首先以壳聚糖为起始原料,通过羧甲基化处理,显著提升了其水溶性。随后,利用LiOH进行预锂化,并引入双丙酮丙烯酰胺(DAAM)和乙二酸二酰肼(ADH),成功制备了具有出色自交联性能的粘结剂CDD-Li^(+)。为了探究这一粘结剂的结构特性,采用了傅里叶变换红外光谱(FT-IR)技术进行了表征。在粘附性方面,通过180°剥离实验,验证了CDD-Li^(+)的强粘附能力。利用电化学工作站对电池进行了循环伏安曲线的测试。结果显示,CDD-Li^(+)粘结剂所制备的电池能够发生高效的电化学反应,展现出卓越的电化学性能。与常用的聚丙烯酸(PAA)粘结剂相比,CDD-Li^(+)粘结剂在电化学性能上表现更为出色,展现出其在电池领域上的巨大潜力。通过蓝电电池测试仪,进一步研究了电池的倍率性能、循环性能以及锂离子扩散系数,并计算了电池的首圈库伦效率(ICE)。结果显示,CDD-Li^(+)粘结剂制备的电池不仅拥有更优的倍率性能和循环性能,其锂离子扩散系数平均高达10-10数量级,ICE也高达95%。与PAA粘结剂相比,CDD-Li^(+)粘结剂在硅碳负极中展现出更优秀的性能。

This paper is concerned with controller design of net- worked control systems （NCSs） with both network-induced delay and arbitrary packet dropout. By using a packet-loss-dependent Lyapunov function, sufficient conditions for state/output feedback stabilization and corresponding control laws are derived via a switched system approach. Different from the existing results, the proposed stabilizing controllers design is dependent on the packet loss occurring in the last two transmission intervals due to the network-induced delay. The cone complementary lineara- tion （CCL） methodology is used to solve the non-convex feasibility problem by formulating it into an optimization problem subject to linear matrix inequality （LMI） constraints. Numerical examples and simulations are worked out to demonstrate the effectiveness and validity of the proposed techniques.

The prediction of Remaining useful life(RUL) and the estimation of State of health(SOH) are extremely important issues for operating performance of Lithium-ion(Li-ion) batteries in the Battery management system(BMS). A multi-scale prediction approach of RUL and SOH is presented, which combines Wavelet neural network(WNN) with Unscented particle filter(UPF)model. The capacity degradation data of Li-ion batteries are decomposed into the low-frequency degradation trend and high-frequency fluctuation components by Discrete wavelet transform(DWT). Based on the WNN-UPF model, the long-term RUL of Li-ion batteries is predicted with the low-frequency degradation trend data. The high-frequency fluctuation data and RUL prediction results are integrated effectively to estimate the short-term SOH of Li-ion batteries. The experimental results show that the proposed method achieves high accuracy and strong robustness, even if the prediction starting point is set to the early stage of Li-ion batteries’ lifespan.

为计算配有常用抗冲切钢筋(箍筋和栓钉)的钢筋混凝土(RC)板柱节点的受冲切承载力,结合梁斜拉破坏机理和修正压力场理论(MCFT)提出一种配有抗冲切钢筋的RC板柱节点的受冲切承载计算方法.首先根据MCFT推导出配有抗冲切钢筋的RC板柱节点的临界斜裂缝倾角计算式;然后,假定冲切破坏时临界截面周长范围内的抗冲切钢筋达到屈服强度,将临界斜裂缝倾角代入MCFT推导出板柱节点的受冲切承载力计算方法;最后,使用该方法和美国规范(ACI 318-19)方法计算62个配有抗冲切钢筋的RC板柱节点试验的冲切承载力,并分析了混凝土强度、板有效厚度、柱截面边长、抗弯钢筋配筋率及抗冲切钢筋配筋率对节点抗冲切承载力的影响.结果表明:由MCFT推导出的节点受冲切承载力计算值与试验值吻合较好,均值为0.96,变异系数为0.20;节点的冲切承载力与上述影响因素呈非线性正相关.该方法可用于配有抗冲切钢筋的RC板柱节点的受冲切承载力计算.
