The phantom menace of dynamic soft-shorts in solid-state battery …
Short-circuiting is the worst-case scenario for lithium metal batteries. However, soft-shorts are small, highly variable, and transient short-circuits that can lead to misguided data interpretation and precede permanent battery failure. This work presents numerous characterizations of soft-shorts in solid-state batteries along with modeling of …

What is electrical short circuit & why is it dangerous?
Short Circuit Occurs: When a short circuit occurs, it creates a low-resistance path between two conductive elements in the circuit, often bypassing the intended load or component. This low-resistance path allows current to flow unchecked and at a significantly higher rate than what the circuit is designed to handle.
