DGAP-News: Lomiko Metals Inc. / Key word(s): Miscellaneous Lomiko Technologies Subsidiary Graphene ESD and Stony Brook University File Graphene Supercapacitor Patent 19.04.2017 / 14:59 The issuer is solely responsible for the content of this announcement. Vancouver, British Columbia & New York, New York--(Newsfile Corp. - April 19, 2017) - Graphene Energy Storage Devices Corp. (GESD), 40% owned by Lomiko Technologies, a 100% owned subsidiary of Lomiko Metals Inc. (TSXV: LMR) (OTCQB: LMRMF) (FSE: DH8B) ('Lomiko'), 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. Currently, 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, industrial 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 voltage 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.
