Russian scientists have found a way to triple the capacity of a lithium-ion battery
Researchers have synthesized a new anode material for a lithium-ion battery that triples capacity and extends battery life.
Lithium-ion batteries are currently the most widely used energy storage. Despite the years of development of this technology, the capacity of such batteries is still limited by ineffective graphite. – anode key material.
Recently, scientists from the National Research Technological University MISiS have developed a new material consisting of nanostructured microspheres Cu0.4Zn0.6Fe2O4. The anode made from it increases the capacity of the lithium-ion battery by three times and extends its effective life by 5 times compared to other alternatives..
To synthesize it, the team used a one-step spray pyrolysis method, in which the initial solution was turned into a fog, followed by the evaporation of water at 1200 °C and decomposition of the starting metal salts. As a result, porous micron or submicron spheres are formed..
We also previously reported on the invention of magnesium paste, which can store 10 times more energy than a regular battery..
