Teach you how to read lithium batteries.

Combined with domestic and foreign history and current usage of words, this paper summarizes and collates the common definitions, terms, and nouns of lithium batteries in research and development, and interprets some of them that are easily ambiguous.

The relevant documents have been submitted to the National Technical Committee for Standardization of Alkaline Battery in the Information Standards of the Electronic Industry of the Ministry of Industry and Information Technology of the People's Republic of China. This is a draft, informal release text, the marked part will not appear in the official release of the document, please refer to the official release text, this text is for reference only.

1. Scope

The standard specifies general terms for lithium batteries, including lithium primary batteries and lithium battery related terms. GB/T2900.41 -2008 and the terms specified in this standard apply to lithium batteries (abbreviated as "batteries"). When the two are inconsistent, this standard shall prevail.

3. Terminology and definitions

3.1 Basic concepts

3.1.1 Lithium primary battery (lithiumprimarybattery)

Also known as a lithium battery, negative lithium, and designed as a non-rechargeable battery. Including monomer lithium primary cells and lithium primary batteries.

3.1.2 Lithium batteries (regeablelithiumbattery)

Lithium-ion batteries and lithium-metal batteries are collectively referred to as lithium batteries (also known as rechargeable lithium batteries, secondary lithium batteries).

3.1.3 lithium ion battery (lithiumionbattery)

Lithium ions are used as conductive ions to move between positive and negative poles, and batteries that are charged and discharged are converted by chemical energy and electrical energy. Including single lithium ion cells and lithium ion batteries.

3.1.4 Single lithium ion battery (lithiumioncell)

The basic unit of a lithium-ion battery consists of an electrode, a diaphragm, a housing, and an electrode sheet in an electrolyte environment.

3.1.5 Lithium metal batteries (regeablelithiummetalbattery)

Lithium batteries with metallic lithium on the negative side of the battery. Also known as rechargeable lithium metal batteries. Note: In the process of battery assembly, the negative electrode can be completely metallic lithium, or some of it contains metallic lithium. During the battery cycle, the form of metallic lithium exists in the negative electrode, and electrochemical deposition and precipitation occur reversibly.

3.1.6 Liquid lithium batteries(liquidregeablelithiumbattery)

Lithium batteries containing only liquid electrolytes.

3.1.7 Non-aqueous organic solvent lithium battery(nonaqueousregeablelithiumbattery)

Electrolytes are liquid lithium batteries with organic solvents.

3.1.8 Lithium water batteries (aqueousregeablelithiumbattery)

The electrolyte is a liquid lithium battery with a water solvent.

3.1.9 Hybrid solid electrolyte lithium battery (mixedsolidliquidelectrolyteregeablelithiumbattery)

Lithium batteries containing both liquid and solid electrolytes.

Note: There are many terms in the literature for this type of battery. 1 The mass or volume of solid electrolytes in the battery monomer accounts for half of the total electrolyte mass or the total volume of the monomer, or the electrode on one side of the monomer contains liquid electrolytes. The other electrode contains only solid electrolytes. Both of these are called semi-solid lithium electrolyte batteries, sometimes referred to simply as semi-solid lithium batteries; 2 The mass or volume fraction of a solid electrolyte in a monomer is more than half, and the mass or volume fraction of a liquid electrolyte is less than half, sometimes referred to as a quasi-solid electrolyte lithium battery or a quasi-solid lithium battery; 3 Liquid electrolytes whose mass or volume fraction is less than 5 % of the total mass or total product of the electrolyte, some authors call solid electrolyte lithium batteries, or solid lithium batteries. However, in fact, the battery monomer contains a small amount of liquid electrolytes, which is called a solid lithium battery. It is more suitable for being called a quasi-solid electrolyte lithium battery or a quasi-solid lithium battery. The semi-solid electrolyte lithium battery, quasi-solid electrolyte lithium battery, and solid electrolyte lithium battery that appear in the above documents belong to the mixed solid electrolyte lithium battery, referred to as the mixed solid electrolyte lithium battery. English can also be called Hybridsolidliquidelectrolyteregeablelithiumbattery.

3.1.10 All-solid lithium batteries (allsolidstateregeablelithiumbattery)

The battery monomer contains only solid electrolytes and does not contain any liquid electrolytes, liquid solvents, and liquid additives.

3.1.11 Lithium battery for gel polymer (gelpolymerregeablelithiumbattery)

Lithium batteries in which liquid electrolytes and polymer polymers form gelatinous electrolytes. Note: Soft packaged lithium-ion batteries that currently encapsulate plastic seals are also called polymer lithium-ion batteries, sometimes referred to simply as polymer lithium-ion batteries. Gel polymer electrolyte lithium battery refers to the electrolyte within the diaphragm and positive and negative poles in the form of gel polymer electrolytes. There are great differences in composition and performance between the two.

3.1.12 Semi-solid lithium batteries (half-solidstatelithiumbattery)

Either of the electrodes in the battery does not contain liquid electrolytes, and the other electrode contains liquid electrolytes. Or the solid electrolyte mass or volume in the monomer accounts for half of the total electrolyte mass or total volume ratio in the monomer.
