リチウムイオンキャパシタの原理と開発動向

摘要

Lithium ion capacitor is a kind of hybrid capacitor. It is composed of high specific surface area activated carbon cathode, anode such as intercalation carbon or lithium titanate that are able to dope and de-dope lithium ion and organic electrolyte containing lithium salt. It is operated at higher cell voltage than electric double-layer capacitor and has large energy density as well as high power density.%高出力での充放電が可能な二次電源としては，リチウムイオンニ次電池に代表される二次電池と，電気二重層キャパシタに代表される電気化学キャパシタがある．
