Impact of Graphene Oxide Lateral Size on the Long‐Term Stability of LiNi 0.5 Mn 1.5 O 4 Electrodes
Source abstract
Abstract
Increasing the operating voltage of Li‐ion batteries is crucial for enhancing the energy density. However, high‐voltage batteries suffer from long‐term stability issues. Graphene materials used as electrode additives have previously been shown to improve performance, yet the impact of variations in the graphene materials has not been thoroughly explored. Herein, we explore the effect of graphene oxide (GO) drop‐in additives with different lateral sizes in LiNi 0.5 Mn 1.5 O 4 (LNMO)‐positive electrodes. The additive reduces polarization of the LNMO electrode under long‐term cycling, leading to stability improvements, with the smaller lateral size proving to be superior.
