According to the national standard Coding Rules for Lithium-Ion Batteries, starting from November 1, 2025, every newly produced lithium-ion battery product will be assigned a unique identification code. This standard covers all product levels from individual cells to battery systems, enabling full-lifecycle management from production to recycling through the "one battery, one code" mechanism.
This means that everything from the small battery in your smartphone to the large power battery pack in electric vehicles will have its own unique "ID card."
How Piezoelectric Coding Achieves Precise Marking
Piezoelectric inkjet coders are popular high-precision, high-resolution industrial marking equipment in the battery industry. Adopting advanced piezoelectric ceramic technology, they drive ceramic deformation via voltage to squeeze ink chambers, producing micro-droplets for high-resolution marking. These coders can clearly print logos, icons, and text on the surfaces of cylindrical and rectangular batteries. Yeacode's piezoelectric inkjet coders combine precision inkjet technology with UV curing, offering both high accuracy and efficiency.
Core Advantages of Yeacode Piezoelectric Inkjet Coders
The world's first modular PIJ (Piezoelectric Inkjet) coder with freely combinable multi-printheads. A single printhead supports a maximum printing height of 108.3mm. Its compact modular design adapts to both small-size cells and large energy storage batteries, while enabling multi-angle operation for precise integration in space-constrained scenarios.
Yeacode offers a full range of printheads to meet diverse application needs: small to large sizes, low to high speeds, and medium-high to ultra-high resolution. For the battery industry's demand for high-definition marking, the Yeacode 8D/7TA series printheads are available with a resolution of up to 600 DPI, ensuring clear printing of micro-characters.
Optional printhead-level ink circulation system guarantees stable, low-maintenance printing for long periods. Specialized inks are tailored for battery films and coated materials, providing strong adhesion with rework support as needed.
Yeacode's comprehensive SDK development kit and PC-based printing control software enable rapid response to custom requirements. Coding rules can be dynamically switched, production data is bound in real-time, and seamless integration with factory ERP/MES systems is achieved.
Industrial Upgrade, Empowering the Entire Battery Industry Chain
With the new battery industry regulations raising requirements for marking clarity and precision, traditional small-character dot-matrix coders can no longer meet the standards. Piezoelectric inkjet coders, renowned for "industrial-grade high precision, high resolution, and high-definition printing," are becoming the preferred choice in the battery industry.
From upstream material suppliers and battery manufacturers to downstream electric vehicle factories, energy storage system integrators, and battery recycling enterprises, data interconnection will be realized through unified coding rules. For consumers, the implementation of battery coding also brings tangible benefits, helping to effectively avoid risks such as inferior products.
