“Small yes remote”: scientists have developed a flow battery that cools the chips
Flow-through redox batteries that use liquid electrolyte are commonly used in large installations to store energy. For example, scientists from Harvard have developed a battery capable of maintaining their performance over 10 years, so they are well suited for storing the energy produced by solar panels and wind turbines. However, creating a small power source is another level.
Scientists from IBM and the Swiss Higher Technical School of Zurich have created a tiny flowing battery that performs two functions at once: feeds electrical chips with energy and simultaneously cools them.

A team of scientists from IBM and Zurich High Technical School managed to find two liquids that can act as electrolyte and coolant at the same time. “For the first time, we managed to create such a small battery capable of feeding the chips and cooling them,” notes graduate student Julian Marschewski.
The new flowing battery consists of several layers and has a thickness of 1.5 mm. The two inner layers of the battery are the positive and negative electrodes, which have a porous structure. Between them there is a membrane.
Using the capabilities of 3D printing, a team of scientists has developed a wedge-shaped system of microchannels, through which electrolytes flow. Through the porous electrodes, the liquids pass into a special membrane layer where dissociation occurs. The system was able to produce 1.4 watts of power per square centimeter. 400 milliwatts are spent on the pump, and 1 watt is left to power the chip.
In this case, the battery, being in close proximity to the chip, will remove excess heat. Note, the chemical reaction also produces heat, but its level is so small that it does not interfere with the cooling of the chip. In the future, the developers are confident, flow-through batteries will help to significantly reduce the size of mobile devices by eliminating large (and potentially dangerous) lithium-ion batteries.
The researchers also believe that this achievement will allow humanity to create small and efficient chips for powerful computing systems, solar panels that will independently store stored energy, and monitoring devices that do not require external power sources to be connected.
