, which is currently the most advanced in the world. Currently, in order to eliminate consumers' concerns about vehicle range , most car companies are using lithium-ion batteries with higher energy density, so that lithium-ion batteries can further improve the driving range of electric vehicles.

　　Lithium-ion battery density continues to increase

　　As the density of lithium-ion batteries increases little by little, safety risks have become the most noteworthy. Although most people widely believe that solid-state batteries have the advantages of high safety and high energy density, they are only positive. R&D speculation, only when its mass-produced products show absolute advantages can lithium-ion battery manufacturers truly replace ternary lithium-ion batteries. In the field of solid-state batteries, Toyota has always adhered to an internal R&D strategy. The largest The advantage lies in its power performance. The Xenia R7 new energy version is equipped with a maximum power of 80kw. The battery energy density is expected to reach 300~400Wh/kg or even higher. The energy storage device is equipped with ternary lithium with a battery energy density of over 150wh/kg. Compared with the liquid lithium-ion batteries currently on the market, solid-state batteries use solid electrolytes, which are non-flammable, non-corrosive, non-volatile, and have no leakage problems. They have high energy density, small size, and support for fast charging. It has effectively dispelled consumers' current anxiety about battery life and energy replenishment. The two parties announced that they will work together to actively explore the field of automotive battery technology in the future and conduct in-depth cooperation on the research and development of next-generation new energy batteries for car companies.

　　The era of electrification may arrive early

　　According to statistics from battery research institutions, by 2025, the energy density of solid-state batteries will rise to a very high level, resulting in a significant reduction in cost. The popularization of high-end products to low-end products is an inevitable trend. Judging from this timetable, the trend of solid-state power lithium batteries is about to arrive. Global car companies will also accelerate their entry into this industry and start a battle for position in advance. In this global war for solid-state batteries , Toyota, which was the first to come up with finished products, can be regarded as a preemptive move. Battery technology is undoubtedly the tray for the development of pure electric vehicles, and the move towards solid-state is the general trend of lithium-ion batteries. It will also become the accelerated development of products of major domestic and overseas car companies. A catalyst for electrification, helping car companies accelerate their move into the electrification era.

　　Judging from Toyota's advancement speed, its lithium-ion batteries seem to have taken the lead in the global competition for solid-state batteries.
