Camphene-Assisted Fabrication of Free-Standing Lithium-Ion Battery Electrode Composites

چکیده
Free-standing electrode (FSE) architectures hold the potential to dramatically increase gravimetric and volumetric energy density of LIBs by eliminating parasitic dead weight volume associated with traditional metal foil current collectors, however FSE fabrication methods suffer from insufficient mechanical stability, electrochemical performance, or industrial adoptability. Here, we demonstrate a scalable camphene-assisted method that allows simultaneous casting templating FSEs comprised common LIB materials performance superior foil-cast counterparts. These porous, lightweight, robust electrodes simultaneously enable enhanced rate improving mass ion transport within percolating conductive carbon pore network collectors for efficient stable Li + storage (> 1000 cycle in half-cells) at increased areal densities. Compared conventional counterparts, camphene-derived exhibit ~1.5x density, capability, improved capacity retention coin-cell configurations. A full cell free-standing anode cathode cycled over 250 cycles greater than 80% an 0.73 mAh/cm 2 . This active-material-agnostic holds tailor morphology flexible, current-collector-free optimize high power is applicable other technologies advanced manufacturing methods.

Lithium-iron-orthosilicate is one of the most promising cathode materials for Li-ion batteries due to its safety, environmental brightness and potentially low cost. In order to produce a low cost cathode material, Li2FeSiO4/C samples are synthesized via sol-gel (SG; one sample) and solid state (SS; two samples with different carbon content), starting from Fe (III) in the raw materials (lo...
