As far as battery technology goes, Lithium Polymer cells are the bee’s knees ... Luckily, [Paul] sent in a great tutorial on building a LiPo charger that works over USB. The board [Paul ...

The circuit on this coin cell charger is built from an MCP73831, a nice single cell, lithium ion and lithium polymer charge management controller. In the standard, ‘I only need to read the first ...

Research demonstrates that the addition of certain dopants could improve a solid electrolyte’s interaction with a ...

Lithium-ion batteries have high energy density, so they hold more charge per volume but lose charge with aging even when not used. Li-Polymer has a lower energy density battery, but they are ...

The circuit has internal under/over-voltage ... current/constant voltage linear charger for single cell lithium-ion and lithium-polymer ... This USB/AC Li-Ion battery charger is targeted for portable ...
