Metal complexes of folic acid for lithium ion storage

As a natural abundant biomolecule, folic acid (FA) was explored for the first time as a material for lithium ion storage. Most impressively, after the cooperation of metal ions (Co2+, Ni2+ and Fe3+), the fabricated complexes presented an enhancement in capacity retention as well as a long cycling life. This work suggests an effective strategy to enhance the performance of organic electrode materials.
