A HIGH-TEMPERATURE COMPOSITE ADDITIVES FOR THE NICKEL HYDROGEN RECHARGEABLE BATTERY |
摘要 |
The present invention relates to a high-temperature composite additive for nickel-based batteries. Its technical purpose is to improve the conversion efficiency of trickle charging for batteries under high temperature. The weight-based components for the high-temperature composite additive for nickel-based batteries include 100 parts of nickel hydroxide and 0.1-10 parts of each one substance selected from any two groups/categories of elemental substances or compounds of rare-earth elements, elemental substances or compounds of IVB group elements or elemental substances or compounds of IVA group elements. Compared with prior art, the present invention leverages addition of high-temperature composite additive to substantially improve the conversion level of positive electrode activating substances under high temperature and improve oxygen evolution overpotentials. As a result, it can improve conversion efficiency of trickle charging under high temperature by 20-50% and accomplish normal operation for batteries under 80°C environment. This helps expand applications of batteries and in addition, manufacturing process for batteries is simple and battery structure is the same as general nickel-hydrogen batteries, making operation an easy job. |
