Mitigating Thermal Runaway of Lithium-Ion Batteries
A new concept, which we refer to as the "self-poisoned" technique, might be helpful in reducing the total energy release or diminishing the heat release rate. 20 Current literature has some good works on the cell design with the "self-poisoned" function, including (1) the use of thermo-responsive materials to block the contact between ...
Analysis of gas release during the process of thermal runaway of lithium-ion batteries …
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. Three types of 26700 LIBs with LiFePO 4 (LFP), LiMn 2 O 4 (LMO) and LiNi 0.5 Co 0.2 Mn 0.3 O 2 (NCM) as cathodes …

Venting for EV battery packs
For example, dimensions of the vent need to be accounted for in the battery pack and vehicle design. While dual-stage vents can be manufactured with a diameter less than 2 in. (50 mm) and a height of approximately 0.4 in. (10 mm), space is often limited in areas of battery packs.
