Japanese company TDK claims to have made significant progress in developing small solid-state batteries. The company says it has developed a material that makes it possible to make batteries with an energy density of 1,000 Wh/L.
The company agrees press release This technology could be used to replace button cell batteries. These are the small disc-shaped batteries used in watches, calculators and hearing aids. Current lithium-ion batteries have a higher energy density Between 300 and 700 watts/litre. TDK plans to send samples to customers next year, and then hopes to start mass production.
However, this technology is not suitable for larger batteries, such as those used in electric cars or smartphones. Kevin Chang, senior research analyst at data firm Wood Mackenzie, told the newspaper Financial Times. As these batteries get larger, they become more fragile, according to Zhang. According to the analyst, this is inherent in the materials used.
A solid-state battery is a type of rechargeable battery in which the electrolyte consists entirely of a solid material, unlike traditional batteries that use liquid or gel electrolytes. Benefits include increased energy density and improved safety due to the absence of flammable liquids. Disadvantages currently include high production costs and challenges in extending service life.
