Elemental Tuning of NMC Cathode Materials: Atomic Structural Variations Drive Performance Improvements.
Review in Small (Weinheim an der Bergstrasse, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Layered lithium nickel-manganese-cobalt oxides (NMCs) have emerged as state-of-the-art cathode materials for lithium-ion batteries (LIBs) due to their high energy density and low cost. However, the underlying mechanism behind the performance decay that is associated with elemental compositions is not yet fully understood. This review aims to clarify the relationship between electrochemical performance and structural evolution by examining the role of individual elements in NMC materials. We investigated the impact of compositional variations on overall electrochemical property and provided a comparative analysis of single crystal (SC) and polycrystalline (PC) NMCs. The atomic-level interactions that connect structural characteristics and electrochemical properties were reviewed. We also discussed elemental variations in various modification strategies, including substitution, doping, concentration gradients, and surface coatings. The influence of primary and secondary particle sizes on battery performance was examined to guide the development of next-generation liquid and solid-state LIBs. The complex interplay between composition, morphology, and processing techniques provides valuable insights into designing a high capacity-retention cathode of Ni-rich and Co-free materials. Understanding the correlation between atomic structural variations is crucial in optimizing cathode material design to meet the increasing demands of high-energy-density and long-cycle-life batteries with both liquid and solid electrolytes.
