Batteries can be connected in series, parallel, or a combination of both, in order to give different power characteristics to ...

For those willing to put some elbow grease into it, there is an almost unlimited supply of 18650 lithium ion batteries around for cheap (or free) just waiting to be put into a battery pack of some ...

I have a main circuit board in a machine that over a year or two eventually drains a 3.6v lithium AA size down to 1.4V. This battery has a wire soldered at each end which is then soldered to two ...

LTO anodes face off against cheaper but shorter-lived graphite anodes ...

Basics of battery-charging systems. Regulating a charging MOSFET. Partitioning of the fuel gauge. Implementation of a battery-management system. 1. The battery fuel gauge can be implemented on the ...

New research shows that the next generation of lithium-sulphur (Li||S) batteries may be capable of being charged in less than five minutes, instead of several hours as is currently the case. New ...

IXYS Corp announced a range of Solar Cell PV-Arrays (“Solar Arrays”), and PV-Cards (“Solar Cards”), for charging various battery powered and handheld products such as mobile phones, PDAs, cameras, ...

Engineers report progress toward lithium-metal batteries that charge fast -- as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown -- quickly and ...
