Launch of large prismatic supercapacitors and modules in sample quantities

CAP-XX is pleased to announce that it has commissioned a small-scale production line to manufacture the GC1 supercapacitors and GC6 modules for evaluation, following the recently announced completion of Laboratory testing and in-vehicle trials of its automotive modules. This will facilitate further research by customers and potential licensees.

Global demand for high energy, high power supercapacitors (ultracapacitors, electric double layer capacitors or EDLC) is growing rapidly as new applications come to market. These include Stop-Start and Kinetic Energy Recovery Systems (KERS) for cars, trucks, buses, cranes, construction machinery and elevators, ride-through power for trams and trains, uninterruptable power supplies, renewable energy management, power factor correction and on-grid/off-grid storage.

CAP-XX, which has long been recognised as a leader in small supercapacitor markets, has now developed a large prismatic supercapacitor for use in these emerging applications, together with a proprietary supercapacitor management system for multi-cell modules operating at higher voltages. The critical success factors for these products are size, weight, energy and power. This translates to a need for high energy density (thousands of Farads in the smallest possible device) and high power density (very low series resistance in a very efficient package). CAP-XX meets these requirements first by using the most advanced materials available inside the cell, and then by packaging them in an extremely efficient prismatic cell. This combination of best in class materials and packaging delivers energy and power density ratings for CAP-XX which are more than double those of competitive products.

Notes to editors

Why supercapacitors?

Because they do things batteries can't. And they do it in a package that weighs less, takes up less space, and has negligible environmental costs. They deliver the high currents demanded by peak loads like engine cranking in Stop-Start systems, accept the high currents and rapid recharge generated during coasting and braking in micro-hybrid vehicles, run for millions of cycles, and will do it all at temperatures that leave batteries cold - even down to an Arctic -40°C.

CAP-XX, has long been recognised as a leader in small supercapacitor markets, has now developed larger prismatic supercapacitors for use in these emerging applications, together with the electronics necessary to package them efficiently into higher voltage modules and interface them to energy sources and loads. The key requirements for a category killer in these markets include high energy density (capacitance in the thousands of Farads, stored in the smallest possible device), and high power density (very low series resistance, and very efficient packaging). These requirements are met in part by the advanced materials used by CAP-XX in its electrodes, electrolytes and separators, but are also supported by the prismatic design of its supercapacitor cells. These thin, flat devices offer as much as 30% greater packaging efficiency internally than an equivalent cylindrical supercapacitor, and a further 10% or more when stacked into multi-cell modules for higher voltage applications. 

About CAP-XX

CAP-XX (LSE:CPX) is a world leader in the design and manufacture of thin, flat supercapacitors and energy management systems used in portable and small-scale electronic devices, and to an increasing extent, in larger applications such as automotive and renewable energy. The unique feature of CAP-XX supercapacitors is their very high power density and high energy storage capacity in a space-efficient prismatic package. These attributes are essential in power-hungry consumer and industrial electronics, and deliver similar benefits in automotive and other transportation applications.
