Extreme temperature conditions are required to generate this form of energy, thus limiting its utility . Electrochemical energy storage systems (EES) utilize the energy stored in the redox chemical bond through storage and conversion for various applications.
Factors governing the electrochemical energy storage capability of an electrode As stated earlier, in order to store energy electrochemically, reservoirs for ions and electrons are needed. Materials with a certain composition, structure, and morphology have the capability to hold charged particles, and hence to store energy electrochemically.
