Scientists Invent 30 Year Continuous Power Laptop Battery

Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles […]

Batteries for Stationary, Grid Storage

Batteries for Stationary, Grid Storage

History of Stationary Batteries Stationary batteries were previously almost always lead acid. Size and weight is of lesser concern. The limited cycle count does not pose a major problem because the batteries are seldom deep discharged. Large stationary systems were mostly mature flooded systems that provide a reliable and economical service, but they needed regular […]
