Univ. of Maryland team develops tin-film on wood fiber anode for Na-ion batteries; targeting grid storage

Green Car Congress

A team at the University of Maryland has demonstrated that a material consisting of a thin tin (Sn) film deposited on a hierarchical conductive wood fiber substrate is an effective anode for a sodium-ion (Na-ion) battery, and addresses some of the limitations of other Na-ion anodes such as capacity fade due to pulverization.
