e=1/2
cU 2,
cfor ratio capacitance,
ufor rated operational voltage) depend on the character of electrode active material and electrolyte.Electric field activated form capacitor utilizes to have certain interlamellar spacing (d
002) graphite material contact with electrolyte, apply normal when using the voltage of more than voltage, electrolyte is inserted embeds graphite crystal interlayer, electric field activation occurs, obtains electric field activated form capacitor, thus show higher electrostatic capacitance.Once embed electrolyte ion to form pore in graphite material, then under operating voltage, Reusability also keeps high static capacity thereafter.Organic salt dissolvent electrolytic solution is the electrolyte that electric field activation capacitor the most often adopts, the stable rated operational voltage < 3.0V of quaternary ammonium salt organic solvent electrolyte, at short notice also can at < 4.0V operating at voltages, therefore, the topmost electrolyte system of electric field activated form ultracapacitor is become.But common organic salt (as quaternary ammonium salt) is solid at normal temperatures, when using as electrolyte, must be dissolved in organic solvent, therefore, ion concentration and withstand voltage properties increase rate limited.

CN101194328A discloses one " electrode for electric double layer capacitor and double charge layer capacitor ", and this capacitor is with class graphite microcrystal charcoal for electrode active material, and two spiro quaternary ammonium salt cations of enclosed construction are BF to anion
4 -, PF
6 -deng being electrolyte for electrolytical organic solvent, under 2.7V ~ 4.0V voltage, carry out electric field activation.Two spiro quaternary ammonium salt of enclosed construction have the ion volume less than open-chain structure and the electrochemical stability of Geng Gao, can obtain the chemical property higher than non-close structure quaternary ammonium salt.Its shortcoming is: 1, the electrolyte ion of solvation has larger ionic radius, be unfavorable for its graphite layers carry out slotting embedding-move out; 2, organic solvent is easily polymerized under high electric field activation voltage, and at the polymer film that graphite surface is formed, blocking electrode active material aperture, makes the reduction of capacitor ratio capacitance, efficiency for charge-discharge declines, internal resistance increases.
