It's a high energy
density, 3.7V battery that is not compatible with ordinary batteries,
but is widely used in the portable equipment market. It uses
lithium metallic oxide in its positive electrode (cathode) and
carbon material in its negative electrode (anode), and the lithium
ions inside the battery transfer between the positive electrode
and the negative electrode during charge or discharge.
Features
High voltage
of 3.7V lets you cut down on the number of batteries you use.
High energy density
minimizes battery size and weight, making it perfect for use
in small portable equipment.
No metallic lithium
is used so charging and discharging are very safe.
