Figure 3. Screening for smaller dopant formation energy of TM-LFP. A: Formation energies of LFP and TM-LFP. The white and light-yellow areas correspond to the elements with endothermic and exothermic formation, respectively. B: Classification of formation energy of TM-LFP compared with LFP, where the darker the color, the larger the formation energy. LFP: LiFePO4; TM-LFP: Transition metal-doped LFP.
