Scalable fabrication of sulfide SE membranes is the priority for mass production of ASSBs. However, due to the poor chemical stability of sulfide SEs, the wet-slurry-based preparation of sulfide SE membranes is still hindered by limited choices of solvent-binder systems. Herein, we reported a modified poly(vinylidene fluoride) (M-PVDF) binder to achieve environment-friendly fabrication of sulfide SE membranes. Copolymerization is firstly performed on the widely-used PVDF binder to decrease crystallinity, which facilitate excellent solubility in the isobutyl isobutyrate-based slurry. Utilizing this efficient M-PVDF binder, the sulfide SE membrane achieves a high ionic conductivity of 2 mS cm<sup>−1</sup> at 25 °C, an ultra-thin thickness of 26 μm, and good flexibility. The resulting ASSBs exhibit excellent rate performance with 53.51 % capacity utilization ratio at 5C. The ASSB also maintains high capacity retention rates of 96.9 % after 350 cycles under 0.5C at 25 °C and 87.8 % after 1000 cycles under 5C at 45 °C.

A hybrid WSO-RBFNN approach is proposed for the distribution network's photovoltaic (PV) fed electric vehicle charging stations. The performance of the proposed hybrid strategy is a combination of war strategy optimization (WSO) and Radial basis function neural network (RBFNN). It is hence referred to as the WSO-RBFNN technique. WSO optimizes the distribution network by minimizing power loss, improving voltage sensitivity, and reducing costs. Meanwhile, the RBFNN predicts the load demand. This innovative technique WSO-RBFNN identifies the nearest charging spots that minimize power loss and RBFNN optimizes power flow predicts charging demands and addresses both environmental and electrical grid stability concerns. The proposed technique is implemented in MATLAB. MATLAB is powerful computational software widely used in different fields like numerical computation, visualization, and algorithm development. MATLAB provides powerful tools for data visualization and plotting.

We also investigate the influence of SES on the electricity supply chain members.
