Scientists have invented a unique battery for cars

A group of scientists from the Center for Battery Technology and Energy Storage has created a battery for cars that charges from the cold. The technology is based on a self-assembling layer of electro-chemically active molecules.

The media writes about this.

Engineering professor Donghai Wang spoke about the innovation. A self-assembled monolayer is an active component, and it decomposes into a number of substances and at the same time protects the surface of the lithium anode. In addition to it, the battery includes a lithium oxide cathode, there is an electrolyte, which is a mixture of lithium-ion materials, and a special protective layer of a thin film is also provided.



The task of scientists was the need to adjust molecular chemistry in order to self-assemble on the surface of a liquid. The nascent monolayer provides a stable electrolyte interface when charging in cold conditions. The layer is applied to a copper plate. When lithium hits the monolayer, it begins to actively decompose, with a certain amount of this element remaining on copper.

Along with this, a part of the original layer is restored. The capacity of the new batteries can be increased, scientists say. They are working to lengthen the life of the experimental battery, which is currently only capable of being cold charged a few hundred times.
