Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

This video explains how capacitors work and why they are essential in modern electronics. Capacitors store and release ...

While passive precharge employs a power resistor to create an RC circuit that charges the capacitor asymptotically, active precharge can employ a switching converter with a buck topology that uses ...

Taiyo Yuden to offer ‘lithium ion capacitors’ – devices that combine super-capacitor and lithium ion storage to create a component with twice the storage capacity of its own super-caps, a 3.8V ...

When compared to conventional disposable or rechargeable batteries, GoldCap capacitors offer a very rapid charging while delivering a high peak output current which makes them an interesting ...

It's "adsorb" not "absorb" (paragraph 2). Adsorption is a surface effect, whereas absorption implies one substance permeating the other. Grammar nit-pick aside, this sounds like a pretty cool tech.

9V batteries are often found in devices that aren’t used very often. If you use a NiCd rechargeable battery you may find it completely discharged by the time you need it. Capacitors on the other hand ...

A lithium polymer battery able to act as a super capacitor for rapid power delivery could be fielded within four years to enhance the performance of micro air vehicles. The mass and volume of power ...

Does your laptop battery die out right before you hit send on that important email? With scientists at MIT, Intel and other facilities researching microstructures (i.e. micro- or nano-scale pieces of ...

Individual pieces of graphene have some pretty amazing properties, but finding a way to produce bulk materials that make good use of those properties has been rather challenging. Now, researchers have ...
