No need to be ignorant as to what it means, this sums up the issues with solid state very simply for you..

Solid-State Manufacturing Challenges

Solid-state battery manufacturing presents a complex set of challenges beyond the typical issues encountered in traditional lithium-ion battery production. One of the most pressing concerns is the scalability of the technology.

Solid-state batteries have shown promise in laboratory settings, but translating these small-scale successes into mass-produced, commercially viable products is a formidable task.

The materials used in solid-state batteries, such as solid electrolytes, are often more expensive and less readily available than their liquid counterparts, adding to the cost and complexity of scaling up production.

Solid-state batteries require a solid electrolyte compatible with the anode and the cathode materials. Any mismatch can lead to mechanical stresses, causing the layers to separate or crack, compromising the integrity and safety of the battery. This necessitates rigorous quality control measures and advanced manufacturing techniques to ensure all components are perfectly aligned and integrated.

Finally, unlike lithium-ion batteries, solid-state batteries don’t benefit from a vast economy of scale. Where the existing manufacturing infrastructure is largely tailored for liquid electrolyte-based lithium-ion batteries, transitioning to solid-state technology means either retrofitting these facilities, which is costly and time-consuming, or building new manufacturing lines from scratch.
