Hermetically-sealed alkaline battery |
摘要 |
Alkaline Ni/Cd round cells (button cells) which are able to withstand long-term overloading with a relatively high current (five-hour current) for a practically unlimited time and still deliver approximately their rated capacity on discharge with an equal current after 12 months. The button cells of the invention comprise a negative electrode tablet provided with an auxiliary electrode comprising activated carbon integrated in the nickel wire gauze basket and a positive electrode constituted of a material which contains 20 wt. % to 35 wt. % metallic nickel as the second largest component of the mixture after Ni(OH)2, while the otherwide common conductive graphite is absent.
