Yes. There are two superconducting properties that can be used to store energy: zero electrical resistance (no energy loss!) and Quantum levitation (friction-less motion). .
Storing energy by driving currents inside a superconductor might be the most straight forward approach – just take a long closed-loop superconducting coil and pass as much current as you can in it. As long as the. .
Quantum Levitation allows a superconductor to move freely without friction in a homogenous magnetic field. An object rotating at a certain speed has the kinetic energy of: I is a rotation inertia (the equivalent of the.

LiFePO4 batteries include several safety features such as thermal stability, built-in battery management systems (BMS) that prevent overcharging and short circuits, and robust chemical composition that resists degradation. [pdf]
Not all tool lithium batteries are universal. Each power tool is designed with specific battery requirements, including voltage and connector type, which means that 20V lithium batteries are not universally interchangeable across all brands and tools2. However, some brands are starting to produce universal or cross-compatible batteries that can work with devices from other brands3. Generally, cordless power tool batteries are tailored to work with tools of the same brand4. [pdf]
