Opening Context
LMR cathode materials are evaluated not only by peak specific capacity, but also by whether the voltage profile, first-cycle efficiency, and electrode loading remain credible under realistic coin-cell screening conditions. For early R&D, a clean half-cell curve helps researchers separate material behavior from later full-cell balancing effects.
Why This Dataset Matters
The slide presents LMR cathodes in lithium metal 2320 coin cells tested at 0.1C/0.1C and 25 +/- 1 deg C. The combination of 6.0 mg/cm2 and 15 mg/cm2 loading, 2.0-4.8 V voltage range, and the stated electrolyte makes the dataset useful for lithium-rich cathode high-capacity evaluation. The key value is not only the headline capacity, but the way the voltage curve supports the interpretation.
Figure-Based Analysis
The figure below is the source dataset used for this article.
Figure 1. LMR charge-discharge performance dataset.
The reported specific capacity is 288.76 mAh/g and 298.36 mAh/g.
The reported first-cycle efficiency or coulombic efficiency is 90.61-91.86%.
The electrode loading is 6.0 mg/cm2 and 15 mg/cm2.
The voltage profile is technically consistent with the stated LMR cathode system. For this dataset, The broad high-voltage activation region and nearly 300 mAh/g discharge capacity fit the expected behavior of lithium-rich manganese-based cathodes. The Li metal counter electrode and carbonate-based electrolyte electrolyte frame the result as a focused material-screening dataset rather than a final full-cell performance claim.
System-Level Interpretation
From a cathode-engineering perspective, the dataset suggests that LMR can sustain a usable charge-discharge response under the stated loading and voltage limits. The curve shape also helps identify whether the material is behaving as expected: plateau-dominant systems should show clear voltage features, while layered oxides often show more sloped profiles as sodium or lithium content changes.
Application Outlook
Based on the shown data, the most realistic near-term use is next-generation high-energy cathode screening and formation-protocol development. Before making final cell-level claims, researchers would normally add repeat-cell statistics, rate capability, longer cycling, impedance growth, electrode density, and full-cell balancing data. Even so, the present curve provides a practical starting point for material selection and electrode-sheet development.
From Materials to Cells
Moving from a single half-cell curve to a working battery requires more than active material capacity. Slurry design, coating uniformity, calendaring density, electrolyte compatibility, separator choice, and pouch-cell format all affect how the same material behaves in a realistic device. That is why material screening, customized electrode sheets, and small-format cell testing should be treated as connected steps in one development workflow.
