An airbag for battery packs: PyroPhobic says its unique thermoplastics will stop thermal runaway

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 »

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 »

Webasto launches modular battery system, thermal management, and charging stations

Automotive supplier Webasto showcased its modular battery system, thermal management system, and charging station at the recent SEMA show in Las Vegas. The CV standard battery system is available in 400 V and 800 V versions. Each battery features 35 kWh of energy. Up to 10 packs can be used for a combined 350 kWh…. 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 »

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 »
