Dendrite reduction in Solid-State batteries through lamination

Applications: Solid state lithium batteries

Over many recharging cycles of solid-state lithium batteries, lithium is not re-plated onto the anode uniformly and Li dendrites grow – this work addresses this problem to extend the lifetime of batteries and prevent short circuits.

Features	Benefits
Laminated electrolyte construction	Creates locked-in stresses in the electrolyte for increased strength. This is a simple and well-known manufacturing process that can be implemented quickly and relatively cheaply.
Reduced dendrite formation	Dendrites are highly detrimental to the performance of solid-state lithium batteries – they are associated with the development of cracks in the solid electrolyte, leading to decreased efficiency in the cell and possible short circuits. By reducing dendrite formation and growth we can extend the lifetime and performance of these batteries.
Residual compressive stresses	The compressive stresses in the electrolyte make it significantly harder for a dendrite to penetrate the surface and cause damage. The lithium is forced to plate out onto the surface of the electrolyte where it can be effectively used in the subsequent discharge cycle. The surface compressive stresses also increase the strength of the electrolyte.
