Conclusions This study proposes a novel TR mitigation approach for high-energy batteries using chemical poison. The self-destruction battery with the poison layer is designed, and its effectiveness in mitigating thermal runaway hazards is verified at the material, electrode, and cell levels.
A poison agent scheme is proposed to mitigate the thermal runaway hazards of high-energy lithium-ion batteries, and the poisoning mechanism and pathway are experimentally investigated to verify the effectiveness of the proposed scheme. 1. Introduction
A stranded ESS battery, which is commonly found after an ESS fire has been extinguished and the battery terminals have been damaged, poses a shock hazard to those working with the damaged ESS. It still contains an unknown amount of electrical energy, and this stranded energy can also lead to reignition of a fire within minutes, hours, or even days after the initial event.
Abusing a battery can result in an inoperable Energy Storage System (ESS). It can also lead to overheating, fire, and explosion. Mechanical abuse occurs when the battery is physically compromised, such as when it is crushed, dropped, penetrated, or otherwise distorted to failure by mechanical force.
This study describes a new route to mitigate the battery thermal runaway (TR) hazard by poison agents. First, the self-destructive cell is built using the embedded poison layer. Then, the poisoning mechanism and paths are experimentally investigated at the material, electrode, and cell levels. Finally, the proposed route is verified by TR tests.
During the thermal runaway experiment, the battery had a violent combustion reaction, and the current collector had combusted after the battery explosion. LCO with 50% and 100% SOC were similar in the products of highly toxic and toxic emissions.
