(Bloomberg) — A major fire at a data center in South Korea that destroyed a wide range of key digital services for days — snarling banking, ride-sharing and online deliveries — is reigniting security concerns in a nation that is a key global supplier of lithium. . -ion cells used in electric vehicles.
The day-long outage followed an Oct. 15 fire at a data center in Pangyo that engulfed batteries used in backup power systems, affecting key local technology companies including Kakao Corp., South Korea’s near-ubiquitous social media giant and provider the country’s most popular instant messaging service.
Kakao users were left unable to find a taxi, pay for groceries or chat with family members, a disruption that prompted the company’s co-chief executive to resign and led lawmakers to question the risks of concentrating too much digital power in one entity.
Even with SK C&C, the operator of the data centre, still investigating the cause of the fire, the incident has sparked a fresh round of battery safety concerns. That is important for the electric car sector, given that three South Korean companies – LG Energy Solution Ltd., SK On Co. and Samsung SDI Co. – among the top tier of global battery suppliers.
“Safety concerns are re-emerging over lithium-ion batteries, and the government needs to step in to prevent similar accidents from happening because once things go wrong with batteries, the impact is often unbearably significant,” said Lee Hoguen, automotive professor. engineering at Daeduk University.
The latest fire could be a specific negative for SK On, a supplier to Ford Motor Co. and Volkswagen AG, which provided batteries in the data center with the intention of providing backup power and preventing outages, according to Yoon Joonwon, a fund manager at DS Asset Management, which invests in the technology sector. SK On said it received no alerts on its battery management system — which would indicate any problems, including changes in voltage or current — until the fire started at 3:19 p.m. local time.
South Korea has been heavily involved in the debate over the safety of batteries used in vehicles and massive power storage centers. Last year, manufacturers LG Energy Solution and LG Electronics Inc. more than $900 million in payments from the General Motors Co. recall. of Chevrolet Bolt electric vehicles.
A spate of fires at energy storage sites between 2017 and 2019 prompted intervention by the country’s government and manufacturers to boost standards, and is cited as one of the key factors that has hampered South Korea’s efforts to boost the share of clean energy in its power grid.
Lithium-ion batteries sparked 60 fires across the five boroughs between January.

In addition, fires at landfills or battery recycling facilities have been attributed to improper disposal of lithium-ion batteries.
Why are lithium battery fires hard to put out?
Traditional methods of stopping the fire, such as extinguishing it in water, are often insufficient to extinguish the flames because the battery packs are difficult to reach and retain enough heat to re-ignite over and over again as soon as the water stops flowing.
How do firefighters put out a lithium battery fire? Class D fire extinguishers are effective against lithium-metal battery fires. Lithium-ion battery fires are Class B fires, which indicate the presence of flammable liquids, so they can be extinguished with a standard dry chemical or ABC extinguisher.

Can a lithium fire be put out with water?
The US authorities have conducted a lot of research on how to turn off lithium-ion batteries. In 2013, the Fire Protection Research Institute sponsored by the US Department of Energy found that water can be used to extinguish a burning lithium-ion battery.
Why is it so hard to put out lithium fires?
As firefighters have discovered in recent years, lithium-ion battery fires are prone to re-ignition. That’s because the lithium salts in the battery are self-oxidizing, which means they can’t be “starved out” like a traditional fire.
What is the biggest cause of lithium-ion batteries exploding?
Apart from that, in intense thermal events, the flammable electrolyte, together with various flammable / toxic gases such as hydrogen (H2), methane (CH4), carbon monoxide (CO) and hydrofluoric acid (HF), can escape from the Li- ion battery. The release of these flammable gases causes fires and explosions.
How do I keep my lithium-ion battery from exploding? Avoid charging your device around flammable materials, such as a bed, sofa or on paper. Charge the power cord that came with your device. Never store li-ion batteries near heat sources or in high temperatures, such as direct sunlight, radiators or laptops.
How do lithium-ion batteries start fires?
Most fires that occur from lithium batteries are the result of thermal runaway. Thermal runaway occurs when conditions are met that cause reactions to occur and cannot be easily stopped. These reactions are exothermic, which means they release heat, and that heat may be enough to cause a fire.
How do you stop a lithium battery fire?
Traditional fire extinguishers, such as foam and water, do not work on lithium battery fires. The only way to extinguish a lithium battery fire is to flood the battery with water. A Lithium Fire Blanket will safely isolate a lithium fire battery for hours, until it can be flooded and extinguished.

What is the largest problem with lithium-ion batteries?
However, lithium-ion batteries are extremely sensitive to high temperatures and are inherently flammable. These battery packs tend to degrade much faster than they normally would, due to heat. If a lithium-ion battery pack fails, it will burst into flames and can cause widespread damage.
Is there a problem with lithium batteries?
Alongside recycling, the production of lithium batteries is also dangerous. Mining the various metals needed to make a lithium battery requires vast resources – it takes 500,000 gallons of water to mine one ton of lithium. Mining for the metals in lithium batteries is also known to be toxic to human health.
What causes a lithium battery to explode?
But producing all that electricity also creates heat, which can lead to battery fires and even explosions. This is especially true when a battery is damaged or defective, and uncontrolled chemical reactions (also known as thermal runaway) are allowed to occur.
Is it common for lithium batteries to explode?
Fortunately, large explosions caused by Li-ion batteries are a rare occurrence. However, if they are exposed to the wrong conditions, there is a small chance that they will catch fire or explode.
