Energy harvesting

Posted on

Electrochemical processes show a unique interaction with the surrounding environment. In particular, the interactions of the electrical double-layer with the environment allow us to tap into (1) chemical concentration energy and (2) thermal gradients. By this way, we can use interfacial electrochemistry for energy harvesting.
