Summary: The study investigates the impact of host material porosity on the performance of Li-S batteries using a sulfur-rich copolymer as the cathode active ingredient. Two types of porous CNF samples were designed to study the effects, and it was found that using microporous CNFs led to stable capacity over a larger number of cycles compared to mesoporous CNFs. The research highlights the significant role of cathode host porosity in battery performance, despite the positive effect of C-S bond formation in the active material.

Summary: Polymeric conducting binders have significant research value as they can serve as both binders and conducting agents, increasing the proportion of active materials in batteries and the volumetric energy density. This study explores the potential of a composite of PEDOT:PSS and polyethylene glycol (PEG) as a high-performing binder for silicon anodes. The addition of PEG polymer enhances the conductivity of PEDOT:PSS and improves the mechanical properties of the silicon anode, resulting in extended cycle endurance. The use of operando optical microscopy allows for direct observation of the binder's operation. Consequently, the bifunctional PEDOT:PSS/PEG binder shows promise for high-performance lithium-ion battery binders.

Summary: Metal fluorides as conversion-reaction cathodes have advantages such as low cost, environmentally friendly, and high energy density. In this study, a hydroxyl-rich copper fluoride (Cu2(OH)3F) was proposed as a conversion cathode, coupled with an electrolyte additive engineering, to address the poor reversibility issue. The presence of OH in Cu2(OH)3F enables effective suppression of Cu+ dissolution, resulting in better reaction reversibility and kinetics.
