4 Product Performance the Advantages of Life Power ® P2 • Inherent safety • Long cycle-life • Long calendar life • Very high discharge power • Fast-charge option • Outstanding performance at low temperature why is LifePo 4 INHereNtLY SAfe? Unlike other cathode materials, Lithium Iron Phosphate exists in nature in both discharged and charged forms; consequently both minerals are stable. The oxygen in the phosphate is fixed to the phosphorus by strong covalent bonds. Other figure 1: LifePo (discharged condition) 4 called triphylite Life Power ® P2 • Cyclability • Deep discharge capability • Environmentally friendly • Significant cost advantage • Lower total system cost • Availability cathode materials, especially nickelate, tend to release oxygen when heated > 230°C, which could potentially lead to temperature run-away reactions. This temperature excursion is not a concern for batteries based on LFP. figure 2: fePo (charged condition) 4 called Heterosite
figure 3: SeM photograph of Life Power ® P2 Süd-Chemie Life Power ® P2 is manufactured using a proprietary wet process that produces LiFePO 4 with outstanding performance. The key contributor to its superior electrochemical characteristics is the presence of primary particles in a size between 100-300nm, that are formed in the precipitation process. An image of the material is shown in the Scanning Electron Micrograph in Figure 3 above.
