re: Lithium-ion Batteries Made Cheaper, Safer

NO RATINGS
This may be a great improvement. However, the article seems to have some inconsistencies. The statement "Consumer Reports recommends lithium batteries in high-drain devices such as cameras and alkaline batteries in low-drain devices such as remote controls" I think refers to disposable lithium batteries, not rechargeable Li-ion batteries. Also, the statement "Additionally, using the acrylic S020 made it possible for high capacity retention - more than 500 cycles" seems odd; 500 cycles would not scratch the surface in an automotive application. Perhaps this is a misprint?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
