[0002] In the irradiation process of the aqueous solution system in the self-supporting electrode preparation process, in order to improve the yield, isopropyl alcohol needs to be added as an oxidative free radical scavenger in the aqueous solution system, and the added isopropyl alcohol can be oxidized or radiolyzed into a small amount of by-products such as CH3COO- and CH3. The by-products can be adsorbed on the surface of the powdery active material, covering the active sites. In addition, when the powdery active material is used to build an electrode, a binder (Nafion, PTFE or PVDF reagent) needs to be added to improve the stability. The addition of the binder can increase the resistance of the electrode and cover the active sites, greatly reducing the electrochemical performance of the electrode active material.

[0003] At present, in order to improve the electrochemical performance of the powdery active material, a highly conductive self-supporting substrate is directly added to the solution system, so that the active material can grow in situ on the self-supporting substrate, but the active material is difficult to grow uniformly on the conductive self-supporting substrate.
