Summary: A Co-doped MnO2 nanorod network layer with oxygen vacancies was self-assembled on a commercial separator through the chemical growth method to improve the performance of lithium-sulfur batteries (LSBs). The modified separator effectively alleviated the shuttle effect and accelerated the redox conversion of polysulfides. Additionally, it demonstrated superior thermostability and flame-retardant properties. This strategy provides a new route for designing durable and efficient LSBs.

Summary: The study synthesized four different MnO2 polymorphs with controlled morphology to investigate their influences in conversion-based materials. Experimental results showed that spinel-phased MnO2 was formed during charge storage reactions for all samples, but the electrochemical performance varied based on the initial crystal structure. Among the polymorphs, lambda-MnO2 exhibited the highest reversible capacity of around 1270 mAh g(-1) due to its faster kinetics and structural similarity between cycled and pristine states. These findings suggest that polymorphs are an important factor in designing high-performance materials for next-generation rechargeable batteries.

Summary: Aqueous rechargeable batteries based on MnO2 are attracting attention due to their high theoretical capacity and redox potential, as well as their low cost and safety. However, the chemistry of MnO2 deposition/dissolution is not well understood, hampering its practical use in batteries. This study used an electrochemical quartz crystal microbalance technique to investigate the deposition/dissolution process and discovered that it involves pH-dependent Mn(iii)-intermediates. The presence of dissolved Mn3+ decreases the battery's performance, but the problem can be addressed by introducing redox mediators into the electrolyte.
