Cubic Gas Sensing Solutions in Lithium-Ion Batteries Thermal Runaway Application
Recent years, lithium-ion batteries thermal runaway events have attracted widespread attention. To further reduce the loss of life and property caused by lithium-ion batteries thermal runaway, some important regulations have been promulgated. UN GTR 20: “The vehicle shall provide an advance warning indication to allow egress or 5 minutes prior to the presence of a hazardous situation inside ...

What is Thermal Runaway in Lithium-Ion Batteries?
Thermal runaway is a violent chain reaction of exothermic chemical reactions resulting in an uncontrollable increase in system temperature. Now, where does this reaction might unfold? Batteries and energy storage systems, which are integral parts of tech around us, are the main stage for this drama. They sometimes fall victim to thermal runaway, turning a peaceful power source into a potential ...

Major EV Battery Safety Recalls? Electra`s AI Technology Can Help
Electric vehicle recalls have accelerated as the risk of battery thermal runaway due to faults and failures remains a major pain point in the eMobility industry. General Motors recently took a $1.8 billion hit for battery warranty and replacement costs for the Chevrolet Bolt, according to CNBC, and it is not the only major OEM challenged by battery malfunction. While thermal runaway in electric ...

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

Heat Flux Sensing in Battery Monitoring
Batteries are critical devices for many people today: they power smartphones, laptops, and even cars! The wide adoption of batteries was possible because of the invention of the lithium-ion battery (whose inventors won the Nobel Prize this year). If we look at its results, the Li-Ion battery was surely one of the most important engineering achievements of the last 50 years. Given its importance, ...

Fiber Optic Testing Helps Ensure EV Battery Health and Safety
EVs face unique design challenges in order to be competitive with gasoline-powered vehicles. The root of many of these challenges is in the EV battery pack. Drivers want similar vehicle range per charge when compared to a tank of gas, as well as the convenience they are used to with refilling a tank in just a few minutes. This means battery packs need to be able to store enough energy to go ...

Ways to Properly Charge Stationary Lead-Acid Batteries
After hundreds of site visits, multiple battery systems tests, and the examination of numerous maintenance records, I would say that almost 50 percent of all stationary lead-acid batteries are not being properly charged. Constant-Current Charging: Not generally used for stationary batteries except during the manufacturing process. Constant-Potential / Constant Voltage Charging: Used in ...

Battery Failure Prevention with Proper Mitigating Actions
Lithium ion battery failure follows four primary stages, which are initial abuse, off-gas generation, smoke generation, and fire propagation. Both the initial abuse and off-gas generation stages fall within what’s called the “preventative region”. In that region, specifically during the off-gas stage, implementing proper mitigating actions can help prevent battery failure. As ...

Reducing fire and explosion risk of lithium-ion batteries
On the 7th January 2013 cleaning staff onboard a Boeing 787 aircraft noticed smoke in the rear cabin. Closer inspection by a mechanic discovered a fire originating from the lid of the APU battery case. Fortunately, the plane was parked at Logan International Airport, USA, at the time, so none of the 183 passengers and 11 crew were hurt. Nine days later, on 16th January 2013, a Boeing 787 had to ...

2019 Nobel Prize in Chemistry goes to the fathers of the fossil-free era
This years’ Nobel Prizes have just been awarded and the chemistry prize recognizes the three men who developed the lithium-ion battery. It’s a technology that’s taken for granted by many of us, but this rechargeable, powerful, compact and lightweight battery has made the technology we take for granted possible. It’s why mobile phones are so lightweight and why you can use ...

If Cobalt is So Bad, Why are Some Companies Still Using it in Batteries? Part 1
The terrible consequences of cobalt mining and usage are both well documented and heartbreaking. Devastating environmental impacts from extration that render large swath of land unusuable and polluted waterways. Children forced to work in dangerous and claustrophobic 'artisanal' mines (a truly sinister euphemism). Toxicity, lung disease, heart failure, and cancer from exposure, even ...
