A Cheaper Alternative for Batteries—Sodium Ion

A vast majority of electronic equipment running on batteries rely on the Lithium-ion technology for their electrode material. Since Lithium is relatively rare, its mining and refining make it an expensive material to use. This has led scientists to search for a cheaper alternative, and they have turned to the cheapest substance available, the common salt. A team from Stanford has developed a battery based on Sodium-ion whose cost per storage capacity is far lower than that of the existing batteries Read more [...]

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 [...]

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 [...]

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 [...]

Can capacitors act as a replacement for batteries?

It is common knowledge that capacitors store electrical energy. One could infer that this energy could be extracted and used in much the same way as a battery. Why can capacitors then not replace batteries? Conventional capacitors discharge rapidly, whereas batteries discharge slowly as required for most electrical loads. A new type of capacitors with capacitances of the order of 1 Farad or higher, called Supercapacitors: • Are capable of storing electrical energy, much like batteries • Can Read more [...]

What is a battery and how do they work?

Batteries power most of our mobile gadgets. These are small chemical powerhouses, which generate electricity by the chemical reaction within the battery housing. Although there are different types of batteries available, all batteries contain cells that have two electrodes and a chemical or an electrolyte between them. Various combinations of series and parallel connections of the electrodes make up a certain voltage rating for the battery. For ease of understanding, we will treat the battery Read more [...]
