Jeff Dahn—How to Extend the Service Life of EV Batteries? 2025

March 14, 2026

Jeff Dahn—How to Extend the Service Life of EV Batteries?   Key Insights from Jeff Dahn (Dalhousie University): Maximizing the Service Life of NMC/Graphite EV Batteries In a recent webinar, Professor Jeff Dahn shared critical methodologies for maximizing the lifespan of NMC/Graphite (NMC/Gr.) battery systems. He emphasized that High State of Charge (SoC) and Elevated Temperatures are the primary catalysts for battery degradation. This is largely due to the accelerated parasitic reactions between the cathode and electrolyte at high SoC, coupled with the increased kinetics of side reactions under high-thermal stress. Furthermore, Dahn highlighted the impact of Depth of Discharge (DoD). A larger DoD during cycling leads to more severe

Tesla Chief Scientist Jeff Dahn: How NMC Batteries Maintain 80% Capacity Retention After 8 Years of Cycling? Source: “Battery Class” (Official WeChat Account) Lithium-ion batteries serve as the core components for Electric Vehicles (EVs) and Grid-scale Storage Systems, where their cycle life directly dictates the Total Cost of Ownership (TCO). While the industry generally perceives high-nickel cathode materials, such as NMC, as having inferior cycling stability, recent breakthroughs from Jeff Dahn’s research group at Dalhousie University have challenged this conventional wisdom. The study conducted a systematic decoupling analysis on NMC/Graphite pouch cells with cycling durations ranging from 3 to 8.2 years. The results revealed that optimized Single-Crystal NMC532/Artificial Graphite cells

This advancement goes beyond mere incremental parameter gains; more importantly, through innovative material science, it simultaneously addresses core industry pain points—charging speed, cruising range, and low-temperature performance—effectively narrowing the user experience gap between Battery Electric Vehicles (BEVs) and traditional Internal Combustion Engine (ICE) vehicles.   BYD Second-Generation Blade Battery: 8 Core Technical Highlights 1. Charging Performance (C-rate Capabilities) Expert Translation: Ultra-fast charging: 10% to 97% SOC (State of Charge) in just 9 minutes (10% to 70% in 5 minutes). Even

Electrochemical Reversibility

How to determine electrochemical reversibility from cyclic voltammetry？2026

March 7, 2026

How to determine electrochemical reversibility from cyclic voltammetry？ Description: This article delineates the methodology for evaluating the reversibility of electrochemical reactions using Cyclic Voltammetry (CV). The core criteria for assessment are the peak potential separation (ΔEp) between the anodic and cathodic peaks, and the peak current ratio (ipa/ipc). By incorporating the effects of scan rates, a comprehensive evaluation is conducted to distinguish between reversible, quasi-reversible, and irreversible redox processes. I. Definition of electrochemical reversibility？ Electrochemical reversibility specifically refers to the ability of an electrode reaction to rapidly achieve thermodynamic equilibrium during the transition between oxidized and reduced states, characterized by the absence of significant kinetic barriers. Its core feature is

Supercapacitors, Capacitors VS Batteries Source: WeChat Official Account “Learn Batteries Together” I. Charging and Discharging Principle of Supercapacitors: The difference between a capacitor and a battery: 1. Working Principle Capacitor: Stores energy through an electric field, with charge accumulating between the electrodes and the dielectric. Battery: Stores energy through chemical reactions, which occur during charging and discharging. 2. Energy Density Capacitor: Low energy density, suitable for short-duration energy release. Battery: High energy density, suitable for long-duration energy supply.   The defining characteristic of supercapacitors is the use of an electrolyte containing anions and cations—similar to that used in batteries—to replace the dielectric material found in conventional capacitors. When a supercapacitor
