What May Be Coming in Apple Watch 2

With a second generation refresh of the Apple Watch expected out next year, 9to5mac.com says multiple sources are touting some features we will probably see on v. 2.0. Among those are a Face Time video camera built into the top bezel, and a new WiFi system for more iPhone independence. Insiders say you may be able to do most basic communication over WiFi without going through your iPhone. One thing not expected is more battery life. Apparently, Apple says most customers are happy with what the device now has. Did we mention they plan additional pricey premium models starting at over $1000?

On the subject of batteries, some researchers at Stanford have come up with a way to make lithium-ion batteries safer. As has been known, they can overheat and catch fire sometimes. Engadget.com reports the researchers have developed a chemical layer over the lithium anodes that prevents the finger like dendrites from growing out and shorting the battery. The barrier utilizes a mixture lithium nitrate and lithium polysulfide, for you chemistry nerds. A nice side effect is longer life. The treated batteries hold 99% efficiency for over 300 charges, compared with 150 cycles without. The breakthrough could lead to electric vehicles that could go days without a recharge.
