Graphene supercapacitors created with traditional paper making process, rivals lead-acid battery capacity
2013-08-05 12:56:45| Extremetech
Materials engineers at Monash University in Australia have devised a method of producing graphene supercapacitors that have the same energy density as the lead-acid battery under your car's hood. Not only are these supercapacitors about 10 times more energy-dense than commercial devices, but the method of producing the graphene inside the supercapacitors seems to be novel as well. The engineers say they used a process that is similar to traditional paper making -- and that it could easily and cost-effectively scaled up for commercial production of graphene.

Valve Regulated Lead-Acid Battery has wide temperature range.
2013-05-30 14:29:08| Industrial Newsroom - All News for Today
QUINT UPS-IQ valve regulated lead-acid battery can operate under temperature shifts ranging from -40 to +60°C and in harsh environments. Pure lead absorbed glass mat (AGM) technology protects battery against acid spills while 5 hr buffer time maximizes performance. Lasting up to 10 yr, battery also lets users monitor performance such as State of Charge, State of Health, and State of Function for insight into repair or replacement needs.
