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: Li2MnO3, as a traditional member of lithium-rich layered cathodes, shows large specific capacity, but suffers from capacity fading and voltage decay. Iridium doping improves electrochemical performance, with dopant concentration and calcination temperature affecting the performance due to intrinsic microstructure and crystallization. The mechanism of improvement lies in the structure stability induced by iridium doping in TM sites, enhancing high-capacity cathode materials for lithium-ion batteries.

Summary: A lithium-potassium coinsertion vanadate nanoflake was synthesized and exhibited excellent zinc-ion storage ability, impressive rate performance, and long cycling stability as the cathode material for aqueous zinc-ion batteries. The high electrochemical performance is attributed to the kinetically favorable rich oxygen vacancies and nanoflake structure induced by lithium ions, as well as the pillar effect of lithium ions ensuring the stability of the V-O layer structure. This study broadens the synthesis path of layered vanadium oxides and promotes their application as cathode materials for zinc-ion batteries.

Summary: Niobium pentoxide (Nb2O5) is used as a negative electrode material for energy storage devices, but its poor electronic conductivity limits its performance. This study used argon-ion bombardment to enhance the interfacial properties of Nb2O5 by introducing conductive NbOx species on the electrode surface. The introduction of a NbOx layer improved the electrochemical performance, increasing the reversible capacity from 138 mAh g-1 to 211 mAh g-1. This method provides a way to enhance conductivity and surface modification simultaneously, improving the electrochemical performance of Nb2O5.
