ORNL scientists reveal battery behavior at the nanoscale
Date:9/14/2010

OAK RIDGE, Tenn., Sept. 14, 2010 -- As industries and consumers increasingly seek improved battery power sources, cutting-edge microscopy performed at the Department of Energy's Oak Ridge National Laboratory is providing an unprecedented perspective on how lithium-ion batteries function.

A research team led by ORNL's Nina Balke, Stephen Jesse and Sergei Kalinin has developed a new type of scanning probe microscopy called electrochemical strain microscopy (ESM) to examine the movement of lithium ions through a battery's cathode material. The research, "Nanoscale mapping of ion diffusion in a lithium-ion battery cathode" (Balke et al.), is published in Nature Nanotechnology.

"We can provide a detailed picture of ionic motion in nanometer volumes, which exceeds state-of-the-art electrochemical techniques by six to seven orders of magnitude," Kalinin said.

Researchers achieved the results by applying voltage with an ESM probe to the surface of the battery's layered cathode. By measuring the corresponding electrochemical strain, or volume change, the team was able to visualize how lithium ions flowed through the material. Conventional electrochemical techniques, which analyze electric current instead of strain, do not work on a nanoscale level because the electrochemical currents are too small to measure, Kalinin explained.

"These are the first measurements, to our knowledge, of lithium ion flow at this spatial resolution," Kalinin said.

Lithium-ion batteries, which power electronic devices from cell phones to electric cars, are valued for their low weight, high energy density and recharging ability. Researchers hope to extend the batteries' performance by lending engineers a finely tuned knowledge of battery components and dynamics.

"We want to understand from a nanoscale perspective what makes one battery work and one battery fail. This can be done by examining its functionality at the level of a si
