Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

Fourier transform infrared (FTIR) spectra were obtained from spinel-type lithium manganese oxides of composition Li_xMn₂O₄ with 0 < x < 2.4, prepared by both chemical and electrochemical means. Each phase in this system has a distinct spectrum which is characteristic of the local (shortrange) structure. Mixtures of phases were analyzed using the method of scaled absorbance subtraction. The results correlate well with previously reported XRD and neutron diffraction analyses as well as with phase behavior indicated by electrochemical measurements. FTIR spectroscopy thus provides both qualitative and quantitative information and is shown to be an effective companion technique to X-ray diffraction.
