For complex heat capacity measurements, various types of temperature modulated differential scanning calorimetry (tm-DSC) can be used. However, three factors have influence on steady state of tm-DSC and hence cause errors in complex heat capacity mea

Open circuit voltage (OCV) was measured as a function of temperature and state of charge (SOC) for six kinds of lithium ion cells. The following cells were used: four kinds of commercial cell using a LiCoO2 cathode and a graphite or hard carbon anode

Heat generation behaviors during charge and discharge are examined by calorimetric measurement for several lithium-ion cells that are commercially available. Heat flow from the cell shows interesting variation reflecting the characteristics of the el

Modulation of heat flux DSC can be made by modulated light irradiation to the cells or the cell holders. For this type of temperature-modulated DSC, a theoretical approach has been tried to study steady state and hence its application to heat capacit

In order to characterize the reaction mechanism of lithium-ion cells during charge and discharge, two experimental methods, calorimetry and staircase voltage step coulometry (SVSC), are examined. As a result of calorimetry during charge and discharge

Mathematical analysis can be applied to elucidate dynamic steady state in temperature modulated DSC, because it is a linear process, and its results were reported previously, but it was done on assumption of constant heat capacity. In real measuremen

In order to characterize the heat generation behavior of a lithium-ion secondary battery during discharge, calorimetry of the battery was carried out. The temperature dependency of the heat generation was studied between 283 and 333 K. An exothermic

Computer simulations have been applied to elucidate the response of a sample to temperaturemodulated differential scanning calorimetry (tm-DSC) during transitions. Two cases have been simulated; a latent heat without supercooling (represented by an a

Dynamic differential scanning calorimetry (d-DSC) has attracted much attention, and it was postulated that high-precision heat capacity measurements can be made by this technique. However, its applicability, accuracy and precision have not yet been m
