Abstract
Today most of commercial Liion batteries LIBs are manufactured using toxic solvents and synthetic polymer binders In order to lower the cost and the environmental impact of LIBs an effort must be made to identify lowcost and environmentally friendly materials and processes In this work flexible selfstanding and easily recyclable LiFePO4 cathodes are obtained using cellulose fibers as biosourced binder and a quick aqueous filtration process easily upscalable capitalizing the wellestablished papermaking knowhow The obtained papercathodes show very good mechanical properties with Young’s modulus as high as 100 MPa discharge capacity values up to 110 mAh g−1 and very good cycling performances comparable with conventional polymerbonded LiFePO4 cathodes Moreover a complete papercell constituted by a papercathode a paperseparator and a paperanode is presented showing good cycling performances in terms of specific capacity efficiency and stability
