    CHARGEABLE:

    Nickel Cadmium Battery (NiCd)

    Created by Waldemar Jungner of Sweden in 1899 which was based on Thomas Edison’s first alkaline battery. Using nickel oxide hydroxide and metallic cadmium as electrodes. Cadmium is a toxic element, and was banned for most uses by the European Union in 2004. Nickel-cadmium batteries have been almost completely superseded by Nickel-metal hydride batteries.
    Voltage: 1.2V

    Nickel-Metal Hydride Battery (NiMH)

    First developed around 1980’s. The battery has a hydrogen-absorbing alloy for the negative electrode instead of cadmium.
    Voltage: 1.2V

    Lithium-ion Battery

    The technology behind Lithium-ion battery has not yet fully reached maturity. However, the batteries are the type of choice in many consumer electronics and have one of the best energy-to-mass ratios and a very slow loss of charge when not in use. The popularity of Lithium-ion batteries has spread as their technology continues to improve.
    Voltage: 3.6V

    Lithium Polymer Battery

    Unlike lithium-ion cylindrical, or prismatic cells, which have a rigid metal case, polymer cells have a flexible, foil-type (polymer laminate) case, but they still contain organic solvent.
    Voltage: 3.7V
