In Russia, the power and capacity of lithium-ion batteries have been increased

Russian scientists have improved cathode materials for lithium-ion batteries. This made it possible to increase their power and energy consumption.

For the batteries, experts used materials that are analogs of the olivine-group mineral – triphilin (LiFePO4). This mineral itself is more usable than the more common lithium cobaltite. However, the crystal structure of triphilin contains many defects. Russian scientists studied them and, thanks to this, created samples of cathode materials with improved properties.

As a result, they managed to achieve an increase in power density by at least 40 times, and energy intensity by 15%.

Lithium-ion batteries are widely used in modern household electronic equipment, including smartphones, laptops, etc. Such products are used even in electric vehicles.
