Mechanochemical halide segregation therefore matters for more than the particular performance numbers reported by G.-L. Xu et al. It shows that electrode manufacturing can be treated as a chemical design variable. The next advance will depend on converting this striking empirical observation into a quantitative process-structure-property relationship and demonstrating that its interfacial advantages survive under the low pressure, thin electrolyte and practical anode conditions demanded by real solid-state battaries.
