USC Researchers Invent Longer-Lasting Lithium-Ion Battery
2/25/2013

Researchers at the University of Southern California, led by Professor Chongwu Zhou, replaced graphite with porous silicon nanoparticles in anodes of lithium-ion batteries to come up with a new design. The battery, which could be available in two to three years, has a longer life and charges more quickly than lithium-ion batteries used now.   (Source: Mingyuan Ge & Chongwu Zhou/USC)

Re: Longer Lasting?

Awile, you're right, that's rather contradictory.

However, I think the "longer-lasting" statement refers to the fact that the new battery lasts longer on a single charge than a regular LI-Ion battery.

Longer Lasting?

I'm confused.  Although the title says that a longer-lasting battery was invented, the story says "Another weakness in the design is that the battery's lifespan isn't as long as traditional graphite-based design".

In what sense is the new battery longer-lasting?

Innovation is happening

There is a lot of innovation happening in the battery space at the moment and, in my opinion, it couldn't come at a better time. If you think about it, while so much other technology has evolved in leaps and bounds, batteries historically have been very slow to evolve yet we are still quite dependent on them to power all of our gadgets and devices. The idea of a longer-lasting battery that can recharge so quickly is a welcome innovation in this space.
