Hard carbon
Hard carbon is a non-graphitizable form of carbon, made by carbonizing biomass or resin at 1000–1600 °C, and is the dominant anode material for sodium-ion batteries.
Hard carbon anode
A hard carbon anode is a battery negative electrode made from hard carbon, a disordered amorphous carbon that cannot be converted into graphite even above 3000 °C, and the leading anode for sodium-ion batteries.
Hard carbon anodes for sodium-ion batteries
Hard carbon anodes for sodium-ion batteries are disordered carbon materials that store sodium through adsorption, intercalation, and pore filling, since graphite stores little sodium, making hard carbon the leading anode candidate.

Harmonic filter
A harmonic filter is electrical equipment that reduces harmonic distortion in power systems by diverting or canceling harmonic currents from nonlinear loads such as variable frequency drives, rectifiers, and arc furnaces.
Harmonic resonance
Harmonic resonance in power systems occurs when the system's natural frequency, set by inductance and capacitor banks, matches a harmonic source like a variable-frequency drive, amplifying harmonic voltages far above normal levels and damaging equipment.
Harmonic restraint
Harmonic restraint is a technique in transformer differential protection that uses the harmonic content of inrush current, especially the second harmonic, to prevent relay tripping.
Harmonics (electrical power)
Power system harmonics are voltage or current components at integer multiples of the 50 or 60 Hz fundamental, produced by non-linear loads and measured as total harmonic distortion (THD).
