GB/T 47292.1-2026Lithium-ion battery good manufacturing practice - Part 1: General requirements (English PDF)

3.1 Lithium ion cell

A rechargeable device that achieves the conversion between chemical energy and electrical energy through the movement of lithium ions between the positive electrode and the negative electrode.

Note 1: It includes electrodes, separator, electrolyte, container and terminals, etc.

Note 2: Lithium ion cell is also generally referred to as "cell".

3.2 Lithium ion battery

An energy storage device consisting of one or more electrically connected cells or modules, capable of obtaining electrical energy from external sources and outputting electrical energy externally, and equipped with a battery management circuit.

Note 1: The battery management circuit usually has the functions of management or protection against overcharge, overcurrent, over discharge and/or overtemperature, so as to ensure the safety, performance and/or service life of the battery.

Note 2: The battery can be equipped with a protective enclosure and provided with terminals or other interconnection devices.

Note 3: The battery is also generally referred to as "battery pack" or "battery system".

3.3 Error-proofing

An engineering technology and management method that prevents errors, defects or accidents occurring in products or systems caused by human negligence, operation errors or unintentional actions from the source through design measures or process control.

6.1 Objective formulation

The formulation of production quality objectives shall comply with the following requirements.

a) Specificity: the production quality objectives shall be specified in detail;

b) Measurability: clear data shall be available as the basis for measuring the achievement of objectives;

c) Achievability: the objectives shall be designed in accordance with the actual capability and acceptance of the responsible parties, and conditions for implementation shall be available;

d) Relevance: the objectives shall be consistent with the company's quality policy and long-term and short-term objectives;

e) Time-bound: the specific time for achieving the objectives shall be specified.

6.2 Objective evaluation indicators

The evaluation indicators for quality objectives include but are not limited to.

a) Failure rate at customer side and market side;

b) Process yield rate;

c) On-time delivery rate;

d) Material and component qualification rate.

6.3 Objective management

Objective management shall comply with the following requirements.

a) Managers shall authorize designated organizations or personnel to regularly monitor the implementation of objectives of each department, and provide feedback of the monitoring results to the objective implementers;

b) The enterprise shall establish response plans. When deviations occur in objectives (including process objectives), the objective implementers shall formulate improvement measures and plans for the deviations according to the response plans, track the implementation of the measures, and confirm their effectiveness;

c) The enterprise shall establish an escalation mechanism. When significant deviations occur between results and objectives, the situation shall be reported to the management level to ensure that management can timely understand the implementation of objectives and provide instructions;

d) The enterprise shall continuously improve objective management.

7.1 Risk analysis

The enterprise shall establish a quality risk analysis mechanism. The risk level shall be determined by evaluating the risk impact scope, severity of consequences, probability of occurrence and detectability. The risk analysis shall include the following.

a) Lessons learned extracted from historical scrapping, rework, product recalls, customer complaints, product returns and repairs;

b) Collecting and identifying relevant requirements for product safety, laws and regulations, product performance and services;

c) Establishing manufacturing process FMEA related to product safety and performance, and identifying and implementing control and inspection methods for safety- and performance-related characteristics during production and manufacturing processes.

7.2 Risk control

7.2.1 The enterprise shall determine and implement preventive measures.

a) Preventive measures include measures for preventing abnormal occurrence and measures for preventing the release of abnormal materials (including battery materials, semi-finished products and finished products);

b) Preventive measures shall be consistent with the risk level.

7.2.2 The enterprise shall establish a risk mitigation mechanism to reduce potential negative impacts. The mechanism includes but is not limited to the following aspects.

a) Determine potential nonconformities and their causes.

b) Develop and implement control measures for preventing nonconforming items, and establish an identification and interception mechanism covering the whole process of incoming materials, production and finished products, including.

1) Requirements for battery material control;

2) Requirements for production process control;

3) Requirements for semi-finished product process inspection;

4) Requirements for performance inspection before finished products leave the production line;

5) Requirements for monitoring and evaluation of finished product safety and reliability after stable production of finished products.

c) Form control measures as standard documents.

d) Review the effectiveness of control measures.

e) Establish an experience and lessons learned transformation mechanism, incorporate corrective and preventive actions into quality management system standard documents, and prevent recurrence of similar problems.

7.3 Emergency management

7.3.1 For manufacturing processes and infrastructure equipment that maintain production output and conformity with customer requirements, the enterprise shall identify and evaluate relevant internal and external risks, establish emergency management specifications, and develop response plans according to the following situations.

a) Risks and impacts on customers;

b) Ensuring continuity of supply under any of the following circumstances.

1) Failure of key equipment;

2) Interruption of externally provided products, processes and services;

3) Common natural disasters; […]
