Engineers have been searching for ways to mitigate the risk of fire with Li-ion batteries since the technology was first commercialized. Chemists are creating new cell formulations that are less prone to problems, electronics experts are designing fail-safe battery management systems, and mechanical engineers are building complex cooling and fire suppression systems. A common rule… Read more »
Results for: "thermal runaway"
New separator membrane could enable faster charging, eliminate thermal runaway
Researchers from Ohio State University have designed a thin plastic membrane that could improve the charging speed of current batteries, and possibly enable a new type of battery as well. In a study published in the journal Energy & Environmental Science, assistant professor Vishnu-Baba Sundaresan and doctoral student Travis Hery argue that current battery designs… Read more »
Can phase change material mitigate thermal runaway in Li-ion packs?
(This article originally appeared in Charged Issue 6 – JAN/FEB 2013) AllCell Technologies’ new phase change thermal management material If you have spent time at any of the EV industry trade shows, you’ve probably heard the term thermal runaway. It refers to a chain reaction in which an increase in temperature causes further increases in temperature and uncontrollable… Read more »
AllCell uses phase change materials to prevent Li-ion thermal runaway propagation
AllCell Technologies received a new US patent covering the use of phase change materials (PCM) to prevent thermal runaway propagation in electrochemical devices such as lithium-ion batteries. AllCell has developed a proprietary composite material composed of a conductive matrix impregnated with various PCMs that extends the cycle life of lithium-ion cells and can prevent the… Read more »

Free eBook: Battery thermal management in hybrids & EVs
Sponsored by Elkem Thermal management is an important discussion topic in battery-powered systems when considering insulation, heat and power transfer, conduction and convection, in order to maintain the battery pack temperature within a tight tolerance to reduce thermal runaway. Thermal management of batteries in H&EVs is essential for the effective operation of motors in all… Read more »
Quantifying battery risks and thermal safety
Exponent engineers on battery risks and thermal safety: If you can’t measure it, you can’t manage it. Any type of energy storage technology has some risk associated with the unanticipated release of stored energy. Failure of a pumped-hydro storage system, for example, can lead to flooding. Hydrocarbon fuels like gasoline, diesel or methane can ignite into flames…. Read more »

Presented by Donaldson experts Jake Sanders and Johan Begine, this webinar will discuss the importance of proper venting for battery packs… Read more »
BYD says its new Blade Battery offers far lower risk of fire
The popular discussion of EVs tends to center on range, and this has led battery makers to focus on increasing energy density—some would say, at the expense of other equally important attributes such as longevity and safety. Chinese EV giant BYD has introduced a new Blade Battery, which is designed to “bring battery safety back… Read more »
How to maximize safety in advanced battery systems
By Markus Beck, Sensata Technologies In advanced battery systems, the quality of the power electronics helps determine the quality of the final product, its level of functionality, and its reliability. This is emphasized in the latest battery power management and charging systems that use wide-bandgap semiconductors and improved power topologies. In such advanced electronics, if… Read more »
