| POLYFLON PTFE Dispersion forms fibers and becomes extremely workable at very low compression shear forces. This property makes it ideal for use as a binding agent for electrode and separator materials. This example shows POLYFLON PTFE being used as the MnO2 binding agent in the anode of a Li-MnO2 battery. |
Effects |
| A positive electrode can be made without using a stainless steel carrier, and only a small quantity of PTFE (about 2%) needs to be used. Because of this, the amount of MnO2 in the anode can be increased compared to components with stainless steel carrier. This in turn allows the discharge amount to be increased for the same volumetric capacity (improved volumetric efficiency). This result can be used to make batteries more compact and thinner. |
Applications |
| Pb batteries, NiCd batteries, Li-fluorocarbon batteries |
| Improvement in volumetric efficiency |
