[CNMO News] In recent years, the scale of the global electric vehicle industry has expanded rapidly, and the power batteries closely related to it have also received more and more attention. Many researchers have devoted themselves to this, hoping to develop new technologies to promote the development of the industry. On October 18, CNMO learned that the R&D team of Murakami Yoichi Murakami and Japan Chemical Pharmaceuticals, etc., developed a method to predict the performance of "thermal chemical batteries".

Device for measuring the voltage generated by the temperature difference between electrodes

Thermochemical battery is a battery that generates electricity by generating temperature difference through electrodes. It is understood that the industry's research on thermochemical batteries is increasing due to the ability to continuously convert heat into electrical energy without producing by-products or consuming materials. The method developed this time will help promote the development of methods to utilize waste heat emitted by factories and cars to obtain electricity, etc.

Thermochemical battery is a battery that generates a temperature difference by connecting two electrodes in the electrolyte to obtain electricity. It is reported that in the past, there have been "thermoelectric components" that convert heat into electricity, and thermochemical batteries have the characteristics of being able to efficiently obtain high voltages and operate at low temperatures below 200 degrees. It is worth noting that most of the waste heat of factories and automobile waste heat are below 200 degrees, which is easy to exert the characteristics of thermochemical batteries. Therefore, many research teams hope to link the two to improve the output and conversion efficiency of thermochemical batteries.

According to reports, the R&D team has figured out the mechanism that has not been clearly defined before, how the current and voltage performance of thermal chemical batteries are determined by the material. Not only that, these values ​​can also be predicted. In addition, Professor Murakami said that it is expected to use waste heat when cooling pure electric vehicle (EV) batteries and heat generated by the human body.
