The safe storage of electrical energy with high energy and power density is a challenge. Materials and process engineering aspects are in the foreground at Fraunhofer IFAM in order to develop solutions for electrical, chemical, and thermal energy storage systems. The focus is on Li-ion, solid-state, and metal/air batteries.
All centrifugal pumps add heat to the fluid being pumped. This is due to friction from the rotating impeller. On water, this is approximately 3 F for a magnetic drive. Long suction lengths and larger suction pipe diameters can cause extended prime times. Check with the pump manufacturer for estimated prime times by equivalent lift.
