COLLEGE PARK, Md. – Researchers at the University of Maryland have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components. The structure is called a nanopore: a tiny hole in a ceramic sheet that holds electrolyte to carry […]

There’s another promising contender in the race to supplant the dominance of lithium-ion and metal-hydride based batteries in the world of energy storage. New research from the Karlsruhe Institute of Technology’s (KIT’s) Helmholtz Institute Ulm (HIU) details the development of an electrolyte that can be used in new magnesium-sulfur battery cells that would be more

In a serious case of out-of-the-box thinking, a design team at Roost in Sunnyvale California have come up with a method to add Wi-Fi connectivity to your old smoke or carbon monoxide alarm by just swapping batteries. Your smoke detector uses a 9 V PP3-type battery right? The new Roost battery contains 9 V lithium

It can be nice to know how much battery power you have. It becomes critically important with LiPo batteries since you can permanently damage them by running the voltage down too low. Typically battery voltage detection requires adding a circuit with extra parts and their associated power requirements. Wouldn’t it be great to be able to do this using

Recent advances of Li-Ion battery technology could be the kick start the faltering electric vehicle market needs for it to go main stream. As well as the fast charge time the new battery can be cycled more than 10,000 times and has a lifespan of 20 years. The work carried out at NTU Singapore replaces the

I needed a couple of AA batteries and found the display at the supermarket where they were all arrayed. Normally when I’m shopping in the supermarket, I tend to look at the price/kg or price/l when comparing similar products. In the case of the batteries, there was no such indicator. Fine, I thought, I’ll work

If you’ve ever wanted to power your Arduino or AVR from a battery for development testing (batteries have different power delivery qualities than, say, transformed AC or even a regulated wall wart in DC) testing but were tired of going through batteries (Hey, I admit I’ve sucked batteries dry in hours because of a slipped-up

Overview The Arduino Fio is a microcontroller board based on the ATmega328P (datasheet) runs at 3.3V and 8 MHz. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. It has connections for a Lithium
