Researchers demonstrate high-capacity Mn-rich Li-ion cathodes; a design pathway away from cobalt and nickel

Green Car Congress

The work, reported in the journal Nature , shows a possible design approach for cathode materials that move away from the current reliance on nickel and cobalt—which are limited resources and are associated with safety problems. The new study shows how manganese can work within this concept. —Lee et al.

Why Facebook (Or Meta) Is Making Tactile Sensors for Robots

Cars That Think

Or, new-ish, at least—there's a ruggedized and ultra low-cost GelSight-style fingertip sensor, plus a nifty new kind of tactile sensing skin based on suspended magnetic particles and machine learning. The DIGIT touch sensor is based on the GelSight style of sensor, which was first conceptualized at MIT over a decade ago.
