Mitsubishi Cable Industries, Ltd. has developed a thin light polymer battery whose performance does not deteriorate even at low temperature. Devising special electrolyte, the company maintained battery performance even at -30℃ or lower. The newly developed polymer battery is 6.2cm long, 3.5cm wide, and 3.8cm thick. The polymer battery developed features the smooth move of ions in electrolyte, which generates electric current, with the addition of special additives to the electrolyte and electrode. Due to this arrangement, it is easier for the battery to generate electric current even at -30℃ or less. Conventional polymer batteries tend to lose performance at -10℃ or less, and to stop generating power in most cases at -20℃. Since the battery instantaneously generate 2.4A, double other manufacturers' products, it can be used as a large-capacity power supply. The company plans to cultivate demand for power supplies for cell phones, personal digital assistants (PDAs), and notebook computers that require stable reception and transmission of radio waves regardless of temperature.
