The latest advance in lithium-sulfur technology comes courtesy of a research team from Samsung and the University of Rome, who have built a solid-state Li-S battery with a capacity (∼1600 mAhg−1) approaching the theoretical value and Coulombic efficiency approaching 99%. In a paper published in the Journal of The Electrochemical […]

Ioxus has launched its iMOD X-Series, a family of 22 ultracapacitor modules that are designed to simplify system design and installation for end users by offering a wide array of possible mounting configurations. The new modules use off-the-shelf T-slots to mount from any side in any configuration. They feature internally […]

SolidEnergy, an MIT spin-out company commercializing solid electrolyte technology, plans to release a 20 Ah EV battery in 2017, which it says will offer more than two times the range of current Li-ion batteries. The core of SolidEnergy’s technology is a Solid Polymer Ionic Liquid (SPIL) electrolyte, which enables the […]

A new high-performance, high-energy-density lithium-tellurium (Li-Te) battery system — based around a Li-metal anode and a Te-based cathode — was recently developed by researchers at the Kumoh National Institute of Technology in Korea. The mechanically reduced (MR) Te/C nanocomposite electrode material that the researchers created shows “high energy density, excellent […]

Those doggone dendrites are a bane of battery builders. These pesky fern-like growths can form on the surfaces of anodes during cycling, reducing battery life or even causing a catastrophic short circuit – this is how the battery fires on the Boeing 787 are thought to have started. A team […]

Battery-maker Energy Power Systems plans to establish a high-volume manufacturing facility in Pontiac, Michigan. The new 150,000-square-foot facility will produce batteries for use in start/stop and micro-hybrid vehicles; utility-scale distributed energy storage; renewable energy integration; and fast-charging infrastructure for EVs. Full-scale production is expected to begin in early 2016. Initial […]

A team from the University of Waterloo in Canada and BASF has developed a way to stabilize cathodes in lithium-sulfur batteries, significantly improving performance and cycle life. Li-S batteries offer high theoretical energy density and low cost, due to the high natural abundance of sulfur. However, the insulating nature of […]

The US Advanced Battery Consortium (USABC) has awarded a $299,000 contract to Seeo Inc. of Hayward, California. The nine-month technology assessment program will focus on testing of Seeo’s elevated-operating-temperature solid polymer battery modules. Under the contract, Seeo will deliver its DryLyte battery modules to USABC for testing and third-party validation. […]

Johnson Controls is adding a lithium titanate battery to its line of automotive battery offerings. The new 12-volt technology, the product of a collaboration with Toshiba, is designed to power Advanced Start-Stop vehicles. “Johnson Controls is pursuing opportunities to develop evolutionary low-voltage energy storage systems that will help our customers […]

While the mythology that currently surrounds Nikola Tesla does contain a lot of very fanciful elements, there’s no doubt that the man had a mind that was well suited towards the creation of technological “marvels.” The man has certainly left his mark on the world of modern technology — which […]

Emerging materials such as gallium nitride (GaN) and silicon carbide (SiC) will eventually displace silicon in power electronic applications, according to a new report from Lux Research, which forecasts that the market for GaN power electronics will reach $1.1 billion, about 5% of the total market, by 2024. While silicon […]

While lithium-ion is the chemistry of choice for EV batteries, almost every ICE vehicle made today still uses the ancient lead-acid battery technology for its 12-Volt starter battery (Porsche and a couple of other makers of high-performance cars offer lithium-ion starter batteries). Auto OEMs and battery providers want to preserve […]
