With China's robust development of wind and solar power generation, energy storage has become paramount [1, 2], leading to heightened efforts in constructing pumped storage power stations and increasing the utilization of pumped storage units. Pump-turbine are advancing towards higher and ultra-high...
Mechanical abuse can lead to internal short circuits and thermal runaway in lithium-ion batteries, causing severe harm. Therefore, this paper systematically investigates the thermal runaway behavior and safety assessment of lithium iron phosphate (LFP) b
