Electrochemical energy storage is based on systems that can be used to view high energy density (batteries) or power density (electrochemical condensers).
Abstract. Electrochemical capacitors (EC) also called ''supercapacitors'' or ''ultracapacitors'' store the energy in the electric field of the electrochemical double-layer. Use of high surface-area electrodes result in extremely large capacitance. Single cell voltage of ECs is typically limited to 1–3 V depending on the electrolyte used.
Modern human societies, living in the second decade of the 21st century, became strongly dependant on electrochemical energy storage (EES) devices. Looking at the recent past (~ 25 years), energy storage devices like nickel-metal-hydride (NiMH) and early generations of lithium-ion batteries (LIBs) played a pivotal role in enabling a new
