Nanowire Batteries – Energizer Bunny for Gadgets

Stanford researchers recently invented a new type of rechargeable batteries employing silicon nanowire technology which can hold ten times more power than our current batteries.  With the ongoing boom in smartphone and tablet markets, nanowire batteries can easily turn out to be the next game changer in an ultra-mobile world. Need for nanowire batteries Most of our consumer electronics (including mobile phones and cameras) run on lithium ion batteries, which were first introduced by Sony Corporation Read more [...]

Ayushi believes in the possibly impossible and looks at a variety of theories that can make the impossible become possible. Her blogs reflect her belief - they describe what can make the impossible possible.


  1. Using silicon (Si) based anodes in lithium batteries are being researched for more than a decade. Several important challenges needs to be solved before we get can buy high energy density Si batteries in store.
    Silicon has a volume expansion of 300% during lithiation and de-lithiation. This will lead to collapse of the anode in the battery. Second problem will be solid electrolyte interface (SEI) layer formed on the silicon anode. Nano silicon can reduce these problems, and so will be adding a carbon material on silicon. But to what extent? It would be great if researchers find solutions to volume expansion and other current challenges, and we have batteries to last for several days in our laptops!!!

  2. Thanks for one’s marvelous posting! I seriously enjoyed reading
    it, you could be a great author. I will ensure that I bookmark
    your blog and will eventually come back later on. I want to encourage you to definitely continue your great posts, have a nice afternoon!
