Researchers from Japan have presented a new type of battery with a record-breaking capacity. It can be used in space or places with record low temperatures.
Hitachi Zosen has developed a semiconductor battery with record-breaking capacity and resistance to a wide temperature range. The device can be used in satellite and industrial technology.
The high-performance semiconductor battery, unveiled at the Tokyo show on Wednesday, 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.
With less risk of occurrence and higher energy efficiency than conventional lithium-ion batteries, semiconductor batteries are considered the next generation of energy. 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 Japan Aerospace Exploration Agency to test practical applications 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 testing will take place over six months.
Hitachi Zosen has already developed a technology for producing 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 semiconductor 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.
