Application

The purpose of 9,9-Dimethylfluorene is to provide an effective ambient-air-tolerant method for the prelithiation of negative electrodes before assembling lithium-ion batteries. This compound's redox potential is particularly advantageous for common negative electrodes, including high-capacity ones like silicon, due to its ability to process rapidly. It not only compensates for the initial loss of active lithium but also facilitates the pairing with high-capacity, lithium-free positive electrodes, such as those comprising sulfur, oxygen, or V2O5. This capability is crucial for configuring lithium-ion batteries that require a lithium source from the negative electrode to achieve high energy densities.
