“…The initial thermal decomposition D r a f t temperature is 360 °C, and the thermal decomposition peak temperature is higher than 400 °C. Compared from the existing high heat resistant explosive hexanitrostilbene (HNS), DAP-4 showed good stability and compatibility [16][17][18][19][20][21][22][23][24][25][26] .…”

In this work, we report the thermal kinetics, thermodynamics, and decomposition mechanism of AP-based molecular perovskite energetic materials and estimate their thermal safety performance. Typical AP-based molecular perovskite energetic materials, (H2dabco)[NH4(ClO4)3] (DAP-4), (H2pz)[NH4(ClO4)3](PAP-4), (H2mpz)[NH4(ClO4)3](PAP-M4), and (H2hpz)[NH4(ClO4)3] (PAP-H4), were synthesized and characterized. These were studied using differential scanning calorimetry (DSC). The results show that all of the obtained AP-based molecular perovskite energetic materials have higher thermal decomposition temperatures, and the peak temperatures are more than 360 °C. All follow random nucleation and growth models. Other thermodynamic parameters, such as the reaction enthalpy (ΔH), entropy change (ΔS), and Gibbs free energy (ΔG), show that they are generally thermodynamically stable. Moreover, their adiabatic induced temperatures were obtained; TD24 of DAP-4, PAP-4, PAP-M4, and PAP-H4 were 246.6, 201.2, 194.5, and 217.5 °C, respectively. This study offers an important and in-depth understanding of the thermal decomposition characteristics of AP-based molecular perovskite energetic materials and their potential applications.

“…Metal hydrides (MHs) are in focus due to their wide applications in energy science as hydrogen storage materials, − heat storage materials, − additives in energetic materials, − and electrode materials in batteries. In electrochemistry, it is an inviting anode material in lithium-ion batteries due to its weak polarization, high theoretical capacity, and suitable working potential. − It also plays a significant role in nickel–metal hydride batteries, acting as an active negative electrode material. , Recently, a large number of hydrogen-rich metal hydrides were synthesized or predicted under high pressure, like CaH 6 , LiH 8 , BeH 2 , Li 2 MgH 16 , YH 3 , PbH 8 , AsH 8 , LaH 10 , etc.…”

Metal hydrides have wide applications in energy science. A large pressure gradient propels the hydrogen atoms out. A piezovoltaic device, a pressure gradient-driven battery, can therefore be realized when the migrations of protons and electrons are separated by different conductors. Here we investigate the piezovoltaic performance of PdH x with various proton conductors as electrolytes and experimentally detect an output current of ≲40 nA and a voltage of ∼0.8 V for a 3 μg sample. We also demonstrate the escape of hydrogen atoms from a palladium lattice under an increasing pressure gradient using X-ray diffraction. The relationship between piezovoltaics (chemical process) and piezoelectricity (physical process) is like that between a chemical battery and a capacitor. Our work demonstrates the piezovoltaic application of metal hydrides and provides a new way to convert mechanical energy into electrical energy.
