Electrochemical energy storage technology route

What is electrochemical energy storage (EES) technology?

Electrochemical energy storage (EES) technology, as a new and clean energy technology that enhances the capacity of power systems to absorb electricity, has become a key area of focus for various countries. Under the impetus of policies, it is gradually being installed and used on a large scale.

How do electrochemical energy storage devices work?

The principle of operation of electrochemical energy storage devices is based on the formation of a chemical reaction between the electrolyte and the electrodes contained in it. Then there is a shortage of electrons on one of the electrodes and an excess on the other. This allows chemical energy to be converted into electrical energy.

Why is electrochemical energy storage important?

The main reasons for these results may be as follows: Firstly, technology maturity and commercial applications: Among existing energy storage technologies, electrochemical energy storage is the most widely applied . It has a higher degree of technical foundation and commercialization, which attracts more research interests and investment.

What is the construction of an electrochemical energy storage?

Construction of an electrochemical energy storage. As can be seen, typically electrochemical energy stores consist of two electrodes (anode, cathode). The anode is an electrode, where oxidation typically occurs, while the cathode is an electrode, where reduction occurs.

Why do we need a large-scale development of electrochemical energy storage?

Additionally, with the large-scale development of electrochemical energy storage, all economies should prioritize the development of technologies such as recycling of end-of-life batteries, similar to Europe. Improper handling of almost all types of batteries can pose threats to the environment and public health .

Will research on electrochemical storage reach its peak?

The publication volume of electrochemical storage has been exponentially increasing, indicating that research on electrochemical storage may reach its peak and enter a stable development phase in the near future.
