In the primary lithium battery industry, consistency and reliability are the two core indicators that B-end customers pay most attention to when selecting models. Especially in application scenarios such as security, industrial instruments, and smart terminals that have extremely high requirements for battery performance, the stability of a battery often directly affects the life and operating efficiency of the equipment. Therefore, it is particularly important for buyers to have a deep understanding of the production process and quality control system of CR123A lithium batteries.
As a professional primary lithium battery manufacturer, Jiangmen Hongli Energy Co., Ltd. has always adhered to the "quality-oriented" principle and built a full-process quality control system around CR123A products from raw material screening, precision manufacturing to final inspection and shipment to ensure that every battery shipped has high consistency, low self-discharge, and high safety performance characteristics.
1. Strictly control raw materials and ensure quality at the source
High-quality CR123A batteries first come from high-quality raw materials. Hongli Energy selects high-purity electrolytic manganese and electrolyte, imported diaphragm materials, and maintains long-term cooperation with stable suppliers to ensure that each batch of incoming materials has stable composition and consistent physical and chemical properties. All raw materials must pass strict physical and chemical performance tests and small batch verification tests before entering the production process.
2. Automated production to improve consistency and efficiency
Hongli Energy introduced a fully automatic battery production line to achieve highly automated operations from pole piece manufacturing, winding, liquid injection, packaging to finished product testing, greatly reducing manual errors and improving product consistency. At the same time, the MES production traceability system runs through the entire process, recording the process parameters and quality data of each batch of products in real time to ensure that the production process is traceable and controllable.
3. Process control, full monitoring of key indicators
During the production process, Hongli Energy conducts online monitoring and sampling tests on a number of key performance indicators, including:
Capacity consistency (control error ≤±2%)
Self-discharge rate (monthly average ≤1%)
Voltage deviation is controlled within ±0.02V
Pole piece coating thickness and winding tension monitoring
The refined operation of these process control points is the key to ensuring the batch delivery of high-consistency batteries.
4. Comprehensive final inspection to ensure the factory qualified rate
In the finished product stage, Hongli Energy performs multiple rounds of high and low temperature cycle tests, voltage stability tests, short circuit/over-discharge protection tests and other projects to ensure that the battery can operate stably under various working conditions. All CR123A batteries shipped are 100% automatic voltage sorting and appearance inspection, and come with clear batch identification and test records.
Through strict control of the entire process, Hongli Energy's CR123A batteries not only achieve high consistency between batches, strong stability, and long service life, but also win OEM cooperation and long-term orders from customers in Europe, the United States, Japan, South Korea and other countries.
In the future, Hongli Energy will continue to increase investment in automation and intelligence, build a more efficient and transparent lithium battery quality management system, and continue to provide global customers with reliable CR123A power solutions.
