Next Generation Lithium-ion Battery Design from USC Researchers

A new, cheap and strong lithium-ion battery design from USC Researchers that substitutes porous silicon nanoparticles for conventional graphite anodes can hold three times as much energy and charge in less than 10 minutes. With a commercial release timeline of two to three years will see it soon imposing a strong influence on the design of any products using lithium-iron batteries. The research, published in January’s Nano Research, details the replacement of conventional, plate-like design anodes with commercially available nanoparticle, silicon spheres etched with pores which allow silicon expansion and contraction without breaking. The increased surface area from the pores also allows lithium ions to diffuse in and out more quickly, improving performance.

A primary barrier for achieving commercial release is to improve the current 200 recharge cycles to 500 currently available with graphite designs.
