摘要
介绍了实施无汞扣式碱性锌锰电池的技术难度;指出了专利采用的是无汞电池技术,证据采用的是有汞电池技术,两者在结构上以及在负极集流层和负极材料方面有着显著的区别;指出了在锌膏中加入金属铟作缓蚀剂不是公知常识;分析了专利采用的技术具有明显的创造性。
The technical difficulty of mercury-free for alkaline Zn-MnO2 butt on cells was introduced. It was pointed out that the patent adopted mercury-fre e technology, while the evidence adopted mercury battery technology. The structu re, negative current collector and negative material of the mercury battery and mercury-free battery were diffetent. And adding indium to zinc paste wasn't gen eral knowledge . It was also pointed out that the patent had distinct creativity .
