[ 79,85,86 ] In contrast to the general view that O3-structures are only synthesized in Na-rich environments, recent works have reported the discovery of Na-defi cient O3-type cathodes (i.e., Na 0.8 Ni 0.4 Ti 0.6 O 2 and Na 0.67 Fe 0.67 Mn 0.33 O 2 ) for NIBs, and such works could possibly broaden the strategy for O3 cathode development.…”

Grid‐scale energy storage systems (ESSs) that can connect to sustainable energy resources have received great attention in an effort to satisfy ever‐growing energy demands. Although recent advances in Li‐ion battery (LIB) technology have increased the energy density to a level applicable to grid‐scale ESSs, the high cost of Li and transition metals have led to a search for lower‐cost battery system alternatives. Based on the abundance and accessibility of Na and its similar electrochemistry to the well‐established LIB technology, Na‐ion batteries (NIBs) have attracted significant attention as an ideal candidate for grid‐scale ESSs. Since research on NIB chemistry resurged in 2010, various positive and negative electrode materials have been synthesized and evaluated for NIBs. Nonetheless, studies on NIB chemistry are still in their infancy compared with LIB technology, and further improvements are required in terms of energy, power density, and electrochemical stability for commercialization. Most recent progress on electrode materials for NIBs, including the discovery of new electrode materials and their Na storage mechanisms, is briefly reviewed. In addition, efforts to enhance the electrochemical properties of NIB electrode materials as well as the challenges and perspectives involving these materials are discussed.

“…For the positive electrode materials, Prussian blue analogues, polyanionic compounds and oxides are widely investigated. Among the numerous identified oxides of potential interest, Na 0.44 MnO 2 with a tunnel structure is particularly attractive because of its unique large tunnels suitable for sodium insertion/extraction [29][30][31][32][33][34] . The crystal structure of Na 0.44 MnO 2 is shown in Fig.…”

Ti-substituted tunnel-type Na0.44MnO2 oxide as a negative electrode for aqueous sodium-ion batteries

et al. 2015

The aqueous sodium-ion battery system is a safe and low-cost solution for large-scale energy storage, because of the abundance of sodium and inexpensive aqueous electrolytes. Although several positive electrode materials, for example, Na 0.44 MnO 2 , were proposed, few negative electrode materials, for example, activated carbon and NaTi 2 (PO 4 ) 3 , are available. Here we show that Ti-substituted Na 0.44 MnO 2 (Na 0.44 [Mn 1-x Ti x ]O 2 ) with tunnel structure can be used as a negative electrode material for aqueous sodium-ion batteries. This material exhibits superior cyclability even without the special treatment of oxygen removal from the aqueous solution. Atomic-scale characterizations based on spherical aberration-corrected electron microscopy and ab initio calculations are utilized to accurately identify the Ti substitution sites and sodium storage mechanism. Ti substitution tunes the charge ordering property and reaction pathway, significantly smoothing the discharge/charge profiles and lowering the storage voltage. Both the fundamental understanding and practical demonstrations suggest that Na 0.44 [Mn 1-x Ti x ]O 2 is a promising negative electrode material for aqueous sodium-ion batteries.

“…There is an urgent need for alternative energy storage devices with a performance comparable to, or better than rechargeable lithium batteries. One possible approach is to use sodium as an alternative charge carrier [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] to lithium, as the cost of sodium carbonate (Na 2 CO 3 ), for example, is only 3% of Li 2 CO 3 (ref. 5).…”

Rechargeable batteries using organic electrodes and sodium as a charge carrier can be highperformance, affordable energy storage devices due to the abundance of both sodium and organic materials. However, only few organic materials have been found to be active in sodium battery systems. Here we report a high-performance sodium-based energy storage device using a bipolar porous organic electrode constituted of aromatic rings in a porous-honeycomb structure. Unlike typical organic electrodes in sodium battery systems, the bipolar porous organic electrode has a high specific power of 10 kW kg À 1 , specific energy of 500 Wh kg À 1 , and over 7,000 cycle life retaining 80% of its initial capacity in half-cells. The use of bipolar porous organic electrode in a sodium-organic energy storage device would significantly enhance cost-effectiveness, and reduce the dependency on limited natural resources. The present findings suggest that bipolar porous organic electrode provides a new material platform for the development of a rechargeable energy storage technology.
