Prototype Microsoft system uses indoor light to wirelessly charge phones

Wireless charging pads may be more convenient than traditional wired smartphone chargers, but a team from Microsoft Research in China thinks that they're still not convenient enough.

Instead, they envision a system in which users just toss their phone onto a table, where it's automatically charged using a beam of light. They've already built a working prototype of the system, which is known as AutoCharge. Read More

New Li-ion anode achieves 70 percent charge in just two minutes

Researchers at the Nanyang Technological University (NTU) in Singapore have developed a new, proof-of-concept anode for lithium-ion batteries that can charge to 70 percent of its capacity in only two minutes and has a very long lifespan of ten thousands charge/discharge cycles. The advance could lead to the production of high-rate lithium-ion batteries, with interesting implications for personal electronics and, perhaps, even electric vehicles.Read More
