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.

“…1,2 However, renewable energy is intermittent, and it needs to be balanced and integrated into the grid smoothly and safely. [10][11][12][13][14][15][16][17][18][19] Great efforts have been made in the design of SIBs with high efficiency. Electrochemical batteries can efficiently store and release electricity in chemicals, showing the most promising in stationary applications for EES.…”

COMMUNICATION This journal isBased on low cost and rich resources, sodium-ion batteries have been regarded as a promising candidate for the next generation energy storage batteries in large-scale energy application for renewable energy and smart grid. However, there are some critical drawbacks limiting its application, such as safety and stability problems. In this work, a stable symmetric sodium-ion battery based on bipolar active material O3-type Na 0.8 Ni 0.4 Ti 0.6 O 2 is developed. This bipolar material shows a typical O3-type layered structure, containing two electrochemically active transition metals with redox couples of Ni 4+ /Ni 2+ and Ti 4+ /Ti 3+ , respectively. This Na 0.8 Ni 0.4 Ti 0.6 O 2 -based symmetric cell exhibits a high voltage of 2.8 V, a reversible discharge capacity of 85 mAh g -1 , 75% capacity retention after 150 cycles and good rate capability. This full symmetric cell will greatly contribute to the development of room-temperature sodium-ion batteries towards safety, low cost, long life, and will stimulate further research on symmetric cells using the same active materials as both cathode and anode.

“…For cathode materials ,sodium-based transition metal oxides such as carbon modified NaCrO 4 [70] show good electrical property and can accelerate the reversible insertion/extraction of sodium ions and the facile complementary redox reactions of Cr 4+ /Cr 3 + couple. Na 1.25 V 3 O 8 nanowires as cathode [71] provides an increased electrode-electrolyte contact area, better strain accommodation, prevent self-aggregation and also shorten Na ion diffusion path.Sulfates have been considered as cathode candidates for SIBs Na 2 M (SO 4 )·4H 2 O (M = Mg, Fe, Co or Ni) and their dehydrated derivatives Na 2 M(SO 4 ) 2 (M = Co or Fe) show electrochemical activity at potential 3.33.4 V vs. Na/Na + [72,73]. For anode materials in SIBs, various carbon materials with different structures [74,75] and different morphologies (such as carbon nanowires and hollow carbon nanospheres) [76,77] have been investigated, normally delivering a reversible capacity of about 250-300 mAh/g at a voltage range from 0-3 V).…”
