This invention discloses an electrolyte, its preparation method, and its application. The electrolyte comprises the following components: a lithium salt, a gas-suppressing additive, a solvent, and a negative electrode film-forming additive; the gas-suppressing additive includes at least one of phenyl vinyl sulfone and a disilane compound containing an olefin group. This invention proposes an electrolyte for reducing gas production in lithium-ion batteries, using at least one of a disilane compound containing an olefin group and phenyl vinyl sulfone as additives in the electrolyte, resulting in an electrolyte that effectively suppresses gas production in the battery.

This utility model discloses a 40mm tear gas smoke-generating riot control round for riot guns, relating to the field of riot control ammunition technology. The utility model includes a projectile assembly with a launching component at its bottom, and the projectile assembly includes an upper projectile body. By employing a high-low pressure chamber staged pressurization structure, the high-pressure chamber first accumulates energy during propellant combustion, then releases it to the low-pressure chamber through a pressure relief hole, propelling the projectile assembly to embed in the rifling and fly at high speed, increasing the range to ≥200m, with a maximum of 400m. This solves the problems of insufficient chamber pressure and limited range caused by the single high-pressure chamber design in existing technologies, meeting the needs of long-range law enforcement. It uses CS instead of CN as the irritant; CS is chemically stable, non-carcinogenic after combustion, has low skin irritation, and degrades quickly, resulting in minimal environmental impact. This solves the problems of toxic residues and health hazards associated with CN irritants in existing technologies, improving the safety of weapon use.
