ORNL breakthrough could enable wider application of graphene composites

Graphene, a two-dimensional hexagonal lattice of carbon atoms, has great potential in a number of EV-related applications, including anodes, lithium-sulfur batteries and ultracapacitors. With current technology, however, it’s impractical to use on a large scale, and researchers have been limited to using small flakes of the material. Now a team of researchers at the DOE’s… Read more »

ORNL researchers develop Virtual Integrated Battery Environment design tool

As part of the DOE’s Computer Aided Engineering for Batteries (CAEBAT) project, scientists at the Oak Ridge National Laboratory (ORNL) have developed an open-architecture battery modeling framework that integrates multi-physics and multi-scale battery models. The Virtual Integrated Battery Environment (VIBE) allows researchers to test lithium-ion batteries under different simulated scenarios. The physics phenomena of interest… Read more »

ORNL team demonstrates high-voltage solid-state battery with impressive cycle life

Researchers at the Oak Ridge National Laboratory have demonstrated a solid-state high-voltage (5 V) lithium battery with an extremely long cycle life (10,000 cycles) and high Coulombic efficiency (99.98%). The solid electrolyte enables the use of high-voltage cathodes and lithium anodes with minimal side reactions. The energy stored in a battery of a given size… Read more »

ORNL study: The best use of natural gas for cars is production of electricity for EVs

What’s more efficient, using natural gas to power an ICE vehicle, or using it to generate electricity to power an EV? A well-to-wheels (WTW) analysis by a team of researchers at the Oak Ridge National Laboratory (ORNL) has found that, with a high PTW (pump-to-wheels) efficiency and the potential for high generation efficiency with NGCC… Read more »

ORNL researchers extend battery life with dual-function electrolyte

Researchers at the DOE’s Oak Ridge National Laboratory have developed a unique battery chemistry that promises to greatly extend battery life by making the electrolyte serve two functions. In a study, Pushing the Theoretical Limit of Li-CFx Batteries: A Tale of Bi-functional Electrolyte, which was published in the Journal of the American Chemical Society, ORNL… Read more »

EVs reach 90% market share in Norway as the overall auto market falters

The days of ICE vehicles in Norway are numbered. Some years ago, the government set a goal of 100% electric sales by 2025, and that goal is well within sight. In the month of February, plug-in vehicles took 92.1% of the market, up from 90.1% year-on-year. Battery EVs took a 90% share, as recent tax… Read more »

Researchers recommend isostatic pressing for solid-state battery manufacture

After months of encouraging test findings, Oak Ridge National Laboratory (ORNL) battery researchers are suggesting that the solid-state battery industry focuses on isostatic pressing to commercialize next-generation batteries. Isostatic pressing employs fluids and gasses like water, oil, or argon within a machine to exert consistent pressure throughout a battery component, generating a homogeneous material. This… Read more »

Public-private research project to develop US graphite supply for EVs

Ramaco Carbon, a carbon technology business, is working with Oak Ridge National Laboratory (ORNL) to create “made in America” large-scale graphite-making technologies from coal.  A fossil energy and carbon management program field work proposal supported by Ramaco Carbon and ORNL aims to take a bench-scale ORNL process to the commercial scale in two years. Ramaco… Read more »
