Safe and sustainable cities will depend on lithium-ion batteries to power our modern lives. But what are the costs?
Lithium-ion batteries in your favorite devices make our daily lives possible, but they also come with risks. Join the search for safer solutions.
Describe why the content in the resource matters. What the resource is.
Lithium-ion batteries are powerful and convenient, but they can experience thermal runaway. This reading examines how thermal runaway of e-bikes in New York City became a safety concern and how the city took CHARGE of safety.
Read this document to understand: How does thermal runaway in e-bikes occur, and how can communities and cities stay safe?
Be sure to explore the pathway Xplorlabs: Science of Thermal Runaway and ULRI’s Take C.H.A.R.G.E of Battery Safety that shares research-based background knowledge and insights about battery safety.
