Electroshock weapon technology uses a temporary high-voltage, low- electrical discharge to override the body's muscle-triggering mechanisms. Commonly referred to as a stun gun, electroshock weapons are a relative of , which have been around for over 100 years and are the precursor of stun guns. The recipient is immobilized via two metal probes connected via wires to the electroshock device. The recipient feels , and can be momentarily paralyze.

Which electrode materials are used for supercapacitors?
Carbon materials are the most commonly used electrode materials for supercapacitors and the researches of carbon materials are significant for developing supercapacitors. Herein, this article presents the energy storage mechanisms of supercapacitors and the commonly used carbon electrode materials.
Can carbon fiber electrode materials be used for supercapacitors?
At present, research on carbon fiber electrode materials for supercapacitors is very active. Carbon fibers can be activated by concentrated HNO 3 and KOH to enhance their specific surface area and surface wettability, thereby enhancing their electrochemical energy storage performance [8, 9].
Can OLC be used as electrode materials for supercapacitors?
As a type of carbon materials, OLCs can be used as electrode materials for supercapacitors. Table 1 summarized the electrochemical performance of different carbon materials. The exohedral structure of OLC with non-porous inside the particles allows electrolyte ions to enter the material easily .
Can porous carbons be used as supercapacitor electrodes?
Application of Porous Carbons as Supercapacitor Electrodes Some methods for synthesis of porous carbons have been described previously, and porous carbons will obtain further applications. This is because one of the ultimate goals of supercapacitor research is to achieve high charge-storage capacity at ultra-high scan rates or current densities.
