【Sodium Battery Electrolyte: Patent for Electrolyte Additives Used in Tianneng Lithium-ion Batteries】 Tianneng Battery Group Co., Ltd. applied for an invention patent named "Sodium-ion Battery Electrolyte Containing Sulfonate Ester-based Additives and Its Application" (Publication No. CN202410388456.3) in March 2024. This patent involves sodium-ion battery technology, specifically describing an electrolyte containing sulfonate ester-based additives and its application. By using this metal organic film-forming additive containing sulfonate ester, a dense and uniform solid electrolyte interface (SEI) film can be formed on the electrode surface, thereby achieving the effect of stabilizing the positive and negative electrode interfaces. In addition, the additive forms an electrostatic shielding layer under the action of manganese ions, effectively inhibiting the formation of sodium dendrites.
