A LiCoO2 battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge, and reversely when charging. Different types of lithium-ion batteries use different chemistry and have different performance, cost, and safety characteristics. Unlike lithium primary batteries (=disposable batteries), lithium-ion cells use an intercalated lithium compound as the electrode material instead of metallic lithium.
LiCoO2 batteries are one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses for consumer electronics, Li-ion batteries are growing in popularity for defense, electric vehicles, and aerospace applications due to their high energy density.
The three primary functional components of a lithium-ion battery are the anode, cathode, and electrolyte. The anode is made from carbon, the cathode is lithium cobalt oxide, and the electrolyte is a lithium salt in an organic solvent.
The three participants in the electrochemical reactions in a lithium-ion battery are the anode, cathode, and electrolyte.
Both the anode and cathode are materials into which, and from which, lithium can migrate. When a lithium-based cell is discharging, the lithium is extracted from the anode and inserted into the cathode. When the cell is charging, the reverse process occurs: lithium is extracted from the cathode and inserted into the anode.

In a lithium-ion battery the lithium ions are transported to and from the cathode or anode, with the transition metal, cobalt (Co), in LixCoO2 being oxidized from Co3+ to Co4+ during charging, and reduced from Co4+ to Co3+ during discharge.

Nickel-metal hydride cells have an anode (negative) in a metal alloy capable of absorbing and desorbing hydrogen, plus a nickel hydroxide cathode (positive), immersed in an alkaline electrolyte solution of potassium, sodium and lithium hydroxides. Nickel-metal hydride cells are rechargeable and deliver a voltage of 1.2 V.
The cells are maintenance-free but require precise charge level monitoring, to control gaseous exchanges with the outside and thus water consumption (for open cells, only slightly pressurized, owing to size). Charge monitoring also helps minimize heating under charge, to maximize capacity and service life. Sealed cells are in cylindrical shape with nickel steel can. They are used in many mobile and fixed professional and industrial applications.

Nickel-cadmium cells have an anode (negative) in cadmium hydroxide and a cathode (positive) in nickel hydroxide, immersed in alkaline solution (electrolyte) comprising potassium, sodium and lithium hydroxides. The cells are rechargeable and deliver a voltage of 1.2 V during discharge.
MINAMOTO and have been making nickel-cadmium batteries for over 16 years, addressing a huge variety of professional and industrial applications, with different capacities. Sealed cells are cylindrical in shape, in nickel-steel cans.
Nickel-cadmium batteries have a legendary reputation for robustness, reliability and service life. This is the benchmark technology for difficult and demanding applications: operating temperatures from -40C to +60C (because the electrolyte has a very low freezing point), excellent cycling capability (up to 3,000 cycles), long storage life, and low or zero maintenance.
The chemical reactions in a NiCd battery during discharge are:
