The GM China Advanced Technical Center (ATC) in Shanghai announced the operation of its magnesium alloy Vertical Squeeze Casting (VSC) machine—the first designed for developing next-generation magnesium castings. GM said that this achievement marks a breakthrough in its lightweight materials research.
Squeeze casting is a process in which molten metal is introduced to casting cavities with minimum turbulence and then solidifies under very high pressure (typically above 100 MPa) within closed dies. The absence of turbulent metal flow, aided by the high applied pressure, can suppress gas porosity, notes Ohio State University Professor Alan Luo in a 2013 review of magnesium casting technologies.

Driven by tighter emission standards in Europe, worldwide production of plug-in electric vehicles(PEVs)—including both battery-electric (BEV) and plug-in hybrid (PHEV) models—will increase by 67% this year, according to IHS Automotive, driven by Polk. The jump in the PEV market this year contrasts with an expected 3.6% rise in global manufacturing of all motor vehicles expected in 2014.
Total production of PEVs is projected to rise to more than 403,000 this year, up from slightly more than 242,000 in 2013. Growth will accelerate sharply from the 44% increase in 2013, based on data from the new IHS Automotive Hybrid-EV Portal. In December 2013, IHS projected total global automotive sales in 2014 of 85 million, roughly resulting in an expected approximate 0.5% share for PEVs in the global market this year.
DOE to award up to $12M for technologies to produce renewable carbon fiber from biomass
The US Department of Energy (DOE) will award (DE-FOA-0000996) up to $12 million in funding to advance the development of a cost-competitive pathway to produce high-performance carbon fiber for vehicle lightweighting from renewable non-food biomass. Reducing a vehicle’s weight by just 10% can improve fuel economy by 6% to 8%.
Carbon fiber composites are lightweight, yet strong, materials that can greatly improve vehicle fuel efficiency when incorporated into structural and non-structural components. Carbon fibers are polymers that are typically made from petroleum and natural gas feedstocks (propylene and ammonia, respectively) that react to form acrylonitrile (ACN) which is then polymerized and spun into polyacrylonitrile (PAN).

Ford Motor Company has added its near-dry machining process—Minimum Quantity Lubrication (MQL)—to six plants globally, a number that will nearly double in the next few years.
Machining metal pieces generates friction and heat. Conventional wet machining floods the work piece with metal-working fluids, requiring large amounts of fluid to cool and lubricate the cutting tools. MQL eliminates conventional flood coolant from the machining processes, lubricating cutting tools with a fine spray of oil directed exactly when and where it is needed. MQL reduces oil mist generation; biological contamination of coolant; waste water volume; costs for capital equipment; and regulatory permitting. MQL also improves recycling and transport of coolant contaminated chips.

Ultrasonic welding in the battery pack for the Cadillac ELR
August 02, 2013
GM is using ultrasonic welding in the 16.5 kWh battery pack in the new Cadillac ELR extended-range electric luxury coupe that goes on sale in North America in early 2014 (earlier post). The battery-specific welding process is a result of collaboration among GM’s Manufacturing Systems Research Lab, Advanced Propulsion Center, and Brownstown Battery Assembly plant near Detroit. GM first applied the process on the Chevrolet Volt and further refined it for ELR.
Ultrasonic welding uses specialized tools called an anvil and horn to apply high-frequency vibrations to the battery’s copper and aluminum electrodes. This introduces oscillating shear forces at the interface between two metals, causing elastoplastic deformation at the interface. This ultimately results in a structure similar to that of a diffusion weld that does not require melting-point temperatures or joining material such as adhesives, soldering or fasteners.

Renault makes public its lifecycle study of Fluence ICE vs Fluence EV
July 11, 2013
|Renault’s comparison of the carbon footprint of EV and ICE vehicles over production, operation and end of life. The EV footprint (Fluence Z.E.) is shown with both UK and French grid mixes. Click to enlarge.|
Renault recently made public the findings of an internal study, published first in October 2011, detailing and comparing the lifecycle assessments (LCAs) of the battery-electric and two internal combustion engined versions (gasoline and diesel) of the Renault Fluence. The study used the series production versions launched in 2011, with the assumption of operation for 150,000 km (93,205 miles). (Since the BEV version has a shorter range, Renault noted, the way in which the miles are accumulated could differ from that of the ICE vehicles.)
The publication gives the opportunity for an “apples-to-apples” comparison between the environmental impacts of the two types of powertrains: same manufacturer, same model, same boundary conditions. Nevertheless, Renault noted, the study is contrasting a new technology (EVs) with a well-developed one; “environmental progresses are expected in a short term thank to key process improvement and massification of the production.”

|Correlation between weight reduction and life cycle primary energy demand for (a) component and (b) total vehicle scenarios. Credit: ACS; Kim and Wallington. Click to enlarge.|
While reducing vehicle weight (lightweighting) by replacing steel and iron with alternatives such as aluminum, magnesium, and composites decreases fuel consumption and greenhouse gas emissions during vehicle use, it can increase energy consumption and GHG emissions during vehicle production.
Hyung Chul Kim and Timothy J. Wallington at Ford Motor’s Systems Analytics and Environmental Sciences Department set out to clarify the lifecycle benefits of vehicle lightweighting in a meta-analysis of previously published life cycle assessments (LCAs). While numerous studies assay the benefits of lightweighting, the wide variety of assumptions used makes it difficult to compare results from the studies, the pair noted in their paper, published in the ACS journal Environmental Science & Technology.

PARC launches ARPA-E-funded co-extrusion printed battery project
April 30, 2013
PARC, a Xerox company, has launched a project with the US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) under the 2012 Open Funding Opportunity. (Earlier post.) The Printed Integral Battery Project will leverage a PARC invented co-extrusion (CoEx) technology (earlier post) to demonstrate a lithium-ion battery manufacturing process that deposits the entire functional battery in a single pass.
The conventional lithium-ion battery manufacturing process requires that the two electrodes of a battery be made in two separate steps, and then combined together in a third step—each step adding cost that contributes to the high price of the final product. PARC’s Printed Integral Battery deposits the entire battery cell—cathode, separator, anode—in one single pass.
