Lithium-ion (Li-ion) batteries are comprised of cells that employ lithium intercalation compounds as the positive and negative materials. As a battery is cycled, lithium ions (Li+) exchange between the positive and negative electrodes. They are also referred to as rockingchair batteries as the lithium ions “rock” back and forth between the positive and negative electrodes [...]
We can see laptops every where, they’re becoming more and more popular as they are light, portable and personal to each of us. It is like they are nondetachable part of our daily life. But behind every Laptop is lying the power source which runs everything from CPU to DVD Rom, laptop battery at the [...]
Different Lead-Acid batteries and their application as they play an important role in the world of batteries!
The lead-acid battery has been a successful article of commerce for over a century. Its production and use continue to grow because of new applications for battery power in energy storage, emergency power, and electric and hybrid vehicles (including off-road vehicles) and because of the increased number of vehicles for which it provides the energy [...]
Electrochemical cells and batteries are identified as primary (non-rechargeable) or secondary (rechargeable), depending on their capability of being electrically recharged. Within this classification, other classifications are used to identify particular structures or designs. Primary Cells or Batteries These batteries are not capable of being easily or effectively recharged electrically and, hence, are discharged once and [...]
A battery is a device that converts the chemical energy contained in its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction. In the case of a rechargeable system, the battery is recharged by a reversal of the process. This type of reaction involves the transfer of electrons from one [...]
A cell is the basic electrochemical unit providing a source of electrical energy by direct conversion of chemical energy. The cell consists of an assembly of electrodes, separators, electrolyte, container and terminals. A battery consists of one or more electrochemical cells, electrically connected in an appropriate series/parallel arrangement to provide the required operating voltage and [...]
You are going to buy a new battery for your power tool? That’s all you know so far since your power tool isn’t working properly and you guess you would need a new battery. But it’s hard to read the battery label and specification, In fact, some would even say that power tool batteries essentially [...]
Microsoft has certainly had some ups and downs with its products over the years, but we’re pretty sure the company’s new “InstaLoad” technology falls somewhere between a home run and the best thing it’s ever done. It promises to do nothing short of redefine the way you insert batteries, and let you shove them into devices without [...]
