Murata start volume production of double layer energy devices

Murata Manufacturing Co., Ltd. has begun mass production of low-resistance (m ohm level) electric double-layer energy devices in slim, compact packages.

Technology introduced by CAP-XX, an Australian component design and manufacturing firm and Murata business partner as of 2008, has led to volume production of electronic double-layer energy devices with low resistance (m ohm level) in compact, slim packages. Optimization of electrochemical systems, including the electrode structure, enables flexible charging and discharging from high to low output at a range of temperatures. By supporting momentary peak load, the components also level battery load and can drive high-output functions that are difficult for batteries alone.

Key features of the product include:
Low ESR (equivalent series resistance) on the mO level enables high-current, high-output charging and discharging
High peak voltage: 2.7 V per cell
Stable output characteristics in a broad range of operating temperatures: -30°C to +70°C
Slim, highly durable package
Swelling is controlled, making the product ideal for smartphones, tablet computers, or other slim devices

Applications as listed by Murata include:
Auxiliary power supply for LED flash units in digital cameras, camcorders, or mobile phones
Means of reducing battery load fluctuations by supporting peak output Means of controlling battery load fluctuations from GSM or audio output
Means of supporting peak output when driving small motors
Backup solution for SSDs or similar devices
Means of supporting peak output for USB bus-powered devices
In conjunction with a variety of power-generating elements, can be used as a maintenance-free power-storage element with a useful life exceeding 100,000 cycles
