The industrialization of all-solid-state batteries faces three major hurdles: interface challenges, the risk of dendrite formation, and high manufacturing costs.

The industrialization of all-solid-state batteries faces three major hurdles: interface challenges, the risk of dendrite formation, and high manufacturing costs.

Poor mechanical stability at the interface Solid–solid contact is prone to microcracking under volume changes during charging and discharging (10%–20%), leading to increased interfacial resistance and a sharp decline in cycle life. Isostatic pressing or buffer layers are required, but these approaches raise costs. Insufficient electrochemical stability at the interface Sulfides and oxides undergo side reactions with high-voltage cathodes and lithium-metal anodes, forming high‑resistance interphases that severely limit rate capability (currently making it difficult to achieve rates above 2C). Nano‑coating is necessary, adding 15%–20% to the cost. Lithium dendrite suppression remains challenging All-solid-state batteries do not completely eliminate lithium dendrites; lithium can still penetrate defects or cracks within the electrolyte, causing short circuits and posing safety risks. Interface engineering—such as incorporating lithium‑affinitive layers—is required, which increases process complexity.
