A little known chemical reaction helps extend battery life. Sol Jacobs, Tadiran Batteries As remote wireless devices become increasingly essential to the Industrial Internet of Things (IIoT), there is a growing need to understand the principles behind extended battery life. Many IIoT nodes require a battery-driven energy source. These off-grid low-power applications fall into two […]
