A non-aqueous electrolyte battery having improved low temperature characteristics and preservation characteristics. The non-aqueous electrolyte battery includes a negative electrode containing a carbon material as a negative electrode active material, a positive electrode containing a positive electrode active material and which is arranged facing the negative electrode and a non-aqueous electrolyte arranged between the negative and positive electrodes. The negative electrode contains a material not doped with lithium and/or not emitting lithium in an amount of not less than 20 wt% and not larger than 40 wt% based on the negative electrode active material.
Abstract:
Disclosed herein is a fuel cell which utilizes the biogenic metabolism to produce a high current density. It generates electric power in such a way that the fuel is decomposed stepwise by a plurality of enzymes and those electrons formed by oxidation are transferred to the electrode. The enzymes work such that the enzyme activity of the enzyme involved in decomposition in the early stage is smaller than the sum of the enzyme activities of the enzymes involved in decomposition in the later stage. In the case where a coenzyme is involved, the enzyme activity of the oxidase that oxidizes the coenzyme is greater than the sum of the enzyme activities of the enzymes involved in the formation of the reductant of the coenzyme, out of the enzymes involved in the stepwise decomposition of the fuel.
