Artificial counterparts of conical-shaped transmembrane protein channelsa re of interest in biomedical sciences for biomolecule detection and selective ion permeation based on ionic sizea nd/or charge differences.H owever,i ndustrialscale applications such as seawater desalination, separation of mono-from divalent cations,a nd treatment of highly-saline industrial waste effluents are still big challenges for such biomimetic channels.Asimple monomer seeding experimental approach is used to grow ionically conductive biomimetic charged nanocone pores at the surface of an acid-functionalized membrane.T hese readily scalable nanocone membranes enable ultra-fast cation permeation (Na + = 8.4 vs.M g 2+ = 1.4 )a nd high ion charge selectivity (Na + /Mg 2+ = 6 )c ompared to the commercial state-of-the-art permselective membrane (CSO,S elemion, Japan) owingt on egligible surface resistance and positively charged conical pore walls.

The electrochemical properties of Li1.2Ni0.13Co0.13Mn0.54O2 (LLO) are improved by LiPF6 coating and subsequent heating.
