LiNi0.4Co0.3Mn0.3O2 thin film electrodes are fabricated from LiNi0.4Co0.3Mn0.3O2 raw powder at room temperature without pretreatments using aerosol deposition that is much faster and easier than conventional methods such as vaporization, pulsed laser deposition, and sputtering. The LiNi0.4Co0.3Mn0.3O2 thin film is composed of fine grains maintaining the crystal structure of the LiNi0.4Co0.3Mn0.3O2 raw powder. In the cyclic voltammogram, the LiNi0.4Co0.3Mn0.3O2 thin film electrode shows a 3.9-V anodic peak and a 3.6-V cathodic peak. The initial discharge capacity is 44.6 μAh/cm2, and reversible behavior is observed in charge-discharge profiles. Based on the results, the aerosol deposition method is believed to be a potential candidate for the fabrication of thin film electrodes.
LiNi0.4Co0.3Mn0.3O2薄膜电极是在室温下由LiNi0.4Co0.3Mn0.3O2原料粉末制成，无需预处理，采用气溶胶沉积法，该方法比蒸发、脉冲激光沉积和溅射等传统方法更快、更简便。LiNi0.4Co0.3Mn0.3O2薄膜由保持LiNi0.4Co0.3Mn0.3O2原料粉末晶体结构的细晶粒组成。在循环伏安图中，LiNi0.4Co0.3Mn0.3O2薄膜电极显示出3.9 V的阳极峰和3.6 V的阴极峰。初始放电容量为44.6 μAh/cm2，在充放电曲线中观察到可逆行为。基于这些结果，气溶胶沉积法被认为是制造薄膜电极的潜在候选方法。
