Layered double hydroxides (LDH) are regarded as attractive pseudocapacitive materials due to their impressive capacitive qualities that may be adjustable morphological features. However, the layered structure of LDH renders them susceptible structural aggregation, which inhibits effective electrolyte transport and limits practical applicability after limited exposure active areas. Herein, we propose a simple template-free strategy synthesize hierarchical hollow sphere NiMn-LDH material with...
