摘要

The thermal profile of LiMn₂O₄ and LiAl _0.17Mn_1.83O_3.97A_0.03 was measured in an isothermal micro-calorimeter. The heat contributions are discussed in terms of reversible and irreversible heat generation. The endothermic and exothermic heat profiles observed during the charge and discharge processes are related to the Li insertion/extraction reaction in the spinel host structure for both materials. The reversible heat generation during cycling is estimated on the basis of the cell entropy change. The heat generation calculated from ΔS and the open circuit potential results shows good agreements with the experimental results obtained from the IMC at a slow charge/discharge rate. The contribution of irreversible heat generation on the overall heat generation rate is discussed.
