Thermal Behaviour of the Li-Ion Cell

AION Engineering INC When selecting cells for a battery pack, one of the most critical considerations is the discharge C-rate. While datasheets provide discharge ratings, understanding the difference between continuous and peak discharge C-rates — and their thermal implications — is essential for safe and efficient battery design. What is Continuous Discharge C-Rate? The continuous … 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. The Importance of Calendering … Read more

Relationship Between DCIR and Peak Discharge C-Rate in Lithium-Ion Cells

Ohms law diagram

AION Engineering INC Correct management of performance parameters in lithium-ion cell technology plays a critical role in energy storage and fast discharge processes. DCIR represents the internal resistance of the cell under DC current. Therefore, how much the cell will heat up during discharge depends on the current drawn and the DCIR value. The heating … Read more

OIL RIG

How does a lithium ion battery work? And how does the mnemonic OIL RIG help us understand the processes? A battery consists of an anode (negative terminal) and a cathode (positive terminal). A polymer separator prevents direct contact, and a liquid electrolyte allows movement of ions between the layers. The anode and cathode are connected … Read more

Maximum Cell Discharge Capability

cell maximum current

Establishing the maximum cell discharge capability is difficult without understanding the design in detail. However, you can work towards establishing this limit with a number of measurements and calculations. The aim of this post is to describe that approach, the underlying physics, some of the measurements and calculations. First of all though we need to … Read more
