Graphene ESD has announced the successful completion of its development project, undertaken jointly with the Research Foundation of Stony Brook University (SBU), that explored a novel method for assembly of high-voltage supercapacitor units.

The team assembled and tested a 10 V supercapacitor energy storage unit, thus proving feasibility of the high-voltage design. This development opens the door for new low-cost energy storage products. Currently, GESD is working on scale-up of the technology and an in-field evaluation of the energy storage unit.

The GESD-SBU team demonstrated design and implementation of a sealed high-voltage EDLC energy storage unit. The unit is reportedly internally balanced, with no need for an external circuit. The electrode is made of nano-carbon composite either of a commercial carbon or of graphene platelets with carbon nanotubes. The nano-carbon electrode materials were used for deposition and assembly of a working prototype of an internally balanced high-voltage energy storage unit. The bench-top prototype unit, tested up to 10 V, exhibited good discharge characteristics and charge retention. This development enables new compact energy storage solutions for grid and vehicular applications.

As part of the agreement, Graphene ESD provided $50,000 funding to the SUNY Research Foundation. The research took place at SBU campus, Stony Brook, NY.
