Roughly the size of a postage stamp, the PC-10 ultracapacitor from Maxwell Technologies Inc. (San Diego, CA) has a proprietary electrode for enhancing the reliability of backup power in enterprise storage and powering smart utility meters, among other applications.

The PC-10 provides up to ten years of reliable data protection for high-performance solid-state drives (SSD) and non-volatile memory modules in enterprise storage systems, in the event of power disruptions. The PC-10 can also aid in load-sharing arrangements, powering meters to transmit data from residences who have agreed to lower their energy use during peak periods.

Ultracapacitors store energy in an electric field rather than through the chemical reactions of conventional batteries. With an extremely high energy density, ultracapacitors provide an independent, instantly available source of power unaffected by temperature, shock, overcharging, and millions of discharging/recharging cycles.

The PC-10's proprietary electrode provides tighter capacitance and resistance control for more precise charging times and more efficient discharge.
