When it comes to alternate energy, SANYO is more than the leading manufacturer, it is a pioneer. In 1963, SANYO developed the CADNICA® Nickel Cadmium (Ni-Cd) battery, marking the beginning of the era of cordless electric products. SANYO was also a pioneer in bringing other rechargeables to the market including Lithium Ion, Lithium Polymer and Nickel Metal Hydride. SANYO developed amorphous silicon solar batteries in 1979 marking a major breakthrough in harnessing the power of the sun and solar energy. Since the first battery pack engineered in 1987, SANYO has produced more than 4 billion battery packs over past 20 years.
