The Influence of NMC Composition on Li-ion Cell Performance

as Ni content of NMC chemistry increases the energy density of the battery cell increases

AION Engineering INC The performance of a lithium-ion cell is fundamentally governed by its material chemistry, particularly the composition of its cathode active material (CAM). In this article, we focus specifically on the role of nickel content in Nickel Manganese Cobalt Oxide (NMC) materials and how it correlates with energy density and power capability. Although … Read more

Interplay Between Electrolyte Mass, Capacity and C-Rate

electrolyte mass vs peak discharge c-rate

AION Engineering INC The 1.3 g/Ah Rule: A Starting Point When designing lithium-ion battery cells, a commonly referenced benchmark is the electrolyte mass-to-capacity ratio, typically around 1.3 g/Ah. This serves as a useful starting point for many applications, providing a baseline for ensuring sufficient ion transport within the cell. Why C-Rate Matters However, this ratio … Read more

The Importance of Electrode Density

AION Engineering INC The Relationship Between Electrode Density and Peak Discharge C-Rate In lithium-ion cell manufacturing, the calendering process is often not considered a critical step. However, it directly influences key performance parameters, such as capacity, C-rate capability, and cycle life. Therefore, calendering plays an important role in optimizing cell performance.
