Lithium-ion (li ion) batteries serve as the cornerstone power source for a wide array of rechargeable devices. Emerging in the 1990s, the evolution of li ion battery technology has been remarkable, spanning from powering cell phones and laptops to driving electric vehicles (EVs) and fueling utility-grade energy storage solutions.
What a role does the safety vent play in the safety of 18650-size
Generally speaking, there are several typical phenomena in the process of battery thermal runaway, including safety vent opening, gases releasing, ignition, ejection, combustion and so on (Ouyang et al., 2019a, Fu et al., 2015, Liu et al., 2016) which, the safety vent opening is usually followed by serious gases releasing and ignition; that is, safety vent opening warns
Venting for EV battery packs
If lithium-ion battery cells are damaged by puncturing, overcharging, manufacturing defect or other causes, they can release gas and heat. This can trigger other cells to decompose, leading to a thermal runaway condition, where rapidly increasing temperatures and pressures released by cells exceed the venting capability of the ePTFE membrane vent.

6 FAQs about [Lithium-ion battery ventilation requirements]
What are the requirements for a stationary battery ventilation system?
Ventilation systems for stationary batteries must address human health and safety, fire safety, equipment reliability and safety, as well as human comfort. The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration.
Should stationary battery installations be ventilated?
Ventilation of stationary battery installations is critical to improving battery life while reducing the hazards associated with hydrogen production (hydrogen production is not a concern with Li-ion under normal operating conditions [it is under thermal runaway conditions]).
What are the requirements for a lead-acid battery ventilation system?
The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration. Flooded lead-acid batteries must be provided with a dedicated ventilation system that exhausts outdoors and prevents circulation of air in other parts of the building.
How much air should a battery room be ventilated?
The battery rooms must be adequately ventilated to keep the concentration of hydrogen gas within safe limits. Some codes suggest that the battery rooms shall be ventilated at a minimum rate of 1.5 cubic feet per minute per square foot, with care to ensure proper air distribution to and within the battery storage area.
Do lead-acid batteries need ventilation?
For lead-acid batteries, adequate ventilation is crucial to prevent the build-up of hydrogen and oxygen gases, which are byproducts of the battery’s operation. Without decent ventilation, these gases can result in an increase in pressure within the battery, posing a safety risk.
Does a battery room need a ventilation system?
The ventilation system for the battery room shall be separate from ventilation systems for other spaces. Air recirculation in the battery room is prohibited. Exhaust air through a dedicated exhaust duct system if the battery room is not located on an outside wall.
