UNIVERSITY FILE GRAPHENE SUPERCAPACITOR PATENT
April 19, 2017
Vancouver, B.C. New York, NY – Graphene Energy Storage Devices Corp. (GESD), 40% owned
by Lomiko Technologies, a 100% owned subsidiary of Lomiko Metals Inc. (“Lomiko”) (TSX-V:
LMR, OTC: LMRMF, FSE: DH8B) , is pleased to announce the successful completion of a
development project undertaken jointly with the Research Foundation of Stony Brook University
(SBU) has been completed with a new patent filing by Stony Brook University.
The SBU team lead by Dr. Samuilov discovered a novel method for assembly of high -voltage
Supercapacitor units. GESD and SBU recently filed a U.S. provisional patent application to protect
the technology. The SBU team assembled and tested a 10 V Supercapacitor energy storage unit,
thus proving feasibility of the high-voltage design. This development opens avenue for new low-
cost energy storage products. Curr ently, GESD is working on scale -up of the technology and an
in-field evaluation of the energy storage unit.
The Largest Manufacturers of Supercapacitors are Maxell Technologies, Elna America, AVX
Corporation, Panasonic Electronic Components, Taiyo Yuden, NessCap Co Ltd., Nichison, United
Chemi-con, Cornell Dublier Electronics, Cooper Bussman, Kemet, Rubycon and there are over 300
varieties of Supercapacitors in a growing market for these devices.

Supercapacitors are promising energy storage devices. Due to their fast charge -discharge
characteristics, low equivalent series resistance, long cycle life, wide operating temperatures,
supercapacitors are finding application in transportation, industri al and grid energy storage.
There is rapidly growing demand for capacitive energy storage systems with high power and
energy densities. However, individual supercapacitor units have very low stand -off voltage, < 3
V. In order to increase the operation volt age to a practical level, > 3 V, the EDLCs are connected
in series stacks. The EDLCs need to be interconnected and balanced with an electronic circuit,
which results in a bulky and expensive energy storage system.
The GESD-SBU team demonstrated design and implementation of a sealed high -voltage EDLCs
energy storage unit. The unit is internally balanced, there is no need for an external circuit. The
electrode is very cost -effective 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.
About Graphene ESD
Graphene ESD is developing energy storage based on graphene platelets. High surface area and
outstanding electrical conductivity of graphene enable devices with a unique combination of fast
charge/discharge and large stored energy. Our devices utilize grap hene platelets manufactured
from high-quality natural graphite by a low -cost scalable process. Graphene ESD is 40% owned
