Modified peukert plot

FIGURE 19.4 Modified Peukert plot of the C-LiFeP04/C-Li4Tl50i2 18,650-type cell [170]. together with the cell temperature at various steps of this experiment. (For color version of this figure, the reader is referred to the online version of this book.)... 

Fig. 1.10 Modified Peukert plots of the Li//LiNii/3Mni/3 Coi 02 cells using solution 1 mol LiPFg in EC-DEC as electrolyte. Cells were cycled between 2.5 and 4.5 V vs. Li /LE. Cathode materials were synthesized by (a) the conventional wet-chemical method assisted by oxalic acid and (b) the two-step oxalate route. Reproduced with permission from [30].

Figure 12.15 displays the SEM images of two types of LFP particles LFP synthesized by solid-state reaction via the polymer-precursor method showing particles of 2-5 pm size and LFP synthesized by hydrothermal method showing particles with an average size of 300 nm. The modified Peukert plots are shown in Fig. 12.16. It is remarkable that the power-grade powders 75 % of the initial capacity at lOC-rate.
