Thermally regenerative ammonia batteries (TRABs) have shown great promise as a method to convert low-grade waste heat into electrical power, with power densities an order of magnitude higher than other approaches. However, previous TRABs based on copper electrodes suffered from unbalanced anode dissolution and cathode deposition rates during discharging cycles, limiting practical applications. To produce a TRAB with stable and reversible electrode reactions over many cycles, inert carbon electrodes were used with silver salts. In continuous flow tests, power production was stable over 100 discharging cycles, demonstrating excellent reversibility. Power densities were 23 W m⁻²-electrode area in batch tests, which was 64% higher than that produced in parallel tests using copper electrodes, and 30 W m⁻² (net energy density of 490 Wh m⁻³-anolyte) in continuous flow tests. While this battery requires the use a precious metal, an initial economic analysis of the system showed that the cost of the materials relative to energy production was $220 per MWh, which is competitive with energy production from other non-fossil fuel sources. A substantial reduction in costs could be obtained by developing less expensive anion exchange membranes.

蓄热式氨电池（TRAB）作为一种将低等级废热转换成电能的方法，显示出了巨大的希望，其功率密度比其他方法高出一个数量级。然而，先前的基于铜电极的TRAB在放电循环期间遭受不平衡的阳极溶解和阴极沉积速率，从而限制了实际应用。为了在多个循环中产生具有稳定且可逆的电极反应的TRAB，将惰性碳电极与银盐一起使用。在连续流量测试中，在100个放电循环中，功率产生是稳定的，证明了出色的可逆性。批量测试中的功率密度为23 W m ^-2电极面积，比使用铜电极的并行测试所产生的功率密度高64％，而功率密度为30 W m在连续流测试中为^-2（净能量密度为490 Wh m ^-3-阳极电解液）。尽管这种电池需要使用贵金属，但是对该系统的初步经济分析表明，与能源生产相关的材料成本为每兆瓦时220美元，这与其他非化石燃料来源的能源生产具有竞争力。通过开发较便宜的阴离子交换膜可以大大降低成本。
