An electrochemical cell is a device able to either generate electrical energy from electrochemical redox reactions or utilize the reactions for storage of electrical energy. The cell usually consists of two electrodes, namely, the anode and the cathode, which are separated by an electronically insulative yet ionically conductive
Lithium-ion insertion materials, proposed by Whittingham in the mid-1970s as the active agent in the positive electrode, 7 added the first new strategy in decades (if not centuries) to the portfolio of battery-derived portable power. Electrochemical energy storage of the 21st century is similarly poised for a transition from the old to the new.
PNNL researchers are making grid-scale storage advancements on several fronts. Yes, our experts are working at the fundamental science level to find better, less expensive materials—for electrolytes, anodes, and electrodes.
