The process involves mechanically kneading lithium foil and LLZO particles. The LLZO particles are placed on top of the lithium foil, which is then folded in half and pressed flat using a roll press. This folding and pressing cycle is repeated multiple times (the research team repeated it 30 times) to create a composite material in which the lithium and LLZO particles are evenly mixed.

Optical microscope images showing the growth of lithium as it accumulates on the surface of the control lithium anode and the developed composite anode. (Top) On the conventional lithium anode, lithium dendrites are formed, rapidly increasing in size. (Bottom) On the developed composite material, lithium is deposited much more densely and stably.

The graph shows the performance of lithium-metal batteries using a control lithium foil and the developed composite material as anodes. As the number of charge-discharge cycles increases, the developed composite material exhibits significantly better capacity retention compared to the lithium foil.
