Energy storage provider Cadenza Innovation has raised over $5 million in growth capital, which it will use to expand product development, secure additional certifications, extend initial deployments and make key new hires. Cadenza says its novel pack architecture enables longer range in a smaller footprint, and its integrated fire protection eliminates fires caused by thermal… Read more »
Search Results Found For: "thermal runaway"
New material shuts down batteries at high temperatures and restarts when it cools
Stanford researchers have invented a new technology that could eliminate thermal runaway in high-energy-density batteries. Thermal runaway refers to a chain reaction in which an increase in temperature causes further increases in temperature and uncontrollable release of energy. In “Fast and reversible thermoresponsive polymer switching materials for safer batteries,” published in Nature Energy, Professor Zhenan Bao and… Read more »
AllCell to supply solar-powered EV charging stations to Jordan
The Middle East is not the first region that comes to mind as an EV hotspot. However, the desert kingdom of Jordan has a plan to get charged. Jordan has eliminated import taxes on EVs. The city government of Amman, the capital, plans to buy 50 EVs for its fleet, and a city taxi operator… Read more »
AutoLion Li-ion battery simulation software claims a unique modeling technology
Super modeling: EC Power’s AutoLion claims unique technology, reliable results and extraordinary savings in development time and cost With battery technology being one of the key bottlenecks slowing down the widespread adoption of electric vehicles, Pennsylvania’s growing startup EC Power proposes a tantalizing offer to battery developers: cut your product development cycle by around 20 percent, and… Read more »
Analyzing heat-driven decay in nickel-cobalt-aluminum batteries
A set of three recent studies funded by the Korean government investigated a family of lithium-ion batteries composed of nickel, cobalt and aluminum. NCA batteries offer high energy density, but degrade significantly with each charge/discharge cycle. The high heat of vehicle environments can intensify the degradation, and even cause complete battery failure. Researchers at the… Read more »
Voltabox begins building Li-ion battery packs in Texas
Three Li-ion battery chemistries, the speed of its software and hardware systems configuration and the automotive legacy of Voltabox make this newly-landed American spin-off company a player in the realm of rechargeable batteries for public transit and heavy industrial vehicles. Austin, Texas is known for many things: music festivals, barbequed ribs, the Texas Longhorns, filmmaker… Read more »
Freudenberg Group’s new line of Li-ion battery separators
The separator is a critical component of a battery. It provides a barrier between the anode and the cathode while enabling the exchange of ionic charge carriers from one side to the other. For over 40 years, the Freudenberg Group has been producing separators for nickel-based batteries, such as the nickel-metal hydride (NiMH) cells widely… Read more »
Proterra to use Toshiba SCiB batteries in its next-generation electric bus
Proterra has selected Toshiba as the battery supplier for its next-generation electric bus. Toshiba’s SCiB batteries feature a lithium titanate oxide chemistry, making them resistant to thermal runaway and lithium metal plating. The 20 Ah prismatic cells have nominal voltage of 2.3 V, gravimetric energy density of 90 Wh/kg and volumetric density of 177 Wh/L…. Read more »
A closer look at how batteries fail
A lot of research has been done to improve lithium-ion battery safety, cycle life and power output over a range of high and low temperatures, yet understanding the fundamental processes and degradation mechanisms in Li-ion batteries remains a challenge. To understand the degradation processes of lithium-ion batteries, it is important to understand how they operate…. Read more »
