The lithium iron phosphate battery (LiFePO 4 battery) or LFP battery (lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate (LiFePO 4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode.
Lead cooled fast reactor scheme. The lead-cooled fast reactor is a nuclear reactor design that use molten lead or lead-bismuth eutectic coolant. These materials can be used as the primary coolant because they have low neutron absorption and relatively low melting points. Neutrons are slowed less by interaction with these heavy nuclei (thus not ...
Biplane. A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag ...
Advantages and disadvantages. Gray iron is a common engineering alloy because of its relatively low cost and good machinability, which results from the graphite ...
Labia stretching. Labia stretching, also referred to as labia elongation or labia pulling, is the act of lengthening the labia minora (the inner lips of the female genitals) through manual manipulation (pulling) or physical equipment (such as weights). [1] It is a familial cultural practice in parts of Eastern and Southern Africa, [2] and a ...
Self-constancy describes the ability to hold images of oneself and another person as both positive and negative at the same time. Another way it is defined is the capacity to accept the advantages and disadvantages of both the other and oneself; by either definition, maintained self-constancy is considered a byproduct of maturity.
In a soft-bearing machine, balancing is done at a frequency higher than the resonance frequency of the suspension. The suspension's displacement is dictated by the distance of the rotor's principal axis of inertia relative to the rotor's rotational axis defined by the rotor bearings. Both types of machines have various advantages and disadvantages.
An underground power line provides electrical power with underground cables. Compared to overhead power lines, underground lines have lower risk of starting a wildfire and reduce the risk of the electrical supply being interrupted by outages during high winds, thunderstorms or heavy snow or ice storms. An added benefit of undergrounding is the ...
