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.

Abstract: A nonaqueous electrolyte battery which is capable of minimizing damage if the battery is crushed with pressure is disclosed. The nonaqueous electrolyte battery according to the present invention incorporates: a spirally coil formed by, through a separator, winding a positive electrode which incorporates an elongated positive-electrode collector having two sides on each of which an active material for the positive electrode has been formed and a negative electrode which incorporates an elongated negative-electrode collector having two sides on each of which an active material for the negative electrode has been formed, wherein the positive electrode has a lengthwise directional end which has two sides each of which is provided with a positive-electrode-collector exposed portion in which a positive-electrode collector is exposed, the negative electrode has a lengthwise directional end which has two sides each ofwhich is provided with a negative-electrode-collector exposed portion in which a negative-electrode collector is exposed, and the positive-electrode-collector exposed portion and the negative-electrode-collector exposed portion cover the coil one or more times through the separator.
