Manganese-Based Li-ion Cell Manufacturer
Powering the Products the World Relies On
Since 2015, Minmetals East has engineered high-reliability 18650 and 14500 lithium-ion cells for consumer electronics — supplying power tool, lighting, audio and smart home brands in the United States, Europe, Southeast Asia and India.
Who We Are
A focused lithium-ion manufacturer built for long-term partnerships
Henan Minmetals East Energy Co., Ltd. is a national high-tech enterprise founded in 2015, specialising in manganese-based lithium-ion batteries and manganese lithium oxide cathode materials. We operate three production bases — Jiaozuo, Xinxiang and Chengdu — and deliver to OEM and brand customers worldwide.
Our 18650 and 14500 manganese-based cells rank among the leading global market share positions in the consumer battery segment, a position we have maintained continuously since the company was founded.
We build the full operational chain ourselves: quality raw material supply, advanced production and manufacturing, efficient logistics distribution and responsive after-sales service. This is backed by more than 50 patents and recognition as the Henan Engineering Technology Research Center for Manganese-based Li-ion Batteries.
Discover our storyMaterial-to-cell integration
We produce our own LMO cathode material and cells, controlling chemistry, cost and consistency end to end.
Global certification coverage
UL, BIS, PSE, CB, REACH, RoHS, EU Battery Directive and UN38.3 — certified for the markets you ship to.
Engineering support
Cell selection, pack configuration and custom formats supported by our own R&D and application engineers.
Product Center
Two cell families, engineered for different duty cycles
Digital-grade cells prioritise runtime and energy density. Power-grade cells prioritise sustained high-current output and low internal resistance.
IMR / INR 14500 & 18650
Digital Grade
High reliability, long battery life, wide temperature range and long service life. The standard choice for power tools, e-toys, power banks, portable lighting, smart speakers and smart home devices.

IMR / INR 14500 & 18650
Power Grade
High-rate discharge up to 5.0C, low internal resistance and stable high-current output for demanding applications such as power tools, vacuum cleaners, RC models and high-power devices.
View power-grade cellsWhat Sets Us Apart
Capability that removes risk from your supply chain
Self-supplied cathode material
20,000 t per year of lithium manganese oxide produced in-house, giving us full control over chemistry consistency, qualification cost and supply continuity.
Three-base manufacturing network
Jiaozuo, Xinxiang and Chengdu give us flexible volume allocation, regional logistics reach and redundancy for your delivery commitments.
Automated, traceable production
Fully automatic coating, winding and assembly lines with in-line thickness, defect and electrolyte-volume measurement on every critical step.
Ten-thousand-class clean room
Class 10,000 clean-room production and assembly, with dedicated climate control and ESD protection throughout the cell finishing process.
Manufacturing
From raw powder to a finished cell in eleven controlled steps
Every cell passes through an eleven-stage process with in-line measurement at the coating, winding, filling and sorting stages — producing traceable, repeatable quality at 16 million cells a day.
- Automatic mixing under vacuum with dosing by weight
- In-line electrode thickness and defect detection
- X-ray inspection on every wound jelly roll
- Capacitance, OCV and internal-resistance grading
Quality Assurance
Certified for the markets you sell into
ISO 9001 and ISO 14001 management systems, seven international product approvals and a full UN38.3 transport certification package support every shipment we make.
Applications
One cell platform, dozens of consumer products
From cordless drills to headlamps, water fountains and smart speakers — our cells are engineered into products that people use every day.
Power Tools
Cordless drills, cutters and outdoor equipment requiring sustained current in vibration-prone housings.
Portable Lighting
Headlamps, torches and LED bulbs where runtime and cold-start behaviour decide the product.
Smart Audio & Home
Smart speakers, soundbars and home devices running on standby-tolerant, long-life cells.
Toys & Entertainment
Electronic toys, RC models and gel blasters needing an inexpensive, dependable cell.
Power Banks & Portable Power
Mobile power with strict capacity grading so that the advertised output is real output.
Personal Care & Small Appliances
Oral irrigators, shavers, blenders and aroma diffusers — high-frequency, low-duty devices with tight cost targets.
