EEStor Overview

EEStor is a company based in Cedar Park, Texas, United States that has developed a superior type of capacitor for electricity storage, which EEStor calls 'Electrical Energy Storage Units' (EESU). The EEStor EESU is an integral part of the much anticipated ZENNergy drive-train. Its CEO and president is Richard Weir, who is also a co-inventor named on their principal technology patent.

According to its patent, these units will use high-purity barium titanate coated with aluminum oxide and glass to achieve a level of capacitance claimed to be much higher than what is currently available in the market. The claimed energy density of the prototype is 1 MJ/kg; existing commercial supercapacitors typically have an energy density around 0.02 MJ/kg, while lithium ion batteries are around 0.54–0.72 MJ/kg.«Less
