Camera batteries are essential for outdoor video capture and photography, for both surveillance and general use. But just how do these sources of power work and what are the eternal functions?
Essentially, most batteries contain three basic parts. Electrodes, an electrolyte and a separator. Within every battery are two electrodes, both of which are made of conductive material.
When a battery is powering a device like a camera, a series of chemical reactions occur in the electrodes. These are collectively known as oxidation-reduction (redox) reactions. These reactions result in the flow of ions between the anode and the cathode.
However, some of the most common batteries in use today are lithium-ion batteries, these power most consumer electronic devices. These batteries typically contain a carbon anode, a cathode made of lithium cobalt dioxide and an electrolyte containing a lithium salt in an organic solvent.
