Anode performance of pyrolyzed bacterial cellulose in secondary lithium-ion batteries and the effect of added metal phthalocyanines

Electrochemical properties of pyrolyzed bacterial cellulose and the effect of the addition of metal phthalocyanines have been investigated for application of the cellulose to electrodes of lithium-ion batteries. The electrodes made of pyrolyzed bacterial cellulose exhibit good stability and relatively high Coulombic efficiency in charge-discharge cycles. Furthermore, the addition of metal phthalocyanines before pyrolysis remarkably increases the charge-discharge capacities of the pyrolyzed bacterial cellulose. We propose the new application of bacterial cellulose as an electrode active material in rechargeable batteries.
