Lately, some well known scientists from the renowned companies IBM and ETH Zurich university have finally built a tiny "flow" battery cell that has two main benefits of supplying power to electronic chips and at the same time cooling them. The liquid battery produces enough energy to power electronic chips while dissipating much more heat than it generates. The result could be smaller, more efficient chips, solar cells that store their own energy or devices used for remote monitoring that don't require external power sources at all.


The "Redox flow" batteries that make use of liquid electrolytes are normally used on a large scale to store energy as the case may be. We may consider this instance, recently Harvard Researchers created one of this battery that can last over ten good years with a very little degradation of the cell, infact making it more ideal to store wind energy or  solar energy as the case may be.



However, Building these battery on a scale just tiny enough for electronic chips is another matter on the other hand. Well the team from IBM and ETH Zurich have managed to find two liquids that are suitable enough to serve both as flow-battery electrolytes and at the same time a cooling agents that can dissipate enough heat from electronic chips in the same circuit. They did quote saying "We are the first scientists in the world to build such a small flow battery so as to combine energy supply and cooling all at the same time" this was said by one of the team member by name Julian Marschewski.

So using 3D printing technology, the team did developed a wedge-shaped micro-channel system that easily supplies the system with electrolytes using a very little pumping power required. By having it the resulting electrodes press liquid into the membrane layer where the available ions can now flow, thus generating power. More also the result is a system that generates about 1.4 watts per square centimeter, with 1 more watt left over to power the battery after taking pumping into account. Moreover, it easily gets rid of a lot more heat than it makes, pulling off the neat trick of powering the electronic chip and at the same time cooling the electronic chip.



However the battery needs to generate more electricity than it does right now, so the main idea now needs to shift from the research into the engineering stages. However, the team thinks that it has a lot of potential for not just chips, but also lasers that require internal cooling, solar cells that store electricity directly in the battery cell and even large flow batteries optimized with liquid cooling channels.
