🔋 New Review: Why Electrode Balancing (N/P Ratio) Matters More Than You Think in Li-ion Batteries

Let's dive into a deceptively simple but critical design parameter in lithium-ion batteries: the negative-to-positive (N/P) capacity ratio. (Great work from Karim Zaghib et al.)

Why does it matter?
✔️ It directly impacts energy density, cycle life, safety, and fast-charging capability
✔️ Too low → lithium plating, dendrites, accelerated degradation
✔️ Too high → unused anode mass, lower energy density, excess SEI growth
