The gas release behavior varies with the three cathode materials. The relationship between heat production and gas release of batteries is further analyzed. The process of thermal runaway (TR) of lithium-ion batteries (LIBs) is often accompanied by a large amount of heat generation and gas release.
The released gases were analyzed with aid of OEMS (on-line electrochemical mass spectrometry). The experimental studies showed that at cycling of lithium-ion batteries on their cathodes, the gases CO 2 and CO are released, while on their anodes the gases C 2 H 4, CO and H 2 do.
LIBs shows gas release behavior and heat generation during the TR process, which stimulates the strong oxidation reaction inside the battery and releases a large amount of gas in a very short period. This causes an impact force . The impact force is the impact energy of the battery released from the kinetic energy.
In summary, the researchers have investigated the storage and release of hydrogen in LiCoO 2 cathode materials for lithium-ion batteries.
The relationship between heat production and gas release of batteries is further analyzed. The process of thermal runaway (TR) of lithium-ion batteries (LIBs) is often accompanied by a large amount of heat generation and gas release. However, the gas release behavior during the process of TR remains unclear.
Subsequently, the gas releases behavior of fully charged batteries during the TR process is obtained. Before the battery temperature approaches the uncontrollable temperature, the electrolyte volatilization and gas releasing are decoupled, the gas release of LFP, LMO and NCM batteries are 0.094 mol, 0.042 mol and 0.058 mol, respectively.

Battery Safety: What is Off-Gassing and Why Does it Occur
Off-gassing refers to the release of gases from lithium-ion batteries often as a result of abuse or misuse. When a battery is subjected to conditions such as overcharging, over-discharging, or physical damage, it can lead to the breakdown of internal components, causing the release of gases. These gases typically include carbon dioxide, carbon ...
