BINDER SOLUTION FOR NON-AQUEOUS ELECTRO-CHEMICAL ELEMENT ELECTRODE, ELECTRODE FORMING AGENT, ELECTRODE, AND ELECTRO-CHEMICAL ELEMENT |
摘要 |
PROBLEM TO BE SOLVED: To stabilize performance for less degradation even if a material remains in an electrode, by using an organic solvent as a non-aqueous electrode binder with HOMO level and LUMO level from ab initio method molecular orbit calculation. SOLUTION: Related to an electric double layer capacitor, a separator 3 is sandwiched between two polarized electrodes 1 and 2, which are sealed between a stainless steel cap 4 and a stainless can 6 containing an electrolyte 5 with a packing 7 in between. Related to an organic solvent constituting a non-aqueous electrode binder solution, an HOMO level from ab initio method molecular orbit calculation is -12 eV or below while an LUMO level is +0.4 eV or above. As a solution for electrolyte, propylene carbonate is common while a quaternary phosphonium salt and a quaternary ammonium salt is common as an electrolyte. |
