Cadenza's Lithium Batteries Can Control Thermal Runaway -Lithium - Ion Battery Equipment
According to foreign media reports, Christina Lampe Onnerud, CEO of U.S. battery and energy storage developer CadenzaInnovation, recently announced that the "Supercell" lithium battery developed and produced by the company can prevent the spread of fire in the event of thermal runaway, which has been recognized by the industry certification body UL. , and its battery products have obtained the UL9540A certification of the combustion test.(Lithium - Ion Battery Equipment)
Obtaining this certification shows that the "Supercell" lithium battery can effectively handle thermal runaway and can prevent the transition from a service incident to a catastrophic event.
Cadenza, a company founded by Onnerud in 2012, has developed an innovative battery architecture and production platform that aims to eliminate important issues facing the energy storage industry today in a more cost-effective manner. As seen in dozens of battery energy storage system fires in South Korea and a fire and explosion at APS's energy storage system (ESS) in Arizona, the thermal runaway of the battery and the spread of the fire will cause Huge destruction.
Cadenza's Supercells are larger than the commonly used 18650 lithium battery cells
LampeOnnerud said in an interview with the industry media: "Our goal in designing battery products is that when one battery thermal runaway occurs, it will not cascade to other batteries. This does not mean that our batteries will never fail, but if there is a A failure is just a maintenance service event. The batteries we developed will not catch fire, they will not explode, and they will not set off an alarm for a sprinkler system or any kind of fire protection system."
Testing to UL1973 and UL9540A verifies that a battery in a thermal runaway condition will not burn and release dangerous levels of gases when it does so. Onnerud said the Cadenza-designed battery released so little gas that it was difficult to measure.
"While our battery products aren't as dramatic, putting these cells into thermal runaway is like nothing happened," he said.
Onnerud said Cadenza is licensing its battery production technology and platform to international customers, with some customer announcements expected soon, but the company seeks to manufacture batteries in the United States.
In 2018, the company received demonstration project funding from the New York State Energy Research and Development Authority (NYSERDA). The New York Power Authority (NYPA) has also actively supported its safety testing and reviewed Cadenza's testing data. Cadenza is also conducting research and development with an Australian battery start-up, EnergyRenaissa, which hopes to become Australia's first manufacturer of lithium-ion batteries for grid-scale energy storage.
As Onnerud points out, fires and explosions in lithium-ion storage systems can not only look bad in the media, thereby damaging confidence in the industry, they can also lead to the destruction of storage facilities and home construction. Four firefighters were seriously injured in April 2019 when a fire and explosion occurred at an energy storage facility deployed by APS at its McMicken substation in Arizona.
Onnerud said, "The fire and explosion caused the complete destruction of the containerized battery energy storage system. If the battery energy storage system is deployed in a high-rise building, if there is a fire and explosion, the consequences are unimaginable. The battery products we developed There will be no such event. If the battery fails, the maintainer will receive a notification on the phone that a battery has failed and needs to be repaired, but the battery will not catch fire and the user will only need to replace the one that appears A faulty battery will do, no bigger problems, and the battery storage system will still be up and running."
He said that the energy storage industry should not feel negative and pessimistic about the use of lithium batteries, but actively find ways to solve the problem. Some energy storage system suppliers, such as Powin Energy and Sungrow, have also obtained UL9540A certification, as have battery products from battery manufacturer Samsung SDI.
Onnerud suggested that the non-flammable batteries developed by Cadenza could be more cost-effective than using firefighting equipment and other methods to mitigate the thermal runaway problem of cascading battery packs.
"If the developer wraps all the batteries in fire blankets and adds deflagration vents to deal with a fire and explosion event, they will still face the pressure of spontaneous combustion," he said. "Our design ensures that the batteries go into thermal runaway when they go into thermal runaway."
