Supercapacitors (also referred to as electric double-layer capacitors (EDLC), electrochemical capacitors, electrochemical supercapacitors, and ultracapacitors) are a class of energy storage devices that bridge the gap between electrolytic capacitors and rechargeable batteries. Supercapacitors can typically store 10 to 100 times more energy per unit volume or mass than their … [Read more...]
Lithium-Ion Battery Option for DIN Rail Industrial UPS
