| titleOfInvention | Ultracapacitor spiro quaternary ammonium salt and preparation method thereof |
| abstract | The invention discloses a kind of ultracapacitor spiro quaternary ammonium salt and preparation method thereof, it is characterized in that, general formula is:n wherein: n, m=1 in (A), 2,3; (B) or (C) in n, m=1,2,3; P=1,2.Preparation method comprises: take water as reaction medium, under the effect of alkali, by cyclic amine and saturated dihalide or glycol disulfonic acid ester, through condensation reaction; Gained spiro quaternary ammonium salt and di-oxalate lithium borate are carried out ion-exchange, more purifiedly namely obtains object product.Raw material of the present invention is easy to get, good reaction selectivity, and quality product is high, is suitable for large-scale production, the ultracapacitor that described spiro quaternary ammonium salt is formed, and has low internal resistance and high electrostatic capacity, and excellent cycle characteristics. |
