Front cover image: Relieving the stress or strain associated with volume change is highly desirable for high-performance SiOx anodes in terms of stable solid electrolyte interphase (SEI)-film growth. In article number 10.1002/cey2.141, Tao et al. demonstrate that the gradient regulation of Si-valence can eliminate the local stress and enhance the lithium-ion transport dynamics for SiOx anode, effectively boosting the cycle life and output power for batteries, and thus strongly driving electric vehicles.
