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
Detection Method for Soft Internal Short Circuit in Lithium-Ion Battery
In this paper, estimating the resistance with the whole terminal voltages and the load currents of the pack, a detection method for the soft internal short circuit in the pack is proposed.
Insights into soft short circuit-based degradation of lithium metal
The uneven electrodeposition of Li results in dendrite formation and potentially hazardous situations such as cell short-circuiting and thermal runaway. Although lithium plating has
Diagnosis of Soft External Short Circuit Faults for Lithium-Ion Battery
Abstract: When soft external short circuit (ESC) occurs on a lithium-ion battery module, all cells in the module exhibit fault characteristics similar to those of an internal short circuit (ISC), thereby posing a
Getting to know the
An Argonne team developing materials for solid-state batteries took an unexpected detour to investigate tiny short-circuits known as soft-shorts. Their insights will benefit battery researchers
Getting to Know the ''Ghost'' Inside Batteries
The team determined that the batteries were experiencing soft-shorts, which are tiny, temporary short-circuits. With a soft-short, lithium filaments grow from the anode to the cathode.
The phantom menace of dynamic soft-shorts in solid-state battery
Here, we present a comprehensive outline of the detection and analysis of soft-shorts in solid-state lithium metal cells with composite polymer electrolytes as well as a fundamental
Ghosts in the Machine: Scientists Identify Battery
An Argonne team developing materials for solid-state batteries took an unexpected detour to investigate tiny short-circuits known as soft-shorts. Their insights will benefit battery
Toward Deciphering the Internal Menace of Battery Safety: Soft Short
Abstract Internal short circuits (ISC) from Li dendrites pose crucial challenges to the safety and reliability of electric vehicle power batteries. However, fundamental knowledge of how
