EEStor is a company based in Cedar Park, Texas, United States that claims to have developed a capacitor for electricity storage, which EEStor calls the 'Electrical Energy Storage Unit' (EESU). Key to the increased energy density of the device is not improved charge density, but dramatically higher operating voltages. The company claimed that the EESU stored more energy than lithium-ion batteries at a lower cost than lead-acid batteries used in gasoline powered cars. Such a device would revolutionize the electric car industry. Experts always said such claims were far from being realistic. The claims have been shown to be over 100 times less than what the technology is actually capable of. Canadian company Zenn Motor Company licensed EEStor's fictitious technology for small cars and thereby received $30 million from the equity markets. Investors were seeking a method to indirectly invest in EEStor's fictitious energy density. Zenn spent about one-third of the money it acquired on EEStor. After six years and multiple stock offerings by Zenn, Zenn's consultants finally demonstrated EEStor's energy density claims were false. Instead of suing EEStor for fraud, Zenn spent its remaining cash on buying a majority share of EEStor and changed Zenn Motor Company's name because the capacitors were not useful for powering cars. ==Claimed specifications== The claims are described in detail in two of the company's patents, and . The following is how the EESU is claimed to compare to electrochemical batteries used for electric cars: * No degradation from charge/discharge cycles 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「EEStor」の詳細全文を読む スポンサード リンク
