Solid-state sodium batteries with P2-type Mn-based layered oxides by utilizing anionic redox

Abstract

Recently, P2-type manganese-based sodium layered cathodes have gained considerable attention as a viable option for grid-scale energy storage due to their high natural abundance, low cost, and high specific capacity...

Mitigating the Jahn–Teller distortion and phase transition in the P2-Na0.67Ni0.33Mn0.67O2 cathode through large Sr2+ ion substitution for improved performance

“…9–11 The quest for reliable cathode materials is of paramount importance in meeting the escalating demand for renewable energy systems. 12,13 Among various cathode compounds, layered oxides (Na x TMO 2 , 0 < x ≦ 1; TM stands for transition metals, especially nickel and manganese) exhibit desirable characteristics such as excellent conductivity and high capacity. 14–17 Moreover, the manufacturing techniques for oxide cathodes align well with those employed for commercial LIB cathodes, particularly LiNi 1/3 Mn 1/3 Co 1/3 O 2 .…”
