Abstract

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.
