OptiXtal's technology represents a significant extension of Electric Double Layer Capacitor (EDLC)technology. EDLCs are also known as ultracapacitors or supercapacitors. Whereas batteries are good for energy storage, they tend not to be good for power storage. Supercapacitors excel at power storage. They have the ability to charge and discharge much faster than batteries. They have other advantages over batteries as well. Unlike batteries, supercapacitors are not sensitive to either high or low extremes of temperature, thus enabling them to perform efficiently in a much wider range of environments. And while the useful life of batteries is measured in hundreds, or at best a few thousands, of power cycles, the life of supercapacitors is measured in the hundreds of thousands or millions of cycles.
OptiXtal's patented technology further extends the advantages of supercapacitors in three ways. First, most supercapacitors on the market today have an inflexible, cylindrical form factor similar to batteries. OptiXtal's SuperXcaps come in thin, flexible foil packaging. Their rectangular form factor allows for more efficient packaging with fewer voids. And our thin form factor allows SuperXcaps to be easily stacked, either in series or parallel, to meet a wide variety of power requirements. Secondly, our technology provides greater power density than competitive offerings, in terms of both mass and volume, including those with form factors similar to ours, such as those of Cap-XX. Finally, the extremely low ESR (Equivalent Series Resistance) of our supercaps enables them to hold a charge longer than competitive offerings.

Can Sony Li-ion batteries recover market share?

Sony was once the leader in the lithium-ion "Li-ion" battery market. In 1991, it was the first in the world to commercialize them. It has focused mainly on compact batteries for PCs and mobile phones. The lithium-ion battery market continues to expand, driven by strong demand for mobile phones, PCs and now electric vehicles. For example, such batteries are seen in an increasing minority of pure electric forklift trucks and boats, in most off-road electric vehicles and in virtually all Autonomous Underwater Vehicles AUVs, electric aircraft and electric airships, not just in on-road electric vehicles from buses to trucks, cars and some e-bikes. Sony is noticeably absent from all this vehicle activity, despite Sony CEO Howard Stringer announced plans, in 2009, to enter the automotive battery business.

Two devices will replace lead acid traction batteries

It is like waiting for a bus. You wait and wait then two come at the same time. Alternatives to short lived, toxic lead acid traction batteries, with their indifferent performance, have been sought for over 100 years. Now both lithium-ion batteries and supercapacitors are near to replacing lead acid traction batteries in the many traction applications where they are still used.

Greatly enhanced supercapacitor

Researchers at The University of Texas at Austin's Cockrell School of Engineering have created a new porous, three-dimensional carbon that can be used as a greatly enhanced supercapacitor, holding promise for energy storage in everything from energy grids and electric cars to consumer electronics.

Electromobility has a new key enabling technology

Foreign manufacturers of electric cars in China can own only minority shares and they must surrender intellectual property on at least one of what the government considers to be the three key enabling technologies for e-mobility. These are batteries, motors and control electronics. In exchange, foreigners gain access to a market they hope will be large enough to create cash flow that can be repatriated if the dominant partner approves.

Towards more effective energy harvesting

Energy harvesting calls for collecting light energy from solar or photovoltaic cells, piezoelectric from pressure, kinetic energy from movement, or inductive energy from rotation or motion. This is what generates the low levels of current that make wireless sensors operational, and capturing and storing sufficient power for these applications is a challenge.
