# Proper handling helps make the most of Li-ion batteries

Li-ion batteries pack the most power per unit volume, but excessive charging or discharging can damage or destroy the battery and its surroundings, carefully designed circuits help you avoid such dire outcomes.

# Full-wave DC power supply

This is a simulation of a simple DC power supply based on a full-wave rectifier. This power supply uses center-tapped transformer and two diodes. This type of circuit is also known as a biphase rectifier.

# What is the perfect battery?

We often get puzzled by announcements of new batteries that are said to offer very high energy densities, deliver 1000 charge/discharge cycle and are paper-thin. Are they real? Perhaps - but not in one and the same battery.
