WRL Technologies Inc. - High energy density, solid-state supercap storage

SOLID-STATE

HIGH ENERGY DENSITY CAPACITOR BASED STORAGE TECHNOLOGY

WRL Technologies Inc. is enabling electrification and decarbonization by setting new benchmarks for performance of storage technology, delivering
the widest operating temperature range, degradation-free capacity, fastest charging speeds (without affecting life or capacity),
highest energy density, best safety, lowest cost, longest life and the most environmentally sustainable.

Chemical Batteries (Liquid or Solid-State) Will Not be Good Enough

Chemical batteries are limited by the science of electro-chemical storage. Their performance degrades in real-world temperature ranges (they only perform adequately in the limited range of 0°C to 35°C*).

Their capacity constantly degrades with use, therefore a used vehicle (or boat or plane) market will never develop. They can never be charged quickly, even 15 minute charge times are harmful and reduces cycle life. They are always oversized to handle high rate-of-discharge (e.g. when an EV is accelerating), so they will always be bulky even with advances in energy density.

Since they contain chemicals, the risk of igniting will never go away. To overcome all these challenges, they will always be expensive. And finally, because of their chemical construct, they degrade with use so their life is always going to be limited and they will most likely always be a net pollutant.

Solid-State Capacitor Based Storage
Now Enables Electrification and Decarbonization

Electrification and decarbonization require performance which is beyond the scope of chemical batteries, both solid-state and liquid. There is a need for high charging/discharging speeds, for multiple cycles a day, for operations in very high and very low temperatures, for consistent capacity over life, for low-maintenance and safe operation under these demanding conditions at an affordable cost and at scale.

WRL Technologies solid-state, high energy capacity capacitor-based storage meets these demanding requirements – it is non-chemical, has 1.5x the energy density of existing chemical cells, has 4 – 10x longer life than chemical / solid-state batteries, does not degrade with cycling, is safe, is environmentally sustainable and recyclable, operates in a very wide temperature range, has abundant availability of raw materials and has the lowest cost in the industry.

It has easily the longest life of any storage technology in the market, under real-world conditions.

It’s non-degrading attribute delivers consistent and predictable capacity over its life cycle, enabling consistent range and a used asset market to develop.

Its non-chemical attribute makes it the safest storage option, under all conditions, in the industry.

Its electrostatic attribute makes high-charge speeds without degradation possible, bringing down charge times to less than 6 minutes for a 0%-100% charge cycle.

Its flexible form factor allows it to be cut and formed into a variety of shapes, enabling it to be deployed as structural storage, i.e. storage as the casing.

With an energy density of 360Wh/kg today and expectations of 450Wh/kg within the next six months, it delivers the highest energy density in the industry.
