New solid-electrolyte interphase may boost prospects for rechargeable Li-metal batteries

Green Car Congress

Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase (SEI), according to Penn State researchers. In this project, we used a polymer composite to create a much better SEI. V Li|LiNi 0.5

Volvo Car Group testing lightweight structural energy storage material applied in trunk lid and plenum cover

Green Car Congress

A composite blend of carbon fibers and polymer resin is being developed that can store and charge more energy faster than conventional batteries can. The material combines carbon fibers and a polymer resin, creating a very advanced nanomaterial, and structural supercapacitors. Click to enlarge. Click to enlarge.

USC team develops novel organic redox flow battery for large-scale energy storage

Green Car Congress

Scientists at USC have developed a novel water-based Organic Redox Flow Battery (ORBAT) for lower cost, long lasting large-scale energy storage. These properties render quinone-based redox couples very attractive for high-efficiency metal-free rechargeable batteries, they found. Schematic of ORBAT. Click to enlarge. Electrochem.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

Not least of those considerations is energy storage [and generation].” Solar won’t work for nocturnal animals or creatures in low-light environments. A little device that harvests energy from a runner’s evening jog clearly is not designed for a massive bison, which can weigh up to a tonne.

Dow Kokam and PVI partner on fully electric refuse trucks

Green Car Congress

The modular plug-in battery pack was also designed to be interchangeable or accommodate a partial recharge between two daily service rounds, thus doubling performance capabilities. Dow Kokam was established in 2009 to develop and manufacture advanced energy storage technologies for the transportation and other industries.
