Lithium-ion batteries (LiBs) with Lithium titanate oxide Li4Ti5O12(LTO) negative electrodes are an alternative to graphite-based LiBs for high power applications. These cells offer a long lifetime, a wide operating temp. ••Degradation behaviour, SOH estimation and EOL prediction model of LTO b. Electrochemical energy storage devices are widely used for portable, transportation, and stationary applications. Among the different types of energy storage devices on the market, lithiu. 2.1. Investigated cellIn this research work, high-power LTO battery cells with a pouch format as shown in Fig. 1 have been tested and analysed for lifetime modellin. 3.1. Capacity fadeTo further investigate the capacity evolution over the lifetime, different stress factors were investigated, as explained in Table 2. For a better com. The objective of lifetime model development is to estimate the capacity loss of a cell in different applications and predict the expected lifetime as a function of time, or FEC.
