摘要： This invention provides a battery including a cylindrical battery case and an electrode group that is smaller than the battery case and is accommodated in the battery case, so as to effectively utilize the configurations of the battery case and the electrode group and achieve reliable contact between one of electrodes in the electrode group and the battery case. The battery includes a cylindrical battery case 2 and an electrode group 3 including a positive electrode 31, a negative electrode 32, and a separator 33. The electrode group 3 and an inner peripheral surface of the battery case 2 define a space communicated from a top to a bottom, and the negative electrode 32 has a current collecting terminal 321 that extends from the electrode group 3 in a direction away from a center axis of the battery case 2 and is in contact with a bottom surface 2B of the battery case 2.

摘要： According to the present invention, a battery includes: a cylindrical battery case; and an electrode body disposed in the battery case, and including a positive plate, a negative plate, and a separator disposed between the positive plate and the negative plate. A spacer formed of a dense body and an electrolyte storage space storing an electrolyte are provided between the electrode body and the battery case on one end or both ends of the battery case in an axial direction of the electrode body. Thus, a battery of high energy density and a long life, in which the unsteadiness of the electrode body in the battery case can be suppressed, can be provided at low cost.
