Mutual Suppression of Mn3O4 and SiOx in an Innovative Anode Design for Enhanced Cycling Stability We designed the SiOx@C/Mn3O4 composite material with ultrafine particle size using a simple sol-gel method and calcination process. SiOx and Mn3O4 during the charge/discharge process can produce a mutual suppression effect to matigate volume expansion and maintain the long-term stability of two active materials.

Abstract:The aim of this paper is to extract the maximum power from wind energy for the doubly fed induction generator based wind turbine system (DFIG-WT) under the continuous stochastic perturbations of wind speed. The DFIG-WT is modeled as the Itô stochastic differential equations. The stochastic backstepping control method and the gain suppressing inequality technique are employed to guarantee that the relative rotor speed to the optimal value is bounded in probability.
