10,000 LG CHEM LITHIUM BATTERIES RECALLED OVER FIRE HAZARD 2021-08-24 00:00:00
August 19,2021: Around 10,000 residential storage system lithium batteries by LG Chem subsidiary LG Energy Solutions have been recalled because of a fire hazard, the US Consumer Product Safety Commission announced on August 4. The RESU 10 (Type-R) batteries were recalled after warnings were issued that they ‘can overheat, posing a risk of fire and emission of harmful smoke’. Five reports were received of the wall-mounted batteries, which store energy generated by solar panels, causing property damage and one injury, the CPSC said. The batteries were made in LG Chem’s factory in Nanjing, China, between 2017 and 2018, according to Korean media, which said the recall had caused the firm’s stock price to drop by 6.7%. In December 2020, around 1,815 units of the same model were recalled for the same reason, the CPSC having received five reports of fires resulting in minor property damage, but no injuries. The latest recall came just two days after a four-day lithium battery fire was put out at a utility-scale Tesla battery site in the Australian state of Victoria. International media reported that a 13-tonne lithium battery caught fire inside a shipping container and could easily have spread to other battery containers, but was kept under control and then finally put out. The ‘Victoria Big Battery’ was installed by French energy firm Neoen in 2017, when it was the largest grid-connected energy storage system in the world at 100MW/129MWh. Tesla owner Elon Musk famously offered to waive the installation fee if it could not be completed within 100 days—and it was. It was doubled in size in September 2020. Lithium battery fires are notoriously difficult to extinguish safely because they react with water, even when they are not alight. “Statistically it’s not if they fail, but when,” says George Brilmyer, CTO at HighWater Innovations and formerly R&D manager of separator firm Microporous. “It’s a million to one chance that a cell will fail but if you have tens of thousands of them on a cargo of containers, the statistics are against you that one is going to fail. With thermal runaway it’s then a cascading process as one by one ignites, and that’s why it takes days to put them out.” The batteries have to be soaked in water for long enough to make sure that the water gets right into the cells, otherwise they can reignite. Brilmyer believes the economic case for deploying lithium in containers is flawed. You are not moving them around, they are staying in a container on the ground, there’s no reason why you should be using lead at a fifth of the cost. “Parts of Australia are very warm, so lithium cells will probably need air conditioning on to keep them cool—well if you do the energy balance and take that into account it doesn’t add up.”

GM Recalling 73,000 Bolt EVs with LG battery at cost of $1 billion, Halts sales 2021-08-23 00:00:00
WASHINGTON, Aug 20(Reuters)-General Motors Co GM.N said on Friday it will recall about 73,000 Chevrolet Bolt electric vehicles at a cost of$1 billion to address fire risks and indefinitely halt sales over the battery issue. The massive recall comes as GM is aggressively moving to ramp up electric vehicle sales. GM said it will seek reimbursement from its battery supplier, LG. The largest U.S. automaker said the recall covers all remaining Bolt vehicles not previously recalled in July.GM said it will replace defective battery modules in Chevrolet Bolt EVs and EUVs with new modules. It added it was pursuing commitments from LG for reimbursement of the recall. GM said earlier that previous Bolt recalls would cost about$800 million. The $1 billion is in addition to that, a spokesman said. In July, GM issued a new recall for nearly 69,000 Chevrolet Bolts for fire risks after reports of two fires and said it will replace defective battery modules as needed. GM said it will not sell Bolt vehicles until it is satisfied with the fix. It added it is "working aggressively with LG to increase production as soon as possible.GM will notify customers when replacement parts are ready." Some Bolt EVs recalled in July were first recalled in November for fire risks and at least one of the two new fires was in a vehicle that had already had the software update released as part of that recall. The July recall came after GM and the National Highway Traffic Safety Administration (NHTSA) urged Bolt owners to park their vehicles outside and away from homes after charging. GM in July had confirmed a total of nine Bolt fires. The automaker said in rare circumstances, the batteries supplied to GM for these vehicles may have two manufacturing defects–a torn anode tab and folded separator–present in the same battery cell, which increases the risk of fire. LG officials could not immediately be reached for comment. After investigation into the manufacturing processes at LG and disassembling battery packs, GM said it "discovered manufacturing defects in certain battery cells produced at LG manufacturing facilities beyond the Ochang, Korea, plant. GM and LG are working to rectify the cause of these defects." The new recall includes 9,335 Bolt EVs from model year 2019 that were not included in the previous recall and 63,683 2020–2022 model year Chevrolet Bolt EVs and EUVs. GM said owners of the vehicles in the new recall should park them outside immediately after charging and not leave them charging indoors overnight. https://www.nasdaq.com/articles/gm-recalling-73000-bolt-evs-at-cost-of-%241-billion-halts-sales-2021-08-20
