Süd-Chemie <strong>Life</strong> Power ® <strong>P2</strong> is manufactured using<br />
a proprietary wet process that produces LiFePO 4<br />
with outstanding performance. The key contributor<br />
to its superior electrochemical characteristics is<br />
the presence of primary particles in a size between<br />
100-300nm, that are formed in the precipitation<br />
process. An image of the material is shown in the<br />
Scanning Electron Micrograph in Figure 3 above.<br />

<strong>Life</strong> Power ® <strong>P2</strong> demonstrates a specific capacity of<br />
almost 160mAh/g which is close to the theoretical<br />
maximum value of LiFePO 4 (Figure 4).<br />
In half cell measurements at a 10ºC rate,<br />
<strong>Life</strong> Power ® <strong>P2</strong> demonstrates a specific capacity<br />
