We report on the fabrication of a robust hybrid film containing MnO2 for achieving large areal capacitances. An agarose gel, as an ion-permeable and elastic layer coated on a current collector, plays a key role in stabilizing the deposited pseudocapacitive MnO2. Cyclic voltammetry and electrochemical impedance spectroscopy data indicate that the hybrid electrode is capable of exhibiting a high areal capacitance up to 52.55 mF cm(-2), with its superior structural integrity and adhesiveness to the current collector being maintained, even at a high MnO2 loading.
我们报告了一种稳健的混合薄膜的制备，其中包含 MnO2 以实现大的面电容。琼脂糖凝胶作为涂覆在集流器上的离子可渗透和弹性层，在稳定沉积的赝电容 MnO2 方面起着关键作用。循环伏安法和电化学阻抗谱数据表明，即使在高 MnO2 负载下，该混合电极也能够表现出高达 52.55 mF cm(-2) 的高面电容，同时保持其对集流器的优异结构完整性和粘附性。
