More and more attention has been paid to lithium–sulfur (Li─S) batteries due to their high energy density and low cost. However, the intractable “shuttle effect” and the low conductivity of S and its reaction product, Li2S, compromise battery performance. To address the inherent challenges, a hollow composite catalyst as a separator coating material is designed, in which CoFe alloy is embedded in...
The modeling of high‐order converter systems and design of their closed‐loop controllers are difficult due to their high nonlinearity, hence high‐order systems, large number of zero‐poles, and complex frequency‐domain characteristics. To ease the design methodologies, this paper studies high‐order power converters and proposes a modeling and control method for such converter systems with order reduction...
