| Abstract:In this study， the renewable and low-cost cellulose was used for preparing the ion-exchange membrane via a simple dissolution and generation process with bamboo dissolving pulp as raw material， where the resultant cellulose membrane with an ionic conductivity of 0.099 mS/cm. The results showed that the lower thickness of cellulose membrane achieved the high performance of salinity-gradient power generation. At 500 times salt-concentration difference， the cellulose membrane with a low thickness of 32 μm， showed the open circuit voltage of -119 mV， short circuit current of 132.4 μA and output power density of 16.33 mW/m2. |
