    摘要: Capacitors containing novel electrodes and electrolytes are described. One electrode composition comprises an oxide of Mn and Fe in a Mn:Fe molar ratio of 3:1 to 5:1. Another electrode composition comprises an oxide comprising Ni, Co, and Fe; wherein the Ni and Co are present in a Ni/Co molar ratio in the range of 0.5 to 2 and a Fe and Ni are present in a Ni/Fe molar ratio in the range of 1.0 to 10. The resulting capacitors can be characterized by superior properties. Methods of forming the electrodes from gels are also described. An electrolyte comprising a Li salt in a carbonate solution, wherein the carbonate solution comprises 10-30% ethylene carbonate and 70-90% propylene carbonate is also described.
