<正> It is discovered that the consistency of negative electrode is one of the main influences on battery performance, since the main raw material in negative electrode is metal hydride powder, ingredients, particle distribution and density of the powder could influence the pasting consistency in some aspects. With the study of MH powder characteristics, through the modification of the coating die, the consistency of negative electrode is improved efficiently.
