Researchers at Australia’s Monash University have developed a compact graphene-based supercapacitor device that lasts as long as a conventional battery, an advance with the potential to bring next-generation energy storage a step closer. Professor Dan Li of the Department of Materials Engineering and his team published their work this week in Science. Supercapacitors (SCs) are… Read more »

OXIS Energy bets on lithium-sulfur
Though it may have a stinky reputation, sulfur could set EVs on the path to total ICE replacement if energy-dense, low-weight lithium-sulfur batteries become the norm. British-based OXIS Energy is banking its business on it. If American clean energy industries are to take full advantage of the emerging lithium-sulfur (Li-S) battery chemistry, they just may… Read more »
Oak Ridge researchers give solid Li-ion electrolytes a new spin
Their novel approach offers an advantage in terms of safety and also results in a broad (5 V wide) electrochemical window.
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 »
DOE releases EV Everywhere Grand Challenge Blueprint
The report sets priorities, including numerical objectives, in five key technical areas: batteries, drive systems, vehicle lightweighting, climate control and charging infrastructure.
CalBattery’s new Si-graphene anode triples Li-ion battery capacity
California Lithium Battery, a finalist in the DOE’s 2012 Start Up America’s Next Top Energy Innovator challenge, has announced the record-setting performance of its new “GEN3” silicon graphene composite anode material for lithium-ion batteries (LIBs). Independent test results in full cell LIBs reveal an energy density of 525 Wh/kg and specific anode capacity 1,250 mAh/g. In… Read more »
Researchers use world’s thinnest material to create quick-charging Li-ion anode
Yet another exciting advance in battery technology was announced this week. Researchers at Rensselaer Polytechnic Institute, led by nanomaterials expert Nikhil Koratkar, made a sheet of paper from the world’s thinnest material, graphene, then zapped the paper with a laser or camera flash to blemish it with countless cracks, pores, and other imperfections. The result… Read more »
Microvast designs batteries, builds buses, and partners with utilities
Microvast is the largest battery company you’ve probably never heard of. That’s because they are their own best customer. Instead of pitching their proprietary lithium–titanate technology to vehicle builders, the company identified a well-suited niche for their batteries and set out to demonstrate a sustainable model. Primarily a research and development focused chemical company, Microvast… Read more »
Boston-Power to supply batteries to Beijing Electric Vehicle Company
Boston-Power, Inc. announced this week that it has entered a multi-year agreement to provide lithium-ion battery systems to Beijing Electric Vehicle Company (BJEV), the electric vehicle delivery arm of Beijing Automotive Industry Company. Boston-Power’s Swing 5300 cells will be used in multiple BJEV models and brands, beginning with the C70 sedan, which is based on… Read more »
New process extracts multiple battery anodes from a wafer of silicon
The process uses silicon to replace graphite as an element in Li-ion cells, which could lead to longer-lasting, more powerful batteries.
