Pyrolytic Carb<strong>on</strong> Deposit (PCD)<br />
Pyrolytic Carb<strong>on</strong> Deposit (PCD) symbiose with LiFePO4 is<br />
the key to material power, optimal energy <strong>and</strong> cyclability<br />
Pyrolysis of most organic<br />
materials during or after<br />
LiFePO4 synthesis leaves a<br />
c<strong>on</strong>ductive C deposit<br />
200 nm 100 nm<br />
Organic precursor can be<br />
solid, liquid or gas<br />
Carb<strong>on</strong> deposit is b<strong>on</strong>ded <strong>on</strong><br />
elementary particles or <strong>on</strong><br />
agglomerates = C-LiFePO4<br />
PCD c<strong>on</strong>trols sintering <strong>and</strong><br />
helps preserve Fe precursor<br />
or LiFePO4 size & shape, e.g.<br />
50 nm to 15 µ<br />
LiFePO4<br />
