Performance of a vertical thermally regenerative ammonia-based battery with a high-concentration ammonia chamber
摘要
Abstract
Thermally regenerative ammonia-based battery(TRAB)can effectively convert low-temperature thermal energy into electricity,but its serious ammonia crossover phenomenon seriously affects the power production stability of the battery.A vertical thermally regenerative ammonia-based battery with a high-concentration ammonia chamber(TRAB-C)was developed based on the phenomenon of ammonia crossover and stratification in this study.The construction of high-concentration ammonia chamber and the block layer of ammonia transfer was applied to adjust ammonia distribution and then alleviate ammonia crossover.At a higher ammonia concentration(≥6mol/L),TRAB-C obtained higher output power,higher total charge,and more stable power generation capacity than a TRAB with a conventional structure because it solved the ammonia crossover by regulating the distribution of ammonia concentration in the anode.In addition,the porous copper foam anode could block the downward transport of ammonia to alleviate ammonia crossover further.A porous electrode with appropriate pore density(80PPI)induced a large electrode surface area and favorable mass transfer inside the electrode,contributing to the maximum power(10.8mW)of TRAB-C.关键词
