UCR researchers develop novel sulfur-silicon cell architecture for Li-ion batteries

By mmillikin Researchers at the University of California, Riverside’s Bourns College of Engineering have developed a technique to create high performance lithium-ion batteries utilizing sulfur and silicon electrodes.

Reported in an open-access paper in the journal Scientific Reports, this sulfur-silicon full cell (SSFC) battery architecture gradually integrates controlled amounts of pure lithium into the system. The battery demonstrated a high specific energy density of 350 Wh/kg after 250 cycles at C/10.

Sulfur is an attractive cathode material due to its theoretical capacity of 1675 mAh/g. However, implementation of sulfur has been slow due to its inherent problems including polysulfide shuttling, volumetric expansion, and poor
