Nonaqueous electrolyte battery having wound electrode structures |
摘要 |
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. <IMAGE> |
