Dual-ion batteries(DIBs), a novel energy storage technology wherein both anions and cations actively participate in the electrochemical redox process, hold great promise for further cost reduction in chemical energy storage. Organic materials have garnered significant attention as cathode materials for DIBs due to high working voltage, exceptional rate capability, environmental friendliness, and unique designable structure. This review provides a detailed discussion of the energy storage mechanism and typical characteristics of organic cathode materials from various reaction active sites. This work also highlights the current limitations and proposes ideas for improvement. Finally, potential future directions for the advancement of DIBs are summarized.

为研究球体垂直入水空泡的演化过程,基于N-S方程、VOF多相流模型及动网格技术,对球体的垂直入水过程开展了数值仿真模拟并进行分析。球体入水初期受到较强的冲击载荷并产生喷溅,球体入水后会产生和大气相连的入水空泡,空泡形成之后,依次经历发展、闭合以及溃灭等演化阶段,空泡受到的周围流体压力是空泡发生深度闭合的主要原因,空泡在闭合后会产生上下两股高速射流。结果表明:数值计算得到的球体垂直入水空泡形态和试验结果吻合良好,验证了仿真的准确性。

In order to enhance the spectral characteristics of the laser-induced breakdown spectroscopy(LIBS), the spectral signals of soil samples with different concentrations of KCl and KI additives were analyzed. The optimal laser energy, the lens to sample distance(LTSD) and the delay time were determined. Under the optimum experimental conditions, the spectral intensity, signal-to-noise ratio(SNR) and plasma characteristics of Cd I 288.08 nm and Al I 394.40 nm in soil samples with 0%, 5%, 10%, 15%, 20%, 25% and 30% KCl and KI additives were analyzed. The experimental results show that the spectral intensities of Cd and Al in soil samples with 15% KCl are 1.33 times and 1.61 times of that of the original sample, while those with 15% KI are 1.84 times and 1.81 times. The SNR, plasma temperature and electron density are improved. This provides an experimental reference for improving the accuracy of LIBS in soil detection.
