Abstract: Now use chemical fuel generation method does not prevent heat waste, if scientists can recover power generation in these power generation processes, and can further improve energy conversion efficiency, reduce waste. A group of engineers team in Pennsita State University developed a "thermal recovery ammonia", "can recover and exhibit low-grade thermal energy. Low-level thermal energy refers to an unhappy thermal energy, such as the thermal energy of seawater, heat energy, thermal energy of industrial waste, etc.
. The Trab battery developed by the research team of Pennsita State University can recycle low-gradeheats that continue to appear, and use battery charging. Of course, there are still other methods to recycle waste heat, but the TRAB battery has achieved very good balance between efficiency and cost.
The tachurch compound battery can only use only 1,500% of the thermoelectric conversion efficiency. Although the battery based on DivaleneDiruthenium is much higher, the cost is too high and the source is scarce. According to the researchers of the State University, the new thermal recycling battery system used the electrode material of the battery system used a wide range of copper and ammonia, and the conversion efficiency reached 29%.
Using the low-grade thermal energy in the ammonia compound can be heated, copper ions in the vicinity of the electrodes in the TRAB battery have reacted, transport electron charging. According to the researchers, the power density of TRAB is about 60 watts / square meter, about 6-10 times of other liquid power conversion systems. Researchers are still committed to improving power density, and achieving prototype products that can be produced in the future to achieve commercial applications.
