Researchers use paper-folding technique to increase energy density

Could the secret to unleashing the electromobility revolution be…origami? Researchers at Arizona State University have shown that paper-folding concepts can be applied to Li-ion batteries to build devices with higher areal energy densities. In a paper published in the ACS journal Nano Letters, Qian Cheng and the team described how they built a battery using… Read more »

Dual battery pack could give next-generation Tesla unprecedented range

Is Tesla working on a new type of hybrid pack that combines two different battery technologies to deliver a huge increase in range? This question has been floating around the discussion groups for a few months, but several outlets reported it as breaking news this week after a couple of stock analysts discovered the story… Read more »

Australian researchers announce supercapacitor breakthrough

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 »

Ultracap manufacturer raises $15 million in funding

Ioxus, a manufacturer of ultracapacitor technology, has raised $15 million in Series C funding from investors. The Westly Group, a venture capital firm based in Menlo Park, California, led the financing. The company plans to use the funds to further research and development, expand manufacturing capabilities and increase sales and marketing operations. Ultracapacitors (aka ultracaps… Read more »

ABB announces flash charging electric bus pilot in Geneva

ABB has developed a new flash charging system for city buses, and is working with the city of Geneva’s public transport company and electric power utility SIG on a pilot project. The TOSA (Trolleybus Optimisation Système Alimentation) will be deployed for the first time on a 135-passenger electric bus. The system enables onboard batteries to… Read more »

Ultracapacitors creep into automotive

Maxwell looks to leverage its early ultracapacitor experience into a ubiquitous, low-cost, high-volume complement to batteries. Power sources like internal combustion engines and advanced battery packs work great as continuous suppliers of energy. But during the highest peak loads, both sacrifice efficiency attempting to meet the power delivery demands. And pushing these devices to their… Read more »

It’s in the details: Digatron Firing Circuits’ new stop-start testing rig

Digatron Firing Circuits’ new stop-start testing rig examines the limitations of lead-acid batteries and the inadequacy of traditional static tests. As the battery in a stop-start system ages, the fuel efficiency advantages are curtailed. It’s a real problem found in some first-generation systems, and has led many to question the methodology used in urban-efficiency tests…. Read more »
