Hitachi Zosen has developed a semiconductor battery with record-breaking capacity and resistance to wide
High performance semiconductor battery,unveiled Wednesday at the Tokyo show, it has a capacity of 1,000 milliampere-hours - about seven times the Japanese company's previous models. It can also operate in a temperature range of 100 to minus 40 degrees Celsius.
Less risk and higherenergy efficiency than conventional lithium-ion batteries, semiconductor batteries are considered the next generation energy source. Japan's Toyota Motor and Murata Manufacturing are leading semiconductor technology manufacturers, but they still face challenges such as increasing capacity and reducing development costs.

The company has already reached an agreement with the JapaneseAgency for Aerospace Research on testing the practical application of semiconductor batteries in space. The camera equipment, powered by a Hitachi Zosen battery, will be shipped to the national Kibo module on the International Space Station this fall and will be tested over a six-month period.
Hitachi Zosen has already developed the technologythe production of solid electrolyte without the use of a sealant or solvent. Using fewer impurities reduces electrical resistance, improving battery performance.
Despite the fact that the new semiconductorthe battery has reached a record capacity, it still lags far behind its lithium-ion counterparts. The ones used in smartphones offer performance in the thousands of milliamps per hour.
