Lithium battery production numbering rules vary depending on the manufacturer, battery type and application scenarios, but usually contain the following common information elements and rules:
I. Manufacturer information:
Enterprise Code: The first few digits of the number usually represent the specific code of the producer, which is the key identification to distinguish different battery producers. The code is generally assigned by the relevant industry management department or set by the enterprise itself and for the record, to facilitate the traceability and management of the source of the battery. For example, certain large lithium battery producers will have an exclusive numerical or alphabetic combination code to identify their products in the market.
II. Product type information:
1. Battery type: this part of the code is used to distinguish the type of battery, such as lithium-ion batteries, lithium metal batteries and so on. For lithium-ion batteries, it may also be further subdivided into its cathode material system, common lithium iron phosphate batteries, lithium cobalt acid batteries, nickel-cobalt-manganese ternary batteries, etc., and each type is represented by a corresponding code. For example, according to a certain rule, “LFP” represents lithium iron phosphate, and “NCM” represents nickel-cobalt-manganese ternary material.
2. Product form: Lithium batteries are available in various forms, including cylindrical, square and soft pack. There may be specific letters or numbers in the number to indicate the shape of the battery. For example, “R” may indicate a cylindrical battery and “P” may indicate a square battery.
Third, performance parameter information:
1. Capacity information: Reflects the battery's ability to store power, usually in the form of a number. For example, “3000mAh” in a certain number indicates that the rated capacity of the battery is 3000mAh. For some large battery packs or systems, the total capacity value may be used.
2. Voltage information: Reflects the output voltage level of the battery, which is also one of the important parameters of battery performance. For example, “3.7V” means the nominal voltage of the battery is 3.7 volts. In some numbering rules, the voltage value may be encoded and converted to represent this information in a limited number of characters.
IV. Production date information:
1. Year: Usually, numbers or letters are used to indicate the year of production. Some manufacturers may directly use two digits to indicate the year, such as “22” for the year 2022; there are also some manufacturers will use a specific letter code to correspond to different years, in a certain order cycle.
2. Month: Generally, numbers or letters are used to indicate the month of production. For example, “05” means May, or a specific letter code to represent the corresponding month.
3. Batch or flow number: In addition to the year and month, there will be a batch number or flow number to indicate that the battery in the month or year of production order. This helps companies to manage the production process and quality traceability, but also reflects the production time sequence of the battery.
V. Other information:
1. Version number: If there are different design versions or improved versions of the battery product, the number may contain version number information in order to distinguish between different versions of the battery.
2. Safety certification or standard information: part of the number may contain codes related to safety certification or related standards, such as certification marking in compliance with certain international standards or industry standards, which can provide users with references about the safety and quality of the battery.
