Development of graphene dispersions

Mitsubishi pencil’s battery graphene dispersion for conductive agents has proven results in charge/discharge cycle improvement.

Battery evaluation of graphene-based slurry

It was observed that, compared to AB slurry, adding a small amount of graphene in both low and high C-rate applications resulted in excellent charge/discharge performances.

Expected Battery Benefits

・Improves the conductivity of the entire electrode, resulting in faster charge and discharge rates and higher power output.
・Maintains structural integrity during charge and discharge cycles, reducing degradation and extending battery life.
・Increases the contact area for electrochemical reactions, providing more active sites for lithium-ion insertion and de-insertion, improving capacity and efficiency.
