Heterogeneous current collector in lithium-ion battery for thermal-runaway mitigation

Current collector accounts for more than 90% of the electric conductivity and 90% of the mechanical strength of the electrode in lithium-ion battery (LIB). Usually, current collectors are smooth metallic thin films. In the current study, we show that if the current collector is heterogeneous, the heat generation becomes negligible when the LIB cell is subjected to mechanical abuse. The phenomen...

Role of Amines in Thermal-Runaway-Mitigating Lithium-Ion Battery.

Benzylamine (BA), dibenzylamine (DBA), and trihexylamine (THA) are investigated as thermal-runaway retardants (TRR) for lithium-ion batteries (LIBs). In a LIB, TRR is packaged separately and released when internal shorting happens, so as to suppress exothermic reactions and slow down temperature increase. THA is identified as the most efficient TRR. Upon nail penetration, 4 wt % THA can reduce ...
