Silicon sponge improves lithium-ion battery performance
Date:7/10/2014

RICHLAND, Wash. The lithium-ion batteries that power our laptops and electric vehicles could store more energy and run longer on a single charge with the help of a sponge-like silicon material.

Researchers developed the porous material to replace the graphite traditionally used in one of the battery's electrodes, as silicon has more than 10 times the energy storage capacity of graphite. A paper describing the material's performance as a lithium-ion battery electrode was published today in Nature Communications.

"Silicon has long been sought as a way to improve the performance of lithium-ion batteries, but silicon swells so much when it is charged that it can break apart, making a silicon electrode inoperable," said Pacific Northwest National Laboratory Fellow Ji-Guang "Jason" Zhang. "The porous, sponge-like material we've developed gives silicon the room it needs to expand without breaking."

Room for improvement

Rechargeable lithium-ion batteries have two electrodes: one that's positively charged and made of lithium and another that's negative and typically consists of graphite. Electricity is generated when electrons flow through a wire that connects the two. To control the electrons, positively charged lithium atoms which scientists call ions - shuffle from one electrode to the other through another path: the electrolyte solution in which the electrodes sit.

The chemistry of lithium-ion batteries limits how much energy they can store. To increase the battery's energy capacity, researchers are looking at new materials such as silicon. A lithium-ion battery with a silicon electrode could last about 30 percent longer than one with a graphite electrode. Today's average electric vehicle could drive about 130 miles on a single charge if it used a lithium-ion battery with PNNL's silicon electrode.

Unfortunately, silicon expands as much as three times in size when it charges, creating pressure within
