      Local symmetry is determined by four fundamental degrees of freedom, namely, lattice, charge, orbital, and spin. The main properties of energy storage materials, especially those of batteries, are capacity, electric poten- tial, rate, and reversibility. They are determined by structures defined by the above‐mentioned fundamental degrees of ...

These coordinates are called generalized coordinates when they are independent of each other. Thus system with two degrees of freedom will have two equation of motion and hence has two frequencies.
