摘要 |
This present invention addresses problems such as increase in contact resistance, loss of flexibility, and increase in weight if a metal electrode or the like is used when producing a flexible secondary battery by using an organic conductive material. Organic conductive materials of the same type or different types whereof the charge carrier density can be controlled are used to prepare two organic conductive materials having different charge carrier densities, and these organic conductive materials are connected solely through an electrolyte wherein a proton may diffuse in order to produce a rechargeable and flexible secondary battery using no electrodes such as of metal or carbon constituting a positive electrode or a negative electrode, and requiring no auxiliary agent or process such as material surface processing. |
