CEES introduces a new vision for high-capacity hybrid Li-ion/Li-O2 batteriesSeptember 30, 2013

Researchers at the Center for Electrochemical Energy Science (CEES) at Argonne National Laboratory have presented a vision for designing hybrid Li-ion/Li-O2 cells that would provide an energy density significantly higher than that of conventional Li-ion cells, without the need for external oxygen.

Three Argonne projects win DOE funding to improve vehicle technologiesSeptember 12, 2013

Argonne has received $4.7 million from the DOE for three projects to develop new vehicle technologies, including capacitors, electrochemical couples and electrolytes for batteries intended for hybrid and electric vehicles.

Not Your Normal Power Box

The Ten Hundred and One Word Challenge invited the 46 Energy Frontier Research Centers (EFRCs) to represent their science in images, cartoons, photos, words and original paintings, but any descriptions or words could only use the 1000 most commonly used words in the English language, with the addition of one word important to each of the EFRCs and the mission of DOE: energy.

CEES entry wins DOE 1001 word challenge for "best science lesson"July 12, 2013

A team from CEES won the "Best Science Lesson" award in the U.S. Department of Energy's The Ten Hundred and One Word Challenge for Energy Frontier Research Centers.

A polymerizable additive for passivating high-voltage cathodesDecember 7, 2012

High-voltage cathode materials are being developed for lithium ion (Li-ion) batteries with the goal of significantly increasing battery energy density. Conventional Li-ion battery electrolyte systems are quite unstable at these high potentials, leading to short calendar and cycle lives, as well as potential safety issues. In this research project, we are studying the use of organic monomers as electrolyte additives that will oxidize and polymerize to form stable passivation films on the surface of high voltage cathode materials.

Improving and observing lithiation reactions September 21, 2012

In a quest to understand and improve the behavior of lithium-ion (Li-ion) batteries, CEES researchers are exploring the potential to develop new enabling materials with improved lithiation capacity and to observe these reactions in real-time as these reactions proceed.

In situ study of solid electrolyte interphase (SEI) formationJuly 27, 2012

The solid electrolyte interphase (SEI), which forms spontaneously at the electrode-electrolyte interface, plays a critical role in the performance and safety of Li-ion batteries, but little is known about its structure from in-situ observations. This research used a model system, epitaxial graphene on SiC, to provide a well-defined surface that is similar to graphite, the most commonly used anode in Li-ion batteries.

Ask a scientist: Battery life and careJuly 1, 2012

Argonne battery scientists answer the question, "Can I make my battery last longer by letting it run all the way out before recharging?"

Argonne flows into utility-scale battery researchJune 28, 2012

Scientists at Argonne have developed an all-organic non-aqueous lithium-ion redox flow battery that would help expand use of large-scale solar and wind energy on the nation's electrical grid.
