• Application: The purpose of 9,9-Dimethyl-9H-fluorene is to provide a method tolerant to ambient air for prelithiation of negative electrodes before assembling lithium-ion batteries. Its redox potential is particularly beneficial for the most commonly used negative electrodes, such as silicon, which have high capacities and require minimal processing time. This compound is instrumental in offsetting the initial loss of active lithium, facilitating compatibility with high-capacity, lithium-free positive electrodes, like sulfur, oxygen, or V2O5. By offering a lithium source from the negative electrode, it aids in configuring lithium-ion batteries with elevated energy densities.
