Novel nanomaterial to replace graphite in lithium-ion batteries
Porous nanostructured microspheres made of copper, iron, and iron oxide were used by an international research team as negative anode material in lithium-ion batteries. The new technique is claimed to provide three times more capacity than batteries based on graphite anodes.

NREL looks at opportunities in lithium-ion battery recycling
U.S. scientists assessed the reuse and recycling of large-format lithium-ion batteries for electric vehicles and energy storage systems and found there is plenty of room for improvement.
Trina Solar enters storage business
The module manufacturer’s new storage unit, Trina Storage, aims to create innovative solutions for the combination of photovoltaics and storage, grid services and other applications.
Vehicle-integrated PV reduces EV charging time in sunny regions by 40%
Dutch scientist Bonna Newmann spoke with pv magazine about the present and future of vehicle-integrated PV from a technological and economic perspective. Solar panels installed on cars could have a payback time of only three or four years and ensure 10,000 km of pure PV-generated road travel per year, she said. Furthermore, if you live in a sunny place, you can drive an electric car with solar panels for weeks during summertime, without the need for recharging, she pointed out.
Storage and PAYG critical to deployment of African off-grid renewables
The former need not necessarily relate to conventional lithium-ion batteries, however, as a recent webinar staged by Solarpower Europe and EU body GET.invest discovered.
