Graphene ESD to partner with Stony Brook to develop new low-cost integrated ultra-high voltage supercapacitors

Green Car Congress

Supercapacitors bridge the gap between conventional capacitors and rechargeable batteries. The goal of the project is the development of low-cost integrated ultra-high voltage supercapacitor units by a high-rate reel-to-reel process. Lomiko Metals Inc. currently owns a 40% stake in Graphene ESD and Mr. A. Earlier post.).

Rechargeable membrane-less hydrogen bromine flow battery shows high power density

Green Car Congress

MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. The rapid and reversible reaction kinetics of both the bromine reduction reaction and the hydrogen oxidation reaction minimize activation losses, while the low cost ($1.39 Credit: Braff et al.

Initial Results of UK EV Driver Study Show Increased Confidence and Low Cost Recharging

Green Car Congress

The average cost to trial participants for recharging at home is between 25p and £1 (US$0.40 Collecting real-world analysis of electric vehicles is essential in understanding actual demands and requirements of low carbon vehicles for consumers. The low cost of ‘refuelling’ in relatively short periods of time reinforce this.
