Next-Generation Lithium-Ion Battery Designed, Should Hit Market Within 2-3 Years

Next-generation lithium-ion batteries that hold more than 3 times the charge that current batteries do and can recharge in around 10 minutes are now within reach. The new design, created by researchers at the University of Southern California (USC), may be commercially available within only 2-3 years according to those involved.

The design is based on replacing the currently used graphite anodes with porous silicon nanoparticles. This follows work done by the same researchers last year using silicon nanowires. The nanowire version actually lasts much longer (2000 recharge cycles) than the current nanoparticle version (200 recharge cycles) and conventional graphite-based designs (500 recharge cycles). But the researchers are confident that the lifespan of the nanoparticle design can be greatly improved in the near future. The problem with nanowires is just that they are relatively hard to mass manufacture, while silicon nanoparticles are readily available.
