PNNL develops system to prevent lithium-ion ESS fires before they start

Tue, 05/25/2021 - 10:54 -- paul Crompton

A team from the U.S. Department of Energy’s Pacific Northwest National Laboratory has developed a sensor system that can prevent dangerous conditions developing in outdoor lithium-ion battery cabinets. 

Supported by DOE’s Office of Electricity, IntelliVent automatically opens cabinet doors to prevent buildup of flammable gases if it detects smoke, heat, or gas.

The system can be retrofitted into cabinet-style battery enclosures, such as those used in stationary grid energy storage applications. 

Due to limitations of the product standard, the system is not designed to NFPA-69 (Standard on Explosion Prevention Systems). 

Intellivent, which is available for nonexclusive licensing, was designed to work with a variety of sensors.

A 15-month investigation in the US found that dendritic growth had caused cascading thermal runaway, which in turn caused an explosion at a lithium-ion battery storage facility operated by the Arizona Public Service (APS) utility.

The explosion in Surprise, Arizona, on 19 April, 2019, seriously injured four fire fighters. 

Contributing factors into the explosion included no ventilation for flammable ‘off-gasses’.

Bobby Ruiz, the fire chief in Peoria, Arizona, whose firefighters were injured in the explosion, said: "This is absolutely in the right direction. Getting all doors open early before gas buildup will make the incident safer. 

“It will also increase situational awareness by being able to see if the batteries are smoking or are on fire. And, if extinguishment is needed, we can direct the water right at the modules from a safe distance." 

The Snohomish County Public Utility District’s new Arlington Microgrid and Clean Energy Center, in Everett, Washington, will be the first to install the safety technology when it retrofits a 1.2 MW battery with the IntelliVent system.

LIBs inch ahead in battery market, but Pb has power to grow

Lithium-ion batteries have grabbed a larger slice of the worldwide battery market than lead for the first time, but Pb will continue to grow at a “modest rate”, according to a top industry analyst.

Battery expert Dr Geoffrey May (pictured) told the International Lead Association’s PB2019 conference in Madrid that lithium-ion had a worldwide market share of US$40 billion in 2018, compared to $37.5bn for lead. This was the first time lithium-ion batteries had been ahead, he said.

Audi battery fire risk prompts E-Tron recall in US

German car manufacturer Audi is recalling its first all-electric vehicle rolled out in the US— the ‘E-Tron’— due to the risk of battery fires.

A spokesperson for the company, which is owned by Volkswagen, told BEST Battery Briefing “moisture could, in very rare cases, enter the high-voltage battery through the low-voltage wiring via the charging-socket grommet, due to production tolerances in the manufacturing of wiring harnesses”.

Li-powered hoverboards top fire risk concerns in US

Consumer safety chiefs in the US have issued a fresh warning about fire risks from a range of lithium-ion powered devices and toys— with hoverboards at the top of the list of concerns.

Hoverboard importers, retailers and distributors in the US have been urged to review product safety standards after US Consumer Product Safety Commission (CPSC) data showed the toys— also known as self-balancing electric scooters— were responsible for more than 280 fires in the country since 2015 and three deaths.
