Self-supporting thick electrode base material and preparation method and application thereof
The invention provides a self-supporting thick electrode base material and a preparation method and application thereof. The self-supporting thick electrode base material is of an integrated porous self-supporting structure. The self-supporting thick electrode base material comprises a high-molecular polymer main body material, and a metal oxide and active sites are loaded on the high-molecular polymer main body material. According to the invention, when the provided self-supporting thick electrode base material is applied to a lithium battery, the electrochemical performance of a thick electrode is improved. In the high-temperature reduction preparation process, by utilizing a special gas atmosphere and temperature adjustment conditions, the compactness and thickness of wafer layer stacking can be regulated and controlled in appearance, the crystalline phase and the structural aperture size of the metal oxide can be regulated and changed microcosmically, so that the self-supporting thick electrode base material has excellent electrochemical energy storage performance.
本发明提供了一种自支撑厚电极基体材料及其制备方法和用途，所述自支撑厚电极基体材料为一体式多孔自支撑结构，所述的自支撑厚电极基体材料包括高分子聚合物主体材料，所述的高分子聚合物主体材料上负载有金属氧化物和活性位点。在本发明中，提供的自支撑厚电极基体材料应用于锂电池中，提升了厚电极的电化学性能，其中通过在高温还原制备过程中，利用特殊气体氛围和调节温度条件，表观上能够调控圆片层堆叠的紧密程度和厚度，微观上能够调控和改变金属氧化物的晶相和结构孔径尺寸，使得自支撑厚电极基体材料具有优异的电化学储能性能。
