from chemistry to pack
Every push toward faster charging runs into the same wall eventually: it isn’t the wire, the electrode particles, or even the reaction kinetics that gives out first. It’s the electrolyte itself struggling to move enough lithium salt to where it’s needed, fast enough. That transport bottleneck has a name: concentration polarization. It’s one of the … Read more
Some papers you read and think, “ok, more of the same.” Others make you question things you thought were already settled. This work by Dr. Dirk Uwe Sauer and his team is definitely in the second category. They took one of the biggest hidden villains in lithium ion batteries, lithium plating, and showed that it … Read more
AION Engineering INC What is the N/P Ratio? The N/P ratio refers to the ratio between the effective capacity of the anode (negative electrode, N) and the cathode (positive electrode, P). In simple terms, it compares how much lithium the anode can store versus how much the cathode can provide. For a safe and reliable … Read more
While individual battery cells can charge in under 15 minutes, EV battery packs take much longer to fully charge. There are a number of factors that influence that, including temperature spread across the pack. Key Factors Limiting Battery Cell Lifetime During Charging At the cell level, the fastest rate at which a battery cell can … Read more
