U Texas team develops cobalt-free high-energy lithium-ion battery

Green Car Congress

Researchers from the Cockrell School of Engineering at The University of Texas at Austin have developed a cobalt-free high-energy lithium-ion battery, eliminating the cobalt and opening the door to reducing the costs of producing batteries while boosting performance in some ways. More nickel in a battery means it can store more energy.

UH, Toyota researchers develop new cathode and electrolyte for high-power Mg battery rivaling Li-ion

Green Car Congress

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. Magnesium ions hold twice the charge of lithium, while having a similar ionic radius. —Dong et al. Neither approach is practical.

Goodenough perspective on Li-ion batteries; in transportation, PHEVs for the near-term, longer term requires new electrochemical strategies

Green Car Congress

John Goodenough at the University of Texas at Austin and colleague Kyu-Sung Park have written a perspective paper on Li-ion batteries (LIBs), published in the Journal of the American Chemical Society. More recently, at the University of Texas, Austin, Dr. Goodenough patented a new class of iron phosphate materials.

Novel Li-metal electrode design could lead to more powerful solid-state batteries

Green Car Congress

The new electrode concept comes from the laboratory of Ju Li, the Battelle Energy Alliance Professor of Nuclear Science and Engineering and professor of materials science and engineering. —Ju Li. One of the biggest problems is that when the battery is charged up, atoms accumulate inside the lithium metal, causing it to expand.

Duke Energy upgrading Notrees 36 MW grid storage system with Samsung SDI Li-ion batteries

Green Car Congress

Duke Energy, Samsung SDI and Younicos are partnering to update Duke Energy’s 36-megawatt (MW) energy storage and power management system at the company’s Notrees Windpower Project in west Texas. Over the course of 2016, these batteries will be gradually replaced with lithium-ion technology.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The high energy storage has stimulated a worldwide study of Li-air batteries. Credit: ACS, Lu et al.

UT Dallas researchers use 2D MoS2 as protective layer for Li-metal anodes in Li-S batteries; extended cycle life

Green Car Congress

Researchers at The University of Texas at Dallas have used two-dimensional (2D) MoS 2 (molybdenum disulfide) as a protective layer for Li-metal anodes, greatly improving the performances of Li–S batteries. The deposition and dissolution process of a symmetric MoS 2 -coated Li-metal cell operates at a current density of 10?mA?cm
