Industry have thought about electrical energy storage in terms of the battery and lately the supercapacitor. That’s because there were only two ways we thought energy could be stored. Either, as a chemical reaction – a battery – or as a physical separation of charge – a supercapacitor.

But electrical energy storage is so much more than that. There is a myriad of ways we can store energy in a device and with the advent of Graphene we have been able to unlock some of these other methods.

A battery has internal resistance and very little capacitance to it. But now we are able to access different storage mechanisms in the devices we are building and using.

That’s why Edison doesn’t work on batteries or supercapacitors – Edison works on electrical energy storage devices (EESD) Our EESDs capture a range of storage mechanisms and can be tuned to behave more like a batteries (the type B EESD) or like capacitors (the type C EESD) but in reality they are entirely new devices that have behaviors that tends to battery or capacitor behavior.

This means our type C will take a fast charge and release it equally as fast – just like a capacitor and our type B charges little more slowly and discharges more evenly – just like a battery.

Graphene is the reason they can have so much more power in them and we can do this in a much smaller scale because we use graphene throughout the device, and because we use graphene throughout the device we can do it more efficiently and access other ways to store the energy in ways that hybridize batteries and capacitors.
