摘要:
Lithium-manganese oxide batteries are known for their long-term storage capabilities, characterized by low impedance and high discharge capacity. This study aims to enhance these properties by optimizing key battery components. XRD analysis of MnO2 (MD) powder, heat-treated at 400 degrees C for 5 hours, revealed improved discharge capacity. In addition, hot-pressed polypropylene nonwoven separators with electrolyte absorption exceeding 67 mg successfully reduced after-discharge impedance with minimal capacity loss (0.96%-1.26%). Last, the use of electrolyte additives led to a significant reduction in impedance for commercial electrolytes X and Y, contributing to overall battery performance improvement.
