The opening of chemists will allow creating solid-state batteries with high energy density

Japanese chemists have developed a new complex hydride-lithium superion conductor, which will create fully solid-state batteries with the highest energy density today.

Solid-state drives can solve the main drawbacks of modern lithium-ion batteries, such as electrolyte leakage, flammability and limited energy density. The optimal anode material for them is a metallic Li, which has a maximum theoretical capacity (3860 mAh / g) and the lowest potential among well-known alternatives.

The problem is that most of the existing solid electrolytes are chemically unstable or poorly contaminated with lithium, which significantly reduces the performance of devices during repeated cycles. However, researchers from the University of Tokhoku managed to take a breakthrough in this direction.

They developed a new solid electrolyte with high ionic conductivity and stability with respect to metallic lithium under room temperature. The unique properties of the material are due to its structure consisting of two different hydrogen clusters (complex anions).

According to scientists, they expect that the complex hydride with superionic conductivity created by them will lead to the development of new electrochemical devices with high energy density indicators, and also stimulates new studies in this direction.

Toyota Motors and Panasonic are also studying this technology and have already agreed to establish joint production of solid-state batteries for cars whose container will be
