Super Efficient Diamond Batteries from Nuclear Waste

So far, we have been dumping our dangerous nuclear waste into oceans or deep inside the earth, hoping they will stay there. Now, there is a better way out. Scientists are now confident they can use nuclear waste as a source of energy to convert radioactive gas into diamonds of the artificial type, not as jewelry, but to be used as batteries. Scientists claim the diamonds can generate their own electrical current. As they are made of radioactive material with long half-life, the batteries could Read more [...]

Explosion and Damage Proof High Energy Density Batteries

We seem to spend a major part of our waking life charging batteries of our smartphones, laptops, watches, wearables, and more. Although most of our gadgets work at lightning speeds, one common frustrating weakness lingers on—the batteries. Of course, they have improved tremendously in the last fifty years, yet they have retained characteristics such as being toxic, expensive, bulky, finicky, and most maddeningly, short-lived. The quest for a super battery does not end with smartphones alone, rather Read more [...]

Monitoring Batteries Wirelessly

Lithium-ion batteries, when used to drive automobiles, can operate reliably over long periods, but require considerable care. That means not operating them to the extreme ends of their state of charge or SOC. With passage of time and usage, the capacity of a lithium ion cell changes, and therefore, each cell in the system has to be managed so that it remains within its constrained SOC. As vehicle operation requires generating as much as 1000 V or higher, tens or hundreds of cells are necessary, Read more [...]

Ohm Battery: A Battery That Refuses To Die

A dead battery in the car is a misfortune any driver would willingly avoid. When it is important to reach a destination, a car that does not start because its battery is dead gives a terrible feeling. Most people do not want to think about the car battery too much, preferring rather to have it just work every time they start the car. The smart battery from Ohm Laboratories, Silicon Valley, does just that and makes sure you do not have to replace your car battery almost ever. In spite of modern Read more [...]

How Safe Are the Batteries You Use?

There is occasional news about exploding smartphone batteries. As this is a safety related issue, the topic has generated a lot of interest. Several researchers, from the National Physical Laboratory, UK, the Imperial College, London, ESRF the European Synchrotron, and UCL, the University College, London have tried to find out the reasons and the mechanism behind batteries exploding. Their research reveals how damage to the internal structure of the batteries can spread to neighboring batteries. Now, Read more [...]

SOUNDBOKS: Batteries to Power the Next Speakers

Your next portable speakers may be able to violate county noise ordinances without the necessity of them being plugged into a vehicle power inverter, a portable generator or even a wall socket. This is what Soundboks is claiming, and their speakers will be battery-powered. Most portable speakers are limited in their size and their power output. Usually, if you want sizes and power capacity beyond those, it becomes necessary to power the speakers through AC adapters or wall plugs so they can output Read more [...]

What are Flexible Batteries?

We are accustomed to thinking of batteries as heavy and chunky implements capable of storing energy and powering electronic devices. For long, use-and-throw carbon-zinc batteries along with rechargeable Lead-acid and Nickel-Cadmium batteries dominated. With the advent of portable devices such as netbooks, ultrabooks, and other hand-held devices, the battery market exploded with various types, of which, the most popular was the Lithium-ion rechargeable battery. However, with electronic gadgets Read more [...]

Flexible Aluminum Battery for Smartphones

Would you be interested in a battery that takes only a second to charge up and is flexible enough to wrap around your smartphone? While manufacturers would be more interested in the flexibility feature, most users will welcome the quick charging time. At Stanford University, researchers claim to have developed such a battery from cheap, plentiful materials. It is flexible and charges up very fast as well. The new aluminum battery has a foil anode made of flexible aluminum, a cathode of graphite Read more [...]

Rechargeable Batteries from Packing Materials

Sweden was in the news recently for their extreme recycling capacity. Swedes recycle waste to the extent that they have to import garbage from other countries for use as landfills. Others countries struggling to recycle their garbage may be interested in generating rechargeable batteries from discarded packing materials that do not degrade when used as landfills. At Purdue University, researchers have found a new way to recycle discarded peanut-shaped packing materials. They are turning these Read more [...]
