The discharge performance of thermal batteries with long-life is mainly limited by the decrease of working temperature, due to the continuous heat release during the work process. In this contribution, we firstly propose a slow heat-supply component (SHSC) with layer structure, composed of reducers (Li–Si), oxidizers (CuO) and “lithium” permeation membrane (LPM), to compensate the released heat in thermal batteries. The LPM is composed of electronic conductor (CeO₂) and high Li⁺ molten salt conductor (LiCl–LiBr–KBr), which can modify the permeation rate of “lithium” by changing the electric conductivity. The results confirm that thereaction rates between Li–Si and CuO can be adjusted by changing the weights or compositions of LPM, and the heat supply rate of SHSC can be regulated. By using SHSC, the inner temperature of thermal batteries can be maintained properly. Moreover, the discharge capacity of thermal batteries with long working life, can achieve 10% increase at least, with SHSC as the heat supplied component, which are measured and confirmed in the real thermal batteries.

由于工作过程中不断释放热量，长寿命热电池的放电性能主要受到工作温度降低的限制。在这个贡献中，我们首先提出了一种具有层状结构的缓慢供热组件 (SHSC)，由还原剂 (Li-Si)、氧化剂 (CuO) 和“锂”渗透膜 (LPM) 组成，以补偿热量释放的热量。电池。LPM 由电子导体 (CeO ₂ ) 和高 Li ⁺熔盐导体（LiCl-LiBr-KBr），它可以通过改变电导率来改变“锂”的渗透率。结果证实，通过改变 LPM 的重量或组成可以调节 Li-Si 和 CuO 之间的反应速率，并且可以调节 SHSC 的供热速率。通过使用SHSC，可以适当地保持热电池的内部温度。此外，长寿命热电池的放电容量，以SHSC为供热元件，至少可实现10%的提升，在实际热电池中进行了测量和确认。
