Yale team develops dendrimer-graphene oxide composite film for improved cycling of Li-sulfur batteries

23 March 2017

Researchers at Yale University developed an ultrathin functionalized dendrimer–graphene oxide composite film that can be applied to virtually any sulfur cathode in a Li-sulfur (Li-S) battery system to alleviate capacity fading over battery cycling without compromising the energy or power density of the entire battery.

Sulfur electrodes coated with the composite film exhibit very good cycling stability, together with high sulfur content, large areal capacity, and improved power rate. The film design provides a new strategy for confining lithium polysulfides. A paper on their work is published in Proceedings of the National Academy of Sciences (PNAS).

Lawrence Livermore Lab researchers significantly boost truck fuel efficiency through improved aerodynamics

23 March 2017

Lawrence Livermore National Laboratory (LLNL) researchers, as part of a Navistar SuperTruck I team, helped design a new type of tractor trailer truck that improves fuel economy by 124%, compared to heavy vehicles on the road today.

Seventy-four percent out of the 124% improvement comes from aerodynamic enhancements, while the rest comes from engine efficiency, tire rolling resistance, light weighting and other advancements. On a track test, the new SuperTruck I vehicle achieved 13 mpg (18.1 l/100 km), compared to a typical truck on the road that gets around 5.8 mpg (40.5 l/100 km).

An OPEC Deal Extension Isn’t As Simple As It Sounds

23 March 2017

by Tsvetana Paraskova for Oilprice.com

It’s been six months now that oil prices have been reacting to OPEC, first to the possibility of an agreement, and then to the production cut deal itself, forged by OPEC to rebalance the market. The deal—initially aired as “an agreement to agree on a deal” in September and signed at the end of November—will likely impact the market for at least the next six months.

The agreement clearly states that it is production that OPEC producers are vowing to cut, but Iraqi oil minister Jabbar al-Luaibi has recently claimed—rather emphatically—that it is exports, not production, that serve as the baseline for the cuts. And according to Iraq, the agreed-upon cuts have been all about exports all along.

ICCT: incremental technology can cut vehicle CO2 by half and increase fuel economy >60% through 2030 with ~5% increase in price

22 March 2017

With the EPA re-opening its Mid-Term Review of GHG standards for 2022-2025 for light-duty vehicles (earlier post), and with NHTSA yet to weigh in on its Mid-Term evaluation of fuel economy standards for the same period, a team from the International Council on Clean Transportation (ICCT) has published a report analyzing emerging vehicle efficiency technologies; their ability to achieve lower emission levels; and their costs in the 2025–2030 timeframe.

Starting from a baseline 26 mpg (9.04 l/100 km) in 2016, the The ICCT team assessed increased consumer label fuel economy (as opposed to the regulatory test fuel economy) to 35 mpg (6.71 l/100 km) in 2025 and to 42–46 mpg (5.6-5.11 l/100 km) (under three scenarios) by 2030. These fuel economy levels are achieved based on a sustained 4%–6% annual reduction of fuel use per mile with incremental technology additions that do not compromise vehicle size or utility at an incremental cost of $800–$1,300 from 2025 to 2030. The resulting trajectory would reduce CO2 emissions by half and increase fuel economy by more than 60% from 2016 through 2030. Based on a detailed analysis of the efficiency technologies used to achieve these lower CO2 emission levels, the ICCT study concludes that vehicle prices would increase by about 5% by 2030.

The interdependency of autonomous electric vehicles and wireless charging

22 March 2017

Conference presentations at the 4th International Electric Vehicle Expo this week in Jeju, South Korea, explored issues related to automated driving systems, electric vehicles and infrastructure. Specifically, two presentations from KAIST (Korea Advanced Institute of Science and Technology) and SAE International addressed the interdependence of standardization, autonomous electric vehicles and wireless charging.

The issue with conductive charging is though there are plenty of standards, unfortunately many of these standards are simply not compatible. This incompatibility hurts not only the infrastructure, but also the commercialization of the electric vehicle as the customer does not accept not being able to go to a specific charging [spot],” said Dr. Uooyeol Yoon of KAIST.

TU Graz researchers identify singlet oxygen as major cause of deleterious side reactions in Li-air batteries; suggested approach to counter

21 March 2017

Researchers led by a team from Graz University of Technology (TU Graz) in Austria have shown that singlet oxygen (1O2) forms in the cathode of a Li–O2 battery during discharge and from the onset charge, and that it is responsible for a major fraction of side products that cause fast ageing in the battery. A paper on their work is published in the journal Nature Energy.

The paper also suggests an initial approach as to how the storage cell can protect itself from the reactive oxygen species. Singlet oxygen is the main cause of ageing in biological cells. To counter this, nature uses an enzyme called superoxide dismutase to eliminate superoxide as a free radical. The researchers identified a class of molecules that can provide a function for the Li-O2 battery similar to that of the enzyme superoxide dismutase in biological systems.
