Application

9,9-Dimethylfluorene (purified by sublimation) serves a crucial role in enhancing the efficiency of Li-ion batteries by enabling an ambient-air-tolerant method for negative electrode prelithiation before battery assembly. Its redox potential is well-suited for a wide range of high-capacity negative electrodes, such as silicon, allowing for rapid processing. This product addresses the initial active lithium loss and facilitates pairing with high-capacity lithium-free positive electrodes-like sulfur, oxygen, and V2O5-by providing a lithium source from the negative electrode. This capability ultimately helps create Li-ion batteries with significantly improved energy densities.
