Without compromising its other performances(such as low rate discharge performance,storage and safety) and with the consideration of the actual production running,the high-rate discharge of Zn-MnO2 alkaline battery was produced with methods such as using thinner separator,increasing the amounts of electrolyte absorbed via vacuum-absorption technique and optimizing the cathode or anode formula and so on.Through testing these batteries on high-rate discharge instrument and electric appliances subsequently,the obtained results were that the high-rate discharge performance of the batteries produced with these methods has been improved and met the demands from the customers.

采用Hummers法,在浓硫酸、高锰酸钾等氧化剂存在条件下,将石墨粉氧化制备成氧化石墨烯,将氧化石墨溶解于水中,然后用水合肼还原氧化石墨烯后制备得到石墨烯,同时,采用红外光谱、紫外光谱、透射电镜等手段对得到的氧化石墨烯和石墨烯进行了表征.结果表明:制备得到了氧化石墨烯和石墨烯,且二者已经充分剥离.
