Tiny batteries supply power and cool down the chips simultaneously!

“Redox flow batteries” are those tiny batteries which known for its twofold nature of delivering power to the chips and concurrently cool down the chips.

This cooling of chips takes place with the assistance of liquid electrolytes which are impelled to the battery from the exterior in a loop, and once this liquid electrolyte moves through these loops it starts storing an enormous amount of energy that supports our batteries to cool down.

These flow batteries have one more astonishing feature is that they are rapidly rechargeable. The researchers’ team at ETH Zurich and IBM are the responsible hands who found the trail to make these tiny redox flow batteries that could be installed in computer chip stacks.

The most vital portion of the research is demonstrating that electrolyte liquid has the ability to cool a chip and discharge ample volume of heat that battery generates as electrical energy.

There is a numerous type of flow batteries have been discovered such as:

• Redox type
• Hybrid type
• Membraneless type

The Redox flow batteries are a reversible battery in which electrochemical compound is liquefied in the electrolyte. Instead of solid state diffusion, they work on uncomplicated knowledge of heterogeneous electron transfer. They should be called as fuel cell instead of batteries.

Few examples of tiny redox flow batteries are:

• Vanadium redox flow battery
• Polysulfide redox flow battery
• Uranium redox flow battery

Obsolete batteries have a low specific energy and which makes them heavy and give the little specific power which makes them too costly. In comparison to these obsolete batteries, new batteries are just 1.5 mm thick and the output of the new tiny battery correspondingly reaches a record high of 1.4 watts per centimeter square. The size, aspect makes it practical to interweave the battery with chips, this makes shrinkage of the size of electronic device possible.

One of the famous doctoral students of Poulikakos group Julian Marschewski and its researchers’ team are the few behind, the earliest idea to build such a tiny flow battery to combine energy supply and cooling.

The researchers’ team established a wedge-shaped channel system with the assistance of 3D printing equipment, which delivers the system with electrolytes by means of very little pumping power.

It has the potential to generate electrodes that impulse liquid into the membrane in two thin and porous layers where ions can flow and produce power as effectively as possible.

The acquaintance of this tiny redox flow battery prerequisites to execute from the research stage to engineering stage as it has the potential to produce extra energy than it does now.

The tiny redox flow batteries have the benefit of flexible layout, long life and quick reaction time, with no harmful emission and low maintenance. In comparison to LI-ion, ARFBs, and RFBs which operate at high current and power densities. These qualities of tiny flow batteries make it an awesome option for large-scale energy storage.
