With the concentration cranked up, the battery was able to maintain its capacity for more charge cycles—hitting at least 150 cycles before dropping to 80 percent. Or to put it another way, it took about 200 cycles to drop to the equivalent capacity of a lithium-ion battery of that size. Another thing that helps is actually some simple clamping pressure, as this encourages the solid lithium to pack together better. All these numbers come from batteries placed in a small toggle clamp. Without that pressure, capacity drops significantly more quickly. … [Read more...] about Tesla research partnership progresses on new battery chemistry

The retro-tastic E-M10 Mark III is styled like a DSLR, with a viewfinder mounted on the top, but this camera is so small it scarcely takes up more space than mirrorless cameras with no viewfinder at all. It has a Micro Four Thirds sensor a little smaller than the APS-C sensors used by rival makers, and 16 megapixels rather than the usual 24, but the smaller sensor means smaller, faster-focusing lenses, and you’re not likely to notice the difference in megapixels in real-world shooting.
