Polymer-graphene nanocomposites as high-rate “green” electrodes for Li-ion batteries

Green Car Congress

Besides the conventional inorganic materials [for Li-ion battery cathodes], organic cathode materials, including small molecules and polymers, have also been emphasized recently as a new generation of “green” lithium battery electrodes due to their sustainability and environmental benignancy. graphene nanocomposites.

Sandia researchers confirm mechanism by which Li ions move in and out of LFP electrodes

Green Car Congress

Using X-ray and electron microscopy, researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate (LiFePO 4 , or LFP). The research is reported in a paper in the ACS journal Nano Letters.

JCESR team identifies new mechanism hampering Mg-ion batteries; unforeseen reactivity

Green Car Congress

Rechargeable magnesium batteries are of great interest as potential “beyond Li-ion” systems for extended electric vehicle range. Because magnesium is divalent, it can displace double the charge per ion (i.e., Mg 2+ rather than Li + ). As an element, magnesium is more abundant than lithium, and more stable. Earlier post.)

Volkswagen targeting 5% of Jetta sales in US with new sporty Hybrid model; expected 45 mpg combined

Green Car Congress

Volkswagen is holding media drive events this week for the sporty new 2013 Jetta Turbo Hybrid ( earlier post ), which features the second version of a Volkswagen gasoline-electric hybrid drive system: a 1.4L kWh Li-ion battery pack. The Jetta is the first Volkswagen hybrid with a Li-ion pack (cells from Sanyo).

Audi highlights its range of electrification efforts; Q7 diesel PHEV, A7 fuel cell PHEV, BEV, 48V and more; 750 Wh/l by 2025

Green Car Congress

In ten years’ time, Audi aims to offer all new models with mild hybrid technology, with the exception of the e-tron lineup. The lithium-ion battery comprises 168 prismatic cells and is liquid-cooled. Its emphasis is on lithium-ion battery systems, which are put together using a flexible, modular concept. With a capacity of 17.3
