Volvo Buses in project researching use of second-life electric bus batteries to store solar energy

Green Car Congress

In Viva housing cooperative, Riksbyggen, Volvo, Göteborg Energi and Johanneberg Science Park have created a unique system in which energy from solar panels on the roofs of the apartment buildings is stored in batteries that previously powered electric buses on route 55.

Organically synthesized porous carbon shows “exceptional” potential as Li-ion anode material

Green Car Congress

The new carbon shows electron conductivity, high porosity, the highest uptake of lithium ions of any carbon material to?date date and the ability to inhibit dangerous lithium dendrite formation. ion batteries (LIBs) with high capacity, excellent rate capability, long cycle life and potential for improved safety performance.

Georgia Tech researchers develop aluminum-foil-based anodes for all-solid-state Li-ion batteries

Green Car Congress

The team observed that the aluminum anode could store more lithium than conventional anode materials, and therefore more energy. In the end, they had created high energy density batteries that could potentially outperform lithium-ion batteries. Support is acknowledged from Novelis, Inc. Sloan Foundation.

Electrovaya launches Li-ion residential energy storage system; 3 kWh – 20 kWh

Green Car Congress

launched its lithium-ion energy storage system for home usage. The battery stores power from the grid or from solar panels and stores it for later household use. In some regions, utilities occasionally provide negative pricing to dump excess power when demand is very low, so users may actually be paid to store energy.

UNSW, H2Store to develop hydrogen storage for renewables; residential and commercial P2G

Green Car Congress

Professor Kondo-Francois Aguey-Zinsou and his team at UNSW’s School of Chemical Engineering have developed a system that provides cheap storage and transportation of hydrogen which they expect will provide a new alternative for energy storage within two years. We can actually store about seven times more energy than the current systems.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

And because such batteries could be installed and operated just like conventional solid lithium-ion batteries, without any of the auxiliary components needed for a lithium-air battery, they could be easily adapted to existing installations or conventional battery pack designs for cars, electronics, or grid-scale power storage.

Jülich, ORNL researchers advance high energy density iron-air batteries

Green Car Congress

Iron–air batteries, originally proposed in the 1970s, have theoretical energy densities of more than 1,200 Wh/kg; by comparison, present-day lithium-ion batteries come in at about 600 Wh/kg, and even less (350 Wh/kg) if the weight of the cell casing is taken into account.
