Cheap, strong lithium-ion battery developed at USC

the nanowires. The particles function similarly and can be made in any quantity desired.

Though the silicon nanoparticle batteries currently last for just 200 recharge cycles (compared to an average of 500 for graphite-based designs), the team's older silicon nanowire-based design lasted for up to 2,000 cycles, which was reported in Nano Lett last April. Further development of the nanoparticle design should boost the battery's lifespan, Zhou said.

"The easy method we use may generate real impact on battery applications in the near future," Zhou said.

Future research by the group will focus finding a new cathode material with a high capacity that will pair well with the porous silicon nanowires and/or porous silicon nanoparticles to create a completely redesigned battery.
