Owing to these advantages, the optimal LiCr 0.01 Al 0.05 Mn 1.94 O 4 delivers a good electrochemical performance with a high first discharge capacity of 118.5 mA h g −1 and a capacity retention of 70.8% after 1000 cycles at 1 C. Even at relatively high current rates of 15 and 20 C, a durable and prolonged cycling performance of up to 3000 ...

In this Perspective, a Pd/Cu-cooperative catalytic system for alkene arylboration is highlighted that allows for the controlled introduction of substituents. In particular, examples that allowed for divergent reactivity from a single substrate based on the tuning of catalysts and reaction conditions are emphasized.

Li 2 S, a fully lithiated state of sulfur cathode with high capacity, is promising for lithium sulfur battery or lithium ion battery. To further decrease the cost and improve the utilization, single atomic Co catalyst is synthesized and embedded in inexpensive converted-Li 2 S nanocomposite. Theoretical simulations and electrochemical measurements demonstrate that the kinetics of …
