Abstract

The reasons for the fall in the discharge capacity of the LiMn₂O₄ spinel composition with a Norit carbon filler in the redox reaction with lithium at a temperature of 271 K were analyzed using cyclic voltammetry and impedance spectroscopy. A comparison is made between the electrochemical behavior of LiMn₂O₄–Norit compositions, LiMn₂O₄ compositions with carbon nanotubes, and LiMn₂O₄ compositions with natural EUZ–M graphite to identify the key factors responsible for the efficient transformation of the composite electrodes under study in the prototype lithium battery.
