In a battery there is an accumulation of electrons on one terminal of the battery and an accumulation of positive ions on the other terminal. This will result in a(n) ...Select one:a.increase in battery deteriorationb.Potential differencec.decrease in battery currentd.Weak Batterye.None of these optionsClear my choice

The terminal voltage of a battery decreases with ______ while being charged. Increasing charging rate Increasing state of charge Increasing temperature All of the above

A) When a Li-ion battery is discharging, the electrode reactions are given as follows: (-) C6Li - xe = C6Li1-x + xLi+ (C6Li is Li-atom-intercalated, graphite-based composite) (+) Li1-xMO2 + xLi+ + xe = LiMO2 (M represents some kind of transitional metal) 1. ( ) During discharging, Li+ moves towards the negative electrode within the battery cell. 2. ( ) During charging, cathode reaction can be written as C6Li1-x + xLi+ + xe = C6Li. B) A MCFC is shown in the following figure, make judgements: 1. ( ) CH4 + H2O = CO + 3H2: one molar consumption of CH4 will cause transferring 12 mole electrons. 2. ( ) On electrode A, the reaction is H2 + 2OH- = 2H2O. 3. ( ) When the device is working, CO32- will move towards electrode B. 4. ( ) Reaction on electrode B is O2 + 2CO2 + 4e = 2CO32-

For an ion, the oxidation number is __.Multiple choice question.one less than the charge on the ionalways negativezerothe same as the charge on the ion
