Dataset for manuscript entitled "Insights into the LiMn2O4 Cathode Stability in Aqueous Electrolyte"

Dataset for manuscript entitled Insights into the LiMn2O4 Cathode Stability in Aqueous Electrolyte. This dataset includes: -XRD of as-deposited films and bare substrate -TERS average spectra and maps of the as-deposited and cycled samples -Macro-Raman spectra of the as-deposited and cycled samples. -PALS data of the as-deposited and cycled films, as a function of depth and extracted for 2 keV本数据集为题为《水性电解质中LiMn₂O₄正极稳定性探析》的学术论文配套数据。本数据集包含以下内容： - 沉积态薄膜与裸基底的X射线衍射（XRD）数据； - 沉积态与循环后样品的针尖增强拉曼光谱（TERS）平均谱及成像图谱； - 沉积态与循环后样品的宏观拉曼光谱； - 沉积态与循环后薄膜的正电子湮没寿命谱（PALS）数据，该数据随深度变化且提取自2 keV测试条件下的结果。
