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;
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;
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;
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,
wherein the first negative pole portion of the first cell portion includes one or more coupling bolts,
wherein the first positive pole portion of the first cell portion, the second negative pole portion and the second positive pole portion of the second cell portion, the insulating layer, and the series connector have one or more through-holes, through which the coupling bolts extend, and
wherein coupling nuts are fastened to end portions of the coupling bolts fitted into the through-holes.
 
11. A vehicle comprising:
a vehicle body; and
a plurality of 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;
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;
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;
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,
wherein the series connector covers a surface of one side of the first cell portion,
wherein the series connector connects the first negative pole portion and the second positive pole portion in series by directly contacting the carbon fiber of the first negative pole portion and the second cathode active material,
wherein the first negative pole portion of the first cell portion includes one or more coupling bolts,
wherein the first positive pole portion of the first cell portion, the second negative pole portion and the second positive pole portion of the second cell portion, the insulating layer, and the series connector have one or more through-holes, through which the coupling bolts extend, and
wherein coupling nuts are fastened to end portions of the coupling bolts fitted into the through-holes.
