Pellion Technologies, a startup commercializing magnesium-ion battery technology ( earlier post ), announced an investment by Motorola Solutions. Because magnesium is divalent, it can displace double the charge per ion (i.e., Mg 2+ rather than Li + ). As an element, magnesium is much more abundant than lithium, and more stable.

Researchers have achieved a significant boost in the storage capacity of magnesium-ion batteries through a new design for the cathode and a new understanding of the electrolyte. Magnesium ion is known to be hard to insert into a host. More than that, magnesium ions produced in that way move extremely slowly in the host.

Schematic of hybrid anode placed in a Li–S battery. The graphite/Li connected in parallel forms a shorted cell where the graphite is always lithiated at equilibrium and maintains a pseudo-equal potential with the Li metal. Alternative energy-storage systems with much higher theoretical specific energy are needed.

Qichao Hu in the company’s presentation at the US DOE’s 2012 National Clean Energy Business Competition, SolidEnergy technology can potentially deliver energy densities of up to 800 Wh/kg—twice the energy density of state-of-the-art batteries and four times the energy density compared to conventional lithium-ion batteries.

Zinc-air technology, although offering high energy density—about twice the gravimetric density (Wh/kg) and three times the volumetric density (Wh/L) of Li-ion technology—has been generally limited to low-power, non-rechargeable applications. 2013.10.073. Electric (Battery) Fuel Cells'

The difference lies in a more powerful electric motor, increased energy storage and equipment for overhead conductive opportunity charging. Recharging takes approximately 6 minutes at end stations. Hamburg, Luxembourg and Stockholm will implement the new bus system in 2014 and 2015.

When paired with lithium metal anode to form rechargeable lithium?sulfur sulfur (Li?S) S) batteries, the theoretical specific energy density can be as high as 2600 Wh kg ?1. A major bottleneck is the slow charge transfer kinetics resulting from poor electronic conductivity of sulfur and the final discharge product, Li 2 S.

Hyundai’s position on fuel cell vehicles is that they alleviate the limitations of traditional battery-electric vehicles with respect to range and refueling (recharging) time. The Tucson Fuel Cell began mass production for the US market in April 2014 at the Ulsan, Korea assembly plant that also manufactures the Tucson gasoline-powered CUV.

In that context, he said that he sees “ great potential ” in solid-state batteries, which possibly could boost EV range to as much as 700 km (435 miles), representing a volumetric energy density of about 1,000 Wh/l. Current Li-ion batteries, with about 260 Wh/l are enabling a range of some 190 km (118 miles), he said.

Researchers from the UK and France are proposing a unified mechanism for the reduction of O 2 at the cathode of a Li-air (Li-O 2 ) battery. At the positive electrode, on discharge, O 2 enters the pores of the electrode, where it is reduced and combines with the Li + ions from the electrolyte to form solid Li 2 O 2.
