The Japanese battery giant recently announced that they have successfully developed a new solid-state battery with a capacity of 25 times that of traditional lithium-ion batteries. This breakthrough technology is expected to revolutionize electric vehicles, mobile devices, and more. It is reported that samples of this new solid-state battery will be shipped as early as January this year.
A solid-state battery is a type of battery that uses a solid-state electrolyte that has a higher energy density, longer lifespan, and faster charging speed than traditional liquid lithium-ion batteries. However, due to the poor conductivity of solid-state electrolytes, the energy density and charge-discharge performance of solid-state batteries currently on the market are still not comparable to those of liquid lithium-ion batteries.
The Japanese battery giant has successfully solved the problem of poor conductivity by using a new solid-state electrolyte called "gel polymer" in this research and development. It is reported that this gel polymer is a composite material composed of a polymer network and a liquid electrolyte, which has high conductivity and excellent chemical stability. With this new electrolyte, the Japanese battery giant has succeeded in achieving a significant increase in the capacity of solid-state batteries.
It is understood that the energy density of this new solid-state battery has reached 300 watt-hours per kilogram, which is 25 times that of traditional lithium-ion batteries. This means that the new solid-state battery can provide a longer range for electric vehicles or a longer period of life for mobile devices at the same weight. In addition, this battery has a faster charging speed and can charge 80% in just 10 minutes.
In addition to its high energy density and fast charging characteristics, the new solid-state battery has a longer lifespan. Since the solid-state electrolyte is not prone to chemical reactions, the service life of the battery can be extended to more than 10 years, which is much higher than the life of traditional lithium-ion batteries. This will help reduce the maintenance costs of electric vehicles and mobile devices, further promoting sustainability in these areas.
The Japanese battery giant said it plans to start providing samples of the new solid-state battery to customers in January this year and gradually achieve mass production over the next few years. They are already working with several automakers and electronics manufacturers to develop products based on the new solid-state battery.
This breakthrough technology will revolutionize areas such as electric vehicles and mobile devices. With the growing global demand for renewable energy and low-carbon mobility, high-performance, low-cost solid-state batteries will become the key technology and market competition focus in the field of energy storage in the future. The leading position of Japanese battery giants in this field will undoubtedly win more opportunities and advantages for them in the future market competition.
