Lithium lanthanum zirconate (Li7La3Zr2O12, LLZO) is a highly promising solid electrolyte for lithium-ion batteries in that it possesses high conductivity (σ ~10‐4 S/cm) and chemical stability against elemental Li, potentially allowing pure Li anodes and greatly increasing energy capacity of the batteries. LLZO may have a cubic or tetragonal crystal...

Li-ion batteries allow us to store electrochemical energy efficiently and safely. Indeed, these batteries have revolutionized fields ranging from portable and wearable electronics to grid-scale energy supply. Typically, Li-ion batteries operate by polarizing and transferring lithium ions through organic solvents or gels. Unfortunately, these systems...

3D battery electrodes with solid-state electrolytes (SSE) are an attractive architecture for next-generation Li-ion energy storage due to their superior safety characteristics and potential for high power/energy densities. These electrodes are structured as arrays of plates or pillars with high aspect ratios (~100) onto which SSE must be conformally...
