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)
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".
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.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
