The rechargeable battery is one of the main elements of the electric car. It is a source of electricity needed to power the motor (s). The topic of the report is entirely focused on nickel-metal hydride batteries, as well as trends in their development.

The electric battery is a chemical source of current, whose main specificity is the reversibility of internal chemical processes. This ensures its repeated cyclic use (by charge-discharge) for energy storage and autonomous power supply of various electrical devices and equipment, as well as for providing backup energy sources in medicine, manufacturing, transport and other fields.
