Abstract

An in-depth understanding of Na2Ti3O7 as a Na-ion battery anode is reported. The battery performance is enhanced by carbon coating, due to increased electronic conductivity and reduced solid electrolyte interphase formation. Ti(4+) reduction upon discharge is demonstrated using in situ XAS. The self...
