The development of lithium-ion (Li-ion) battery technology to meet the demanding storage and delivery requirements of energy, industrial, and automotive systems has spurred demand for safer, higher ...

Because stationary batteries and 48VDC power systems serve as lifelines for telecommunication networks, the reliability of these systems is of the utmost importance. Many system designers rely on ...

I will be talking about single-series (1sXp) cell configurations, for a simple reason – multiple-series configurations are not something I consider myself as having worked extensively with. The single ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...

Researchers at the Max Planck Institute for Sustainable Materials have uncovered how lithium dendrites ...
