polymer battery - Opis:
- As a result of the electrophilic protonation of a carboxyl group of di electric polymethylmethacrylate (PMMA) with trifluoromethanesulfonic acid (CF3SO3H), a modified conducting polymer material was produced in the shape of a thin elastic lamina and a dense conductive gel, whose density was 1.26 g/cm3. These polymers conduct electricity, do not dissolve In either cold or warm water and are also resistant to weather conditions. Their conductivity in room temperature is 7.5ź10-3 Scm-1 and it greatly increases above 154 K. Activation energy Ea decreases with increasing temperature in the range 154 K - 300 K from 1.47 eV to 0.69 eV. The magnesiumpolymer (Mg-Poly) cell is constructed with magnesium as the anode and conductive PMMA as the cathode and both electrodes are electrically connected with a polymer gel electrolyte. The ratek voltage of this cell is 2.4 V.
