Lithium-Ion Batteries Based on Non-Stoichiometric LiMn_2O_4 / Poly(3,4-ethylenedioxythiophene)

摘要

LiMn_2O_4 spinel has been recognized as a suitable alternative cathode to LiCoO_2 in Li-ion batteries for its non-toxicity,abundance and low-cost for applications requiring large rechargeable batteries such as non-polluting electric transportation.However,the capacity fade throughout charge/discharge cycling,particularly in ethylene carbonate:dimethyl carbonate (EC:DMC)-LiPF_6 electrolyte,is the main drawback which limits its use in commercial lithium ion batteries with graphite as negative electrode [1-4].
