1. A vehicle body member having a charging and discharging function, the vehicle body member comprising:
a first cell portion including a first negative pole portion made of carbon fiber and a first positive pole portion disposed to be in contact with a surface of the first negative pole portion, the first positive pole portion including a first cathode active material and a first solid electrolyte, with one or more first via holes penetrating the first negative pole portion and the first positive pole portion;
a second cell portion including a second negative pole portion made of carbon fiber and a second positive pole portion disposed to be in contact with a surface of the second negative pole portion, the second positive pole portion including a second cathode active material and a second solid electrolyte;
an insulating layer disposed between a surface of the first cell portion and a surface of the second cell portion and configured to insulate the first cell portion and the second cell portion from each other, the insulating layer having one or more insulating via holes configured to communicate with the first via holes provided in the first cell portion;
a reinforcing member disposed in at least a portion of the one or more first via holes, the one or more insulating via holes, and one or more second via holes;
a series connector connecting the first negative pole portion of the first cell portion and the second positive pole portion of the second cell portion in series via the first via holes and the insulating via holes;
a positive pole current collector connected to the first positive pole portion of the first cell portion; and
a negative pole current collector connected to the second negative pole portion of the second cell portion.
 
14. A vehicle comprising:
a vehicle body; and
a plurality if vehicle body members attached to the vehicle body, each of the vehicle body members comprising:
a first cell portion including a first negative pole portion made of carbon fiber and a first positive pole portion disposed to be in contact with a surface of the first negative pole portion, the first positive pole portion including a first cathode active material and a first solid electrolyte, with one or more first via holes penetrating the first negative pole portion and the first positive pole portion;
a second cell portion including a second negative pole portion made of carbon fiber and a second positive pole portion disposed to be in contact with a surface of the second negative pole portion, the second positive pole portion including a second cathode active material and a second solid electrolyte;
an insulating layer disposed between a surface of the first cell portion and a surface of the second cell portion and configured to insulate the first cell portion and the second cell portion from each other, the insulating layer having one or more insulating via holes configured to communicate with the first via holes provided in the first cell portion;
a reinforcing member disposed in at least a portion of the one or more first via holes, the one or more insulating via holes, and one or more second via holes;
a series connector connecting the first negative pole portion of the first cell portion and the second positive pole portion of the second cell portion in series via the first via holes and the insulating via holes;
a positive pole current collector connected to the first positive pole portion of the first cell portion; and
a negative pole current collector connected to the second negative pole portion of the second cell portion.
