天赐材料发布“不可燃”5V电解液

Core Viewpoint - Tinci Materials focuses on the development, production, and sales of fine chemical new materials, particularly in lithium battery materials and special chemicals, aiming to create a low-carbon and beautiful life for humanity [1]. Group 1: Product Development - Tinci has developed a new 5V electrolyte that utilizes high safety solvents, which are non-flammable and less volatile, significantly enhancing safety even in high-temperature environments [2][3]. - The traditional electrolytes used in the 5V LNMO system face challenges such as rapid cycle decay and severe gas generation. Tinci's 5V electrolyte addresses these issues by suppressing high-temperature gas generation and protecting electrodes, thus promoting technological upgrades in electrolytes [5]. Group 2: Performance Improvement - Tinci's 5V electrolyte expands the voltage window, allowing the LNMO system to operate stably at high voltages, overcoming the oxidation and gas generation issues associated with conventional carbonate solvents above 4.5V [5]. - Compared to traditional high-voltage electrolytes, Tinci's 5V electrolyte improves cycle life by 600 weeks at room temperature and 300 weeks at high temperatures, significantly enhancing battery cycle stability and contributing to safer and longer-lasting new energy solutions [5]. Group 3: Stability and Safety - By optimizing the formulation of the 5V electrolyte, Tinci creates a stable protective film on the surfaces of the anode and cathode, effectively reducing the dissolution and deposition of manganese (Mn), which enhances cycle stability [6]. - Experimental data shows that the Mn content in the anode after cycling with Tinci's 5V electrolyte is reduced by approximately 45% compared to conventional high-voltage electrolytes, further validating the advantages of the 5V electrolyte in improving battery stability [6]. Group 4: Application Potential - The high safety and stability of Tinci's 5V electrolyte make it an ideal choice for applications in power batteries, energy storage systems, and low-altitude economies, supporting electric vehicles, efficient energy storage, and drones for longer range, higher efficiency, and safer experiences [8].
