Battery Types & Uses

Batteries are portable energy sources featuring three basic components – an anode, a cathode and an electrolyte. Their properties relate directly to their individual chemistries. For instance, the characteristic voltage of Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) cells is 1.2V, alkaline cells are 1.5V, and Lithium ion cells are 3.6V. Other features such as energy density/capacity, charge/discharge… Read more »

Power vs Energy

Energy storage devices may be broadly characterized by their energy density (energy stored per unit volume or mass) and by their power (how fast the energy can be delivered). Conventional capacitors have enormous power, but store only tiny amounts of energy. Batteries can store lots of energy, but take a long time to charge and… Read more »

The Supercapacitor Advantage

Each day brings a new technical innovations, and the demand for smaller, more portable and more functional electronics. This puts pressure on power supplies to be light and small, run for long periods of time (i.e., have lots of energy), and meet the demands of multiple high current loads (i.e., have a high power capability)….

Energy Storage Technologies

Batteries, fuel cells, capacitors, and supercapacitors are all energy storage devices. Batteries and fuel cells rely on the conversion of chemical energy into electrical energy. Capacitors rely on the physical separation of electrical charge across a dielectric medium such as a polymer film or an oxide layer. Supercapacitors rely on the separation of chemically charged… Read more »
