This chapter describes the basic principles of electrochemical energy storage and discusses three important types of system: rechargeable batteries, fuel cells and flow batteries. A rechargeable battery consists of one or more electrochemical cells in series.
Electrochemical energy storage systems have the potential to make a major contribution to the implementation of sustainable energy. This chapter describes the basic principles of electrochemical energy storage and discusses three important types of system: rechargeable batteries, fuel cells and flow batteries.
For electrochemical energy storage, the key parameters are specific energy and specific power. Other important factors include the ability to charge and discharge a large number of times, retain charge for long periods, and operate effectively over a wide range of temperatures.
Electrochemical energy storage/conversion systems include batteries and ECs. Despite the difference in energy storage and conversion mechanisms of these systems, the common electrochemical feature is that the reactions occur at the phase boundary of the electrode/electrolyte interface near the two electrodes .
Batteries are suitable for electrochemical energy storage, but only for limited periods of time due to their self-discharge property and aging, which results in a decreasing storage capacity. For electrochemical energy storage, the specific energy and specific power are two important parameters.
