specific Embodiment approach 1
[0020] Specific embodiment 1: The method of this embodiment to improve the electrode stability of water-based electrolyte batteries and water-based electrolyte capacitors is specifically modified with flexible graphite paper or conductive polymers in secondary battery systems or capacitors in which an aqueous solution is used as the electrolyte. The graphite-based material is used as the current collector to support the active material of the electrode material.
[0021] In this embodiment, the water-based electrolyte battery refers to a battery that uses an electrolyte solution composed of water as a solvent as the electrolyte; a water-based electrolyte capacitor refers to a capacitor that uses an electrolyte solution composed of water as a solvent as the electrolyte.
[0022] In this embodiment, ultra-thin flexible graphite paper or conductive polymer modified graphite material is used as the positive and negative current collector materials for water-based electrolyte batteries a...
specific Embodiment approach 2
[0023] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the aqueous solution refers to a solution formed by dissolving lithium, sodium, magnesium, zinc, and copper sulfate, chloride, nitrate, or chlorate in water. Others are the same as the first embodiment.
specific Embodiment approach 3
[0024] Embodiment 3: This embodiment is different from Embodiment 1 or 2 in that the secondary battery system refers to a sodium ion battery, a lithium ion battery, a magnesium ion battery, a zinc ion battery, or a copper ion battery. Others are the same as the first or second embodiment.
