Improving the Vanadium Redox Battery

Though considered a promising large-scale energy storage device, the vanadium redox battery's use has been limited by its inability to work well in a wide range of temperatures and its high cost. New research indicates that modifying the battery's electrolyte solution significantly improves its performance - so much so that the upgraded battery could improve the electric grid's reliability and help connect more wind turbines and solar panels to the grid.

Capacitive Sensor Signal Conditioner

ZMDI (Dresden, Germany) has expanded its family of capacitive sensor signal conditioners (SSCs) with the addition of the wide-dynamic-range ZSSC3122 cLite device. With new design technology, the chip delivers 14-bit resolution and 0.25% full-scale-output accuracy. A built-in sleep mode lowers current consumption to <1uA for temperatures up to 85°C, making the ZSSC3122 ideal in low-power battery applications, as well as industrial and rugged environments.
