Negative active material for zinc-air secondary battery and zinc-air secondary battery containing the same

摘要

The present invention relates to a negative electrode active material for a zinc air secondary battery and a zinc air secondary battery comprising the zinc negative electrode active material. The negative active material according to the present invention includes a lead compound and / or a sulfur compound together with a zinc compound as a main component, The amount of generated hydrogen gas is small and the corrosion resistance of zinc is improved to improve reversibility. Therefore, the zinc air secondary battery including the same has an advantage of excellent charge / discharge performance and service life.
