Copper-coated Porous Polyimide as Ultralight and Safe Current Collectors for Advanced LIBs

引用

Chinese Journal of Polymer Science 2024年第4期42卷 521-531页

作者： Cun-Sheng Liu Jun-Qi Hu ting-ting mao Song-Yi Liao Ru-Ming Feng Yi-Dong Liu Yong-Gang Min School of Materials and Energy Guangdong University of TechnologyGuangzhou510006China College of Chemistry and Chemical Engineering Zhongkai University of Agriculture and EngineeringGuangzhou510225China Shanwei Branch of Advanced Energy Science and Technology Guangdong Laboratory Shanwei516600China

Metallic copper is widely used as current collector(CC) for graphite anode of lithium-ion batteries(LIBs) due to its high electrical conductivity and electrochemical stability. However, the large volume density of commercial copper foil(~8.9 g·cm^(-3)) limits the increase of energy density of battery. Here, copper-coated porous polyimide(Cu@PPI) was prepared by vacuum evaporation as collector for the graphite anode. The sandwich structure connects the copper metal on both sides of the collector with excellent electrical conductivity. Compared to commercial Cu foil, Cu@PPI has lighter mass(≤3.9 mg for disc of 12 mm diameter versus 9.9 mg of ~10 μm Cu foil) and lower volume density(≤3.3 g·cm^(-3)). In addition, the porous structure allows of better adhesion of reactive substances and electrochemical properties than pure Cu foils. It is estimated that the energy density of Cu@PPI should be much higher than that of Cu foil. This strategy should be applicable for other current collectors.

为实现通过提高癌前病变分类准确率,以降低结直肠癌的发生率和死亡率,提出一种基于MMTS-AdaBoost的高维数据分类算法,优化高维数据分类算法,提高分类性能。通过将本征正交思想引入马田系统,构建改进马田系统获取重要特征变量实现降维。使用降维得到的特征,应用AdaBoost算法对癌前病变类型进行分类。实验结果表明,与使用降维处理的mrmr-AdaBoost和chisquare-AdaBoost算法,以及AdaBoost、BP网络、NB、SVM等经典分类算法相比,MMTS-AdaBoost的F1和G-mean更高,分类性能更优。
