FDK and Asahi Kasei today concluded a basic agreement to establish a joint-venture company for the combined operation of a lithium ion capacitor (LIC) business.
The LIC is a next-generation energy storage device which allows rapid charging and discharging at high current. It features higher cell capacity than conventional electric double-layer capacitors (EDLCs) and longer life than lithium-ion batteries (LIBs). A large market for LICs is forecasted to develop beginning in 2015, as they contribute to energy conservation through more efficient use of electric power.
Identifying the LIC as a growth product, FDK has been a pioneer in its development and established a mass production system which enables integrated manufacture from LIC cells through complete modules. Asahi Kasei advanced work on the LIC based on its established technology for LIB materials, and successfully developed a high-performance LIC with low internal resistance which is ready for commercialization.
In recognition of the advantage of combining FDK's cell and module technology and production technology with Asahi Kasei's unique basic cell technology, the two parties concluded today's basic agreement for the establishment of a joint LIC business which will further strengthen R&D and supply capabilities.

IDTechEx notes that these devices are generically supercabatteries, less often called bacitors or Assymmetric Electrochemical Double Layer Capacitors. For now they are small devices for electronic circuits but alternatives to traction batteries are expected later. Elon Musk, founder of Tesla, believes that supercapacitors and their variants are the future of traction batteries. Sinautec has electric buses running on supercapacitors alone but they need recharging every few kilometers. Thus the need to combine the battery and supercapacitor techniology to get more acceptable range and vastlysuperior charge discharge speed and life of over 20 years - at least double that of today's lithium-ion traction batteries.
