【Abstract】 AA size lithium-ion batteries, using Li₁.04Mn₂O₄/LiNi₀.94Co₀.06O₂ as cathode electrode and Mesophase Carbon Microballons （MCMB） as anode electrode, were investigated and tested. The results show that AA size lithium-ion batteries, using Li₁.04Mn₂O₄/LiNi₀.94Co₀.06O₂=1∶1 as cathode materials, synthesize advantages of high operating voltage of Li₁.04Mn₂O₄ and high specific capacity of LiNi₀.94Co₀.06O₂, overcome shortcomings of low specific capacity of Li₁.04Mn₂O₄ and low operating voltage of LiNi₀.94Co₀.06O₂. At ambient temperature, the batteries discharge capacity is 620 mAh and the specific energy are 120 Wh/kg and 290 Wh/L. After cycling 400 times, its discharge capacity is 86% of the initial capacity, and has excellent rate capability. When the battery of charged state is stored at 150 ℃ oven, it is not on fire and explosing.更多还原
