Improved cycle lives of LiMn2O4 cathodes in lithium ion batteries by an alginate biopolymer from seaweed

Abstract

We report an alginate, extracted from brown seaweed as a polymeric binder for spinel LiMn₂O₄. The exceptional Mn²⁺ capture of the alginate extracted from brown seaweed resolves the chronic issue of a promising lithium battery cathode, LiMn₂O₄, upholding the feasibility of its use for emerging large-scale applications including electric vehicles.
