Despite their promise, transitioning solid-state batteries from the laboratory to mass production presents significant hurdles. One major challenge is the creation of intimate contact between the solid electrolyte and the electrodes. Imperfect contact can increase internal resistance, reducing performance and efficiency. Another issue is the fragility of some solid electrolytes, which can crack during battery operation due to volume changes associated with charging and discharging. Finally, current manufacturing processes are often expensive and slow, hindering widespread adoption. New techniques, such as thin-film deposition and 3D printing, are being explored to overcome these challenges and improve scalability. The sector is heavily dependent on achieving consistent quality control to mitigate potential failures.
