East power electronic devices will sell all solid battery to U.S.
East power electronic devices from July 20, 2010 to start selling the U.S. Infinite Power Solutions (IPS) of all solid batteries “THINERGY” (Figure 1). East power electronic devices and IPS signed a sales agency agreement, plans in Japan, Korea and Taiwan to sell. Tokyo Electric Power electronic devices and strive to achieve in the next three sales of 1 billion yen.
IPS’s all solid battery cathode material used in lithium cobalt oxide (LiCoO2), anode materials used in lithium metal films used in the solid electrolyte in lithium-phosphate oxygen and nitrogen (LiPON). Cell stack 6 by the coating layer electrode, the thickness of only 0.17mm.
Ongoing production of 1 inch (25.4mm) square units “MEC101″, with a capacity of 0.7mAh of standard products, as well as capacity 1mAh the end product. When the depth of discharge (DOD) to 100%, repeated 1C charge and discharge, still have 10 000 times more than life. The high rate at 70C discharge under the continuous release of 40mA of current (Figure 2). Self-discharge rate is only 1% or less. Operating temperature range is -40 ~ 85 ℃. Learned, is currently being developed for automotive use, etc. to support maximum working temperature of 260 ℃ products.
IPS plans to use these features, the new products for wireless sensors, active RFID tags, smart cards and other small medical devices inside the power supply system, and replace the portable battery built into the button and double-layer capacitors. East power electronic devices that exist on the market in particular, the following requirements: the batteries and solar cells and solid vibration power generation portfolio of small power modules for sensor networks, wireless sensor.
In addition to industry has begun to explore the board for power and standby power SSD memory in addition there will be solid battery built into the print wiring base plate for development. IPS provides not only solid battery monomer, also started to provide the solid battery with integrated charge management, over-charging protection and power regulation functions of the control circuit of the small power module (Micro Power Module, MPM).
Although the sample of solid battery price is 2000 yen, but once the IPS overall mass production and bring costs down to single digits. IPS Colorado in the United States to build an annual output of 1 million cell production system, after expansion may produce six million.
Can be mass produced unit in addition to MEC101, there are 1 inch × inch (50.8mm)’s “MEC102″ and 1 inch × 0.5 英寸 (12.7mm)’s “MEC120″, a total of three. In addition, from the fourth quarter of 2010, start sample shipments in the watch can be equipped with the 0.5-inch square “MEC125″.
IPS was founded in 2001, venture firms. From Oak Ridge National Laboratory (Oak Ridge National Laboratory, ORNL) won all solid battery technology licensing. In addition to IPS, the United States Cymbet and STMicroelectronics (STMicroelectronics) from Oak Ridge National Laboratory received a technology licensing.
