A series of sodium alginate (SA)‐based binders are prepared for Li‐rich and Mn‐based oxides (LRMO) to address capacity loss and voltage fading issue. Our results demonstrate that the Ba2+ and Al3+ cations crosslinked SA binders can significantly enhance the electrochemical performance. A small volta...
