A beneficial combination of formic acid as a processing additive and fluoroethylene carbonate as an electrolyte additive for Li4Ti5O12 lithium-ion anodes

Formic acid is an efficient processing additive for Li 4 Ti 5 O 12 anodes, but the amount has to be carefully optimized. Fluoroethylene carbonate as electrolyte additive can further enhance the performance by facilitating the interfacial charge transfer.
