The epsilon polymorph of LiMnO2 has low lithium-migration barriers but only one-dimensional pathways, while the spinel form has a three-dimensional network, even though both have the same fraction of favorable 0-TM sites.
Figure 6(c) further shows the sampled instantaneous Li posi- tions from the 2000 K AIMD trajectory

Local coordination and migration-network topology shape Li-ion transport and delithiation in the low-energy $\varepsilon$-LiMnO$_2$ polymorph
