How to Control Fixed Carbon Content? Essential Guide for Natural Graphite Anode Material Manufacturers

Introduction Why Does Your Anode Material Always Fail to Meet Customer Fixed Carbon Standards? As a natural graphite anode material manufacturer, have you encountered these challenges: ❌ Graphite from suppliers has significant batch-to-batch variation in fixed carbon content ❌ Despite heavy investment in chemical purification, product purity remains stuck around 98% ❌ Customers require fixed […]

How Does Fixed Carbon Content Affect Lithium Battery Performance? 4 Key Metrics Every Anode Material Manufacturer Must Know

Introduction If you’re a graphite anode material manufacturer, you’ve likely encountered these challenges: Why are customers so sensitive to a 0.5% difference in fixed carbon content? Can a 20% increase in purification costs truly deliver corresponding market returns? Power battery manufacturers require 99.5%+ purity—where are the technical barriers? The answer lies in a seemingly simple […]

What Is Fixed Carbon Content in Natural Graphite?

Introduction In the natural graphite anode material industry, you’ve likely heard customers make requests like: “We need spherical graphite with fixed carbon content ≥99.5%” “Can you provide stable supply of 99.9% high-purity graphite?” “Can your purification equipment increase carbon content from 94% to what level?” These seemingly simple numbers actually determine whether your product can […]

Understanding Natural Graphite Anode Particle Size and Its Impact on Battery Performance

Introduction In the production of natural graphite anode materials, particle size is often simplified as “particle dimensions,” but this parameter actually determines the material’s tap density, initial Coulombic efficiency, rate performance, and cycle life. A seemingly minor deviation in particle size can lead to several percentage points of initial efficiency loss or create lithium plating […]

Natural Graphite Morphology Classification: Types of Graphite You Should Know

Introduction In 2024, global new energy vehicle sales exceeded 14 million units, with each electric vehicle battery requiring 25-55 kg of graphite as anode material. The explosive growth of the lithium battery industry has thrust natural graphite into the supply chain spotlight. But a puzzling phenomenon persists: Why do natural graphites, seemingly identical, exhibit such […]
