Monitoring Off-Gases to Guard Against Thermal Runaway Risk with Li-Ion Batteries

  • By : PureAire Monitoring Systems
  • Posted on : April 01, 2022

Lithium-Ion Batteries Rechargeable lithium-ion (“li-ion”) batteries (comprised of cells in which lithium ions move from a negative electrode through an electrolyte to a positive electrode during discharge—and the other way around when charging) were first described conceptually in the 1970s. Following initial prototype development in the 1980s, li-ion batteries became commercially viable in subsequent decades, […]

  • Posted on : November 09, 2021

What is Oxygen Deficiency? The air we breathe is made up of 78% nitrogen, 21% oxygen, and trace amounts of other gases such as carbon dioxide, neon, and hydrogen. The Occupational Safety and Health Administration (OSHA) defines an environment in which oxygen levels fall below 19.5% as an oxygen-deficient atmosphere, which should be treated as […]

Carbon Dioxide Safety – Why It’s Important to Monitor Carbon Dioxide

  • By : PureAire Monitoring Systems
  • Posted on : August 19, 2021

What is Carbon Dioxide? Carbon dioxide is the fourth most abundant gas in the earth’s atmosphere after nitrogen, oxygen, and argon. At room temperature, carbon dioxide (CO2) is a colorless, odorless, non-flammable gas, but at different temperatures and pressures, carbon dioxide can be a liquid or a solid (i.e., dry ice). Carbon dioxide is produced […]

When Freshness Counts – Modified Atmosphere Packaging

  • By : PureAire Monitoring Systems
  • Posted on : March 12, 2021

Centuries ago, merchants and shippers would place a lit candle inside barrels used to store biscuits before closing the lid. The idea was that the candle flame would deplete the oxygen inside the barrel to help keep the biscuits from spoiling. These days, the candle flame has been replaced by processes called Modified Atmosphere Packaging […]
