6 FAQs about [Battery nitrogen protection device]
Does the NXN nitrogen suppression agent prevent Li-ion batteries from spreading?
After performing hundreds of tests on li-ion batteries, we have found that the Siemens NXN nitrogen suppression agent effectively controls thermal runaway and stops it from spreading from module to module. In most cases, it even prevented cell-to-cell propagation.
What is the best solution to protect lithium-ion battery fire hazards?
Nitrogen suppression is the best solution to effectively protect lithium-ion battery fire hazards. By using high-pressure nitrogen cylinders (4351 PSI), the Sinorix NXN N2 solution has a smaller footprint, allowing for better utilization of space in smaller enclosures (e.g. a 20' BESS unit). licenses.
Is liquid nitrogen a good cooling solution for TR batteries?
Our previous study found liquid nitrogen (LN) exhibits excellent cooling performance for the TR batteries without damage to normal batteries, and can successfully suppress the TR of 100 % SOC batteries at 172.2 ℃, which is about 20 ℃ lower than the TR trigger temperature (Huang et al., 2021 ).
Are there any standards for detecting lithium-ion battery off-gas?
Currently there are no other global product performance standards for the detection of lithium-ion battery off-gas. Aspirating smoke detectors (ASD) continuously draw air samples from the areas requiring protection and evaluate them for the presence of particles of combustion (e.g. smoke, etc.).
Are nitrogen generators better than N2?
The fire protection concept of an ORS system is based on lowering the oxygen levels before the fire starts, then nitrogen generators are considered more convenient if compared with N2 purchase. According to the economic evaluation performed in this work the VAB useful life must exceed 2.5 years in order to be competitive with N2 purchase.
