【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.

[Energy Storage: Chuneng signs four deals as 20 Chinese storage firms eye South America]

At Intersolar South America in Brazil (Aug 25-27), around 20 Chinese energy storage companies exhibited. Chuneng New Energy signed agreements with four partners, including MOUs with Argentina's Intermepro and Brazil's ION Energy and JSN Energia, plus a 1.5GWh cell framework deal with Windey Energy to supply cells for its first overseas storage plant in Bahia, Brazil. With a fragile grid, a 20.6% curtailment rate and the world's second-highest residential power prices, Brazil will launch Latin America's largest national storage tender (about 18GW in round one) in December 2026, drawing CATL, Trina, Hithium, CLOU, Gotion and Great Power to expand locally.
