Addressing Bottlenecks to Achieve High‐Energy Sodium‐Ion Cells Using Tin Anodes
Advanced Energy Materials, EarlyView.The challenges in coupling high voltage cathode with Sn‐alloying anode or in anode‐free cell, using glyme based electrolytes to realize high energy Na‐ion cells are reported. Surface protection strategy such as SnO coating on Sn or trapping the parasitic species from poisoning the anode, helps improving the cyclability, with ∼100% capacity retention ...
