Development of Lithium-Ion Batteries "Semi-Solid Batteries" Using Special Polyethers
OsakaSodaCO.,LTD. Development＆Commercialization Div.
Our gel-like electrolyte using special polyether not only possesses high flexibility and elasticity but also combines lithium-ion conductivity equivalent to that of liquid electrolytes and high moisture retention. When used in semi-solid batteries, the suppression effect of gas generated from the decomposition of the electrolyte (a resistance component within the battery) enables longer battery life and rapid charging. Furthermore, it dramatically enhances safety by preventing thermal runaway due to overcharging or short circuits. In the future, we will establish a supply system for the mass production of semi-solid batteries, while also advancing practical development for further performance improvements, miniaturization, and scaling up, targeting a wide range of industrial applications from consumer electronics such as wearable devices to automotive batteries that require high safety standards.
