Thick film formation on Li-O₂ cathodes - breaking the true capacity barrier.

ABSTRACT: The theoretical energy density of Li-O₂ batteries is more than an order of magnitude larger than the current generation of Li-ion batteries. However, their practical performance is far less, in part due to their low true capacities, that is, capacity including the mass of the typically porous active material, electrolyte in the pores and the Li₂O₂ discharge product. This is further limited by the particulate nature of the product, yielding a theoretical maximum packing density of 74%, impacting both gravimetric and volumetric capacities. Here we introduce carbon nanochains (CNCs), a material synthesized from biomass that is structurally similar to a commonly studied cathode material, multiwalled carbon nanotubes (MWCNTs). CNCs form densely packed agglomerat
