Introduction

Core Value and Technical Positioning of the Standard

As a key lithium supplement additive for lithium-ion battery cathode materials, lithium-rich iron oxide significantly improves the initial efficiency of the battery through a high lithium supplement capacity of more than 700mAh/g. This standard establishes a complete quality evaluation system for the first time, filling the gap in domestic technical specifications in this field.

Analysis of key technical indicators

Performance parameters	LFO-I grade	LFO-II grade	LFO-III grade	Test standards
Lithium replenishment capacity	≥700mAh/g	650-700mAh/g	600-650mAh/g	GB/T 42161
Tap density	≥1.0g/cm³			GB/T 5162
Specific surface area	≤3.0m²/g			GB/T 19587

Application Case: Lithium Supplementation in High Nickel Ternary System

A battery company uses LFO-I grade materials to increase the first efficiency of the NCM811 system from 86% to 92%, and extend the cycle life by 30%. The key technology is to control the material's pH value in the range of 11-13 to avoid electrolyte decomposition.

Key points for implementation of the standard

Key control for detection

Moisture detection must use the Karl Fischer method (GB/T 6283), controlled at ≤0.05%
Particle size distribution must meet the strict normal distribution requirements of D50:4-18μm
Moisture resistance test must be carried out at 24±1℃/30±2%RH

Quality assurance system construction

Inspection type	Frequency	Core items	Judgment rules
Batch inspection	Each batch	12 items including chemical composition, moisture content, etc.	A single item failure will result in scrap
Periodic inspection	Monthly	Crystal structure	Compare with JCPDS standard atlas
