Fiat Chrysler electrifies the Ram 1500 truck


Unveiled at the 2018 Detroit auto show, the 2019 Ram 1500 has shed 100kg and added e-torque power. Available with a 5.7-liter Hemi V8 or a second-generation 3.6-liter Pentastar V6 engine, the 1500 uses mild-hybrid capability to recapture energy during deceleration to enable start/stop function as well as short-duration torque addition.

Mercedes-Benz unveils its revamped G-Class


The all-new G-Class makes its public debut at the Detroit auto show in the USA this month in G550 form. Completely redeveloped and fitted with a 4.0-liter V8 biturbo gasoline engine offering 427ps and 450 lb-ft of torque at 2,000rpm to 4,750rpm, despite near-identical looks to its predecessor plenty has changed for the Mercedes-Benz SUV.

Perpetuus and Oxis Energy to develop graphene-enabled battery electrode technology

A pair of UK companies, Perpetuus Carbon Group and Oxis Energy, will collaborate on the development of graphene-enabled electrodes for the next generation of lithium sulfur (Li-S) battery technology. Oxis Energy is a leading developer of Li-S technology, claiming that these batteries have a theoretical energy density five times greater than conventional lithium-ion batteries.

Using its proprietary plasma technology, Perpetuus is able to insert molecules into layered solids such as graphene (known as intercalation) to the very high levels required for enriched electrode materials. Together with Oxis Energy technology, these advanced electrode materials will deliver the next generation of high performance batteries offering energy densities in the order of 400Wh/kg.

This is significantly higher than current Li-ion batteries can achieve. It is also much more cost effective as it will enable cars to undertake journeys of 400-500 miles (640-800km) on one battery charge.

Commenting on the collaboration, Huw Hampson Jones, CEO of Oxis said, “Perpetuus has a unique ability to produce industrial quantities of the nano-engineered electrode materials that will significantly extend the cycle life of Li-S batteries.”
“There is no doubt that OXIS Li-S technology has the ability to be significantly superior to current Li-ion batteries,” agreed Perpetuus CEO John Buckland. “I hope this collaboration will pave the way for the UK to be the center of Li-S battery manufacturing. Perpetuus plasma technology could ensure the UK becomes the manufacturing center to a vast number of graphene-enabled products over the next few years. In the coming months, we hope to be announcing further collaboration and development agreements with other UK businesses, utilizing our nano surface engineered graphene materials.”
