Silicon (Si) anodes suffer from severe volume expansion and unstable solid electrolyte interphase (SEI), limiting their practical application in lithium-ion batteries. Here, we present Si–MoS2 composite anodes that are constructed via liquid-phase exfoliation of MoS2 followed by spray-drying integration with Si. Bath ultrasonication produces thin-flake MoS2 with reduced stacking coherence and expanded interlayer spacing (~0.625 nm), enabling a more uniform composite structure

Lithium metal is a promising material for high-energy-density batteries, yet its electrochemical behavior is strongly influenced by the poorly controlled initial surface state of commercial lithium foils. Variations arising from manufacturing, storage, and handling introduce interfacial heterogeneity, leading to performance scatter and limited reproducibility across studies. Herein, we establish a modular standard operating procedure (SOP) to systematically regulate lithium m

Primary lithium (Li) metal batteries are widely used but are typically discarded after single-use operation, resulting in a dispersed and underutilized Li-containing waste stream. Here, we report an integrated electrochemical–chemical pathway for Li recovery from spent primary Li metal batteries. Residual Li is first reactivated through controlled electrochemical rejuvenation, inducing Li redeposition onto the anode-side casing. The regenerated Li is then selectively extracte

Congratulations, ICST Class of 2026! 🎓 It feels like just yesterday that this journey began, and now it's time to celebrate how far you've come. Along the way, you've learned, grown, overcome challenges, made memories, and built friendships that will stay with you long after graduation. As you take your next steps, remember that it's okay not to have everything figured out. Stay curious, keep learning, be open to new opportunities, and trust yourself. The future may be uncer

I am pleased to share that my NSTC Ta-You Wu Memorial Award profile page is now available online.
