Batteries

The joint study reports that the research team has opened new doors in the development of high energy-density batteries capable of meeting rapidly growing energy storage needs by overcoming the current temperature limitations of fluoride-based battery technology and by demonstrating the room-temperature operation of fluoride-ion based energy cells.

Amprius Inc is supplying advanced lithium ion cells to the Airbus Defence and Space Zephyr Program. Using Amprius' cells, which contain a 100% silicon anode, the Zephyr S flew more than 25 days, setting a new endurance and altitude record for stratospheric flight.

A research team has reported that adding water into electrolyte improves the function of vanadium oxide, which is one of positive electrode materials in calcium-ion batteries.

When completed, it will be the largest power storage unit connected directly to the grid in mainland France. With a 6 MW / 6 MWh power rating, the unit will use its storage capacity to perform frequency regulation services for the grid, helping keep any frequency deviation in check.

A new technology uses textiles as battery cells, which significantly improves the amount of energy that can be stored, meaning that the new battery could potentially power an object as energy intensive as a laptop or smartphone.The technology enables the use of smaller battery cells, allowing for larger capacities.

Better batteries for a greater range of electric vehicles - this is the goal of the "EMBATT-goes-FAB" project sponsored by the Federal Ministry for Economic Affairs and Energy. For that reason, the four project partners thyssenkrupp System Engineering GmbH, IAV GmbH, Daimler AG and the Fraunhofer Institute for Ceramic Technologies and Systems IKTS are developing bipolar batteries and processes for their fabrication.

The Swiss battery system manufacturer ecovolta has developed a standardised Li-ion traction battery which significantly cuts the time and expense needed to bring electric vehicles to the serial production stage.

Alliance Ventures, the strategic venture capital arm of Renault-Nissan-Mitsubishi, has announced that it has invested in the latest round of funding in Enevate Corporation, an advanced lithium-ion battery technology company based in Irvine, California.

A major factor holding back development of wearable biosensors for health monitoring is the lack of a lightweight, long-lasting power supply. Now scientists report that they have developed a method for making a charge-storing system that is easily integrated into clothing for "embroidering a charge-storing pattern onto any garment."

Scientists' method quenches lithium metal dendrites in batteries that charge faster, last longer.
