Lithium manganese spinels tend to aggregate upon annealing and do not allow for attaining high discharge rates when used as cathodes in lithium-ion batteries. To obtain spinel samples of lower aggregation and better highrate properties, precursors synthesized by means of a citric acid-aided route are suggested to be pyrolyzed in an inert atmosphere, instead of pyrolysis in air. The synthesis of nanosized Li[Li 0.033 Mn 1.967 ]O 4 is described, and its characteristics including X-ray diffraction, scanning electron microscopy, and porosity, as well as electrochemical test results are presented. The particle size of the materials obtained is smaller, the degree of aggregation is lower, and high-rate properties are better than for analogues pyrolyzed in air. In particular, sample Li||Li[Li 0.033 Mn 1.967 ]O 4 cells deliver *60 mAh g -1 at the current loads of 4,000 mA g -1

“…A site occupied by a lithium ion is separated from the four neighboring ions by voids at 16c, so three-dimensional (3-D) channels (8a-16c-8a-16c) provide a passage for potential migration of lithium ions in the crystal body. 7,8 In an insertion cathode, the 3-D passages provide a chance for high rate capability. 9 In addition, Kalantarian et al 10 concluded that the LiMn 2 O 4 crystal structure could be interpreted as that of an n-or p-type semiconductor during the delithiation or lithiation process, respectively, considering the density of states calculated by several density functional theory methods, suggesting that the structure could sustain high current rates.…”

Spinel LiMn2O4 (LMO)-based composites, due to their combination of low toxicity, abundant natural resources, and excellent electrochemical performance, are regarded as promising candidate cathode materials for lithium ion batteries. Current energy storage demands are not being met with existing materials, however, because of their defects, such as fast capacity fading, low rate capability, and low specific capacity in practical applications. Manganese dissolution during electrochemical processes bears the major responsibility for capacity loss, apart from the electrolyte factor. Low electrical conductivity, low ionic diffusion efficiency, and large structural variation have adverse effects on the electrochemical performance of materials. With respect to these drawbacks, significant progress has been made recently on optimizing the performance of LMO-based cathode materials. In this work, we review recent progress in 1 structural design, designing composites with graphene/carbon nanotubes, crystalline doping, and coatings for improving the electrochemical performance of these cathode materials.

For energy storage devices, high energy density, high power density, cycle stability, and safety are the development goals. Solid‐state lithium metal batteries, with both safety and high performance, have become a hot topic in recent research. Although each component of these batteries has been studied for decades, and their individual performance has been improved markedly, the performance of their combination is still far less than expected. Without the aid of a liquid electrolyte, the ion pathways within and between solid elements are tortuous or even disconnected, making the cathode development in solid‐state lithium metal batteries more challenging than for those in lithium‐ion batteries with liquid electrolytes. This review focuses on the ion pathways in the cathode for all‐solid‐state lithium batteries with different dimensions, covering their types, characteristics, and challenges. The design and modification methods of the ion pathways, including element doping, coating, composite pathways, and new functional structures, are also discussed.
