氢氧化镍被氧化的电位是多少啊？

RT 我在研究催化反应。 请问大家是否知道存在一种氧化剂（吸电子能力比较强），但是却不能将 氢氧化镍（NI(OH)2) 氧化成 羟基氧化镍(NIOOH) 的啊？ 顺便告诉我下，氢氧化镍氧化成羟基氧化镍的电位（能量）是多少啊？ 谢谢！急需啊~~~~ 我是新手，有些术语不准确，望指正，谢谢！  |

其实我对这个问题也比较关心. A rechargeable battery, also known as a storage battery, is a group of two or more secondary cells. These batteries can be restored to full charge by the application of electrical energy. In other words, they are electrochemical cells in which the electrochemical reaction that releases energy is readily reversible. Rechargeable electrochemical cells are therefore a type of accumulator. They come in many different designs using different chemicals. Commonly used secondary cell chemistries are lead and sulfuric acid, nickel cadmium (NiCd), nickel metal hydride (NiMH), lithium ion (Li-ion), and lithium ion polymer (Li-ion polymer). Rechargeable batteries can offer economic and environmental benefits when used instead of one-time-use disposable batteries. Most rechargeable battery technology has been adapted into the standard “AA,” “AAA,” “C,” “sub-C,” “D,” and “9-volt” configurations that consumers are familiar with. While the rechargeable versions of these types of cells have a higher up-front cost than disposable batteries, rechargeable batteries can be discharged and recharged many times. Similarly, while the metals and chemicals in rechargeable cells can be more toxic than those in disposeable batteries, disposeable batteries nevertheless do release toxins into landfills and other more sensitive parts of the environment. Some manufacturers of NiMH type rechargeable batteries claim a lifespan up to 3000 charge cycles for their batteries.
