Getting to Know the ''Ghost'' Inside Batteries | MOTOR
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.
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 been studied widely, a

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
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
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
Insights into soft short circuit-based degradation of lithium metal
Here, soft short circuits formed during prolonged unidirectional Li plating were detected with coupled EIS and NMR, where three stages of Li plating: nucleation, surface area growth and soft shorts formation
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.
