Columbus, OH – Aug. 24, 2020 – Li-ion Tamer Group (https://li-iontamer.com), a developer of a gas detection system designed specifically for lithium-ion batteries, created by Nexceris, introduced plans today for its latest monitoring system. The third generation Li-ion Tamer product will continue to help monitor off-gas events and help prevent thermal runaway occurrences, but also will provide users access to temperature, humidity, air quality and raw gas data.

The Li-ion Tamer Group (LTG) has 10 years of experience studying how lithium-ion batteries fail, and developing products to increase the safety of energy storage systems. Continued support from the Department of Defense, Department of Energy and DNV-GL has created exposure to hundreds of failures of lithium-ion battery cells, modules, racks and systems. With this exposure, LTG was able to understand trends and stages in lithium-ion battery failures and develop products to provide early warning of thermal runaway by monitoring for the initial stages of failure. Additionally, LTG has recently entered a strategic alliance with Honeywell to help it create truly cutting-edge products and increase its outreach as lithium-ion batteries become a global standard in many different applications.

The third generation product will be released formally in 2021. The new monitor includes a well-rounded environmental sensing solution, which was incorporated after significant market demand and studying root causes of the string of South Korean battery fires in 2018 and the Arizona Public Service battery fire in 2019. Lack of granular environmental sensing was shown to be a potential root cause of these fires. The benefits of the third generation product line include:

  • Enhanced Safety – Detect problems even before an off-gas event (rising temperatures of a certain battery cluster)
  • Improved Battery Life – Ability to monitor and control humidity and temperature, which will extend battery life; helping with preventative maintenance
  • Cost Savings – Reduced installation cost – need one sensor vs. multiple; potentially reduce the team needed for monitoring and maintaining battery facility
  • Time Savings – Reduce installation time; reduce time involved in monitoring
  • Data and Information Availability – Information will be automatically delivered to emergency responders in case of an event

As lithium-ion batteries begin to fail, they increase internal cell pressure through a variety of mechanisms caused by thermal, electrical or mechanical abuse imposed on the cell. The pressure increase in the cell will eventually result in a venting of the internal gases – an off-gas event. If left unchecked the cell will eventually catch on fire during thermal runaway. The Li-ion Tamer off-gas detection technology is designed to detect when the cells vent gases, which typically occurs two to 30 minutes prior to a fire or thermal runaway. The incipient fault detection provided by this method of off-gas detection can alert the battery system that failure is imminent, and the system should be shut down to mitigate the risk of a system fire.

“Lithium-ion storage offers great potential to many industries but can also pose a significant risk if proper protection elements aren’t appropriately in place,” said Kyle Shen, CEO, Nexceris. “Our goal is to help our customers improve uptime of their facilities and quickly identify the source of a problem – and control it – before it escalates.”

Li-ion Tamer’s monitored fleet exceeds 1 GWhr of energy storage in more than 125 global projects with zero battery fires. Since its first utility-scale installation in 2017, Li-ion Tamer’s business has grown significantly and energy storage trends point to increasing demand for off-gas detection systems. The global energy storage industry is projected to grow 13 times its current size by 2024 from a 12 gigawatt-hour market in 2018 to a 158 gigawatt-hour market in 2024, equating to a $71 billion investment in storage systems alone.[1]
