“A cell is a single electrochemical source of electrical potential, or voltage. They come in numerous sizes and chemical types, both of which directly determine the cell’s nominal capacity and voltage rating, respectively.”
“Primary and secondary batteries are simply batteries that can be used one time or more than one time, respectively; primary meaning “once” and secondary meaning “twice.” A rechargeable battery (secondary) can be used more than once and a non-rechargeable battery (primary) can only be used once.”
“Lithium based cells and batteries can be made up of numerous and various chemical compositions. The specific chemical composition will first determine whether the battery is rechargeable or not. Secondly, each composition has a particular benefit in the attribute areas of capacity, energy, energy density, specific energy, maximum discharge rate, number of useful cycles, inherent safety and/or cost.”
“All cells and batteries, being electrochemical sources of electrical potential, can only maintain that electrical potential for as long as the chemicals that create that potential exist inside the battery.”
