Surface charge density is the key factor for developing high performance triboelectric nanogenerators (TENG). The previously invented charge excitation TENG provides a most efficient way to achieve maximum charge output of a TENG device. Herein, criteria to quantitatively evaluate the contact efficiency and air breakdown model on charge excitation TENG are established to enhance and evaluate charge density. The theoretical results are further verified by systematic experiments. A high average charge density up to 2.38 mC m −2 is achieved using the 4 μm PEI film and homemade carbon/silicone gel electrode in ambient atmosphere with 5% relative humidity. This work also reveals the actual charge density (over 4.0 mC m −2) in a TENG electrode based on quantified surface micro-contact efficiency and provides a prospective technical approach to improve the charge density, which could push the output performance of TENG to a new horizon.

“…V b = f (p × d, d) has been illustrated in several researches. [6][7][8][9][10][11][12].This voltage is higher for cylindrical geometry than for plane one. [13] The breakdown voltages of gases are follow up Paschen's law in parallel-plate geometries, but it is not directly applicable in non-planar geometries, because of the confusion about the distance between the electrodes and distortion of the electric field.…”

The DC gas discharge is established between coaxial cylindrical stainless steel electrodes. The coaxial cylindrical DC discharge device consists of an outer grid cathode and inner rods anode with 4 mm gap between them. This experimental study is focused on the effect of gas pressure and electric field strength on breakdown voltage. There is a balance between the electron attachment and first ionization collision, so the Second Townsend emission is the responsible for maintain the discharge. The I-V characteristic curves for different pressures of hydrogen gas indicate that the highest current appears for the highest gas pressure. The gas breakdown voltage varies as a product of Pd and Townsend's coefficients depends on gas pressure and E/P, where E is the electric field and P is the gas pressure.

“…Such a deviation from the Paschen law can be attributed to the fact that the loss of charge particles due to diffusion toward the side walls of the discharge tube increases as the distance between the cathode and anode increases. A theoretical description of this effect is given in [20,21].…”

-The initiation and characteristics of a low-pressure glow discharge in air in large-diameter discharge tubes are studied. A deviation from the Paschen law is observed: the breakdown curves U dc ( pL ) shift toward the higher values of U dc and pL as the interelectrode distance L increases. It is shown that the normal regime of a glow discharge is accompanied by gas ionization in the anode sheath. This takes place only for pL values lying to the right of the inflection point in the breakdown curve. The cathode-sheath characteristics in the normal and abnormal regimes of an air discharge for a duralumin cathode are determined. The axial profiles of the ion density, electron temperature, and plasma potential, as well as the anode voltage drop, are measured at various air pressures. © 2000 MAIK "Nauka/Interperiodica".
