Experimental and simulation investigations of combustion and explosion properties of isopropyl nitrate at different concentrations

To reveal the explosion hazard properties and combustion mechanism of isopropyl nitrate (IPN), a 20 L spherical explosion device was used to conduct macroscopic explosion property tests, and ReaxFF MD simulations were employed to analyze the microscopic reaction mechanisms. The f...

Entropy-Engineered Fe–O–Ni Orbital Coupling Enables Durable Co-Free Ni-Rich Layered Cathodes

Abstract Cobalt-free Ni-rich layered cathodes are promising for high-energy-density lithium-ion batteries, but their practical implementation is hindered by coupled Li/Ni cation disorder, lattice oxygen instability, and interfacial degradation originating from the unstable Ni–O e...
