Battery grade anhydrous lithium chloride
1 Scope
This Standard specifies the requirements, test methods, inspection rules and marking,
packaging, transportation, storage, quality certificate and order form (or contract)
content of battery grade anhydrous lithium chloride.
This Standard applies to anhydrous lithium chloride produced from various raw
materials. The product is mainly used for one-step electrolysis to produce battery grade
metallic lithium. It can also be used to manufacture welding materials, air conditioners,
and as a catalyst for the synthesis of polymer materials.
2 Normative references
The following referenced documents are indispensable for the application of this
document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
GB/T 1480 Determination of particle size for metallic powders - Dry sieving
GB/T 11064 (all parts) Methods for chemical analysis of lithium carbonate, lithium
hydroxide monohydrate and lithium chloride
GB/T 13025.2 General test method in salt industry - Determination of whiteness
GB/T 13025.3 General test method in salt industry - Determination of moisture
3 Requirements
3.1 Chemical composition
The chemical composition of the product shall comply with the requirements in Table
1.
Products shall be submitted for acceptance in batches, each batch consisting of the same
mixture. The net weight of each batch shall not exceed 5 t.
5.3 Inspection items
Each batch of products shall be inspected for chemical composition, physical properties,
and appearance quality.
5.4 Sampling and sample preparation
5.4.1 Lithium chloride is a strongly hygroscopic material, and its representativeness
shall be ensured every time when a sample is taken.
5.4.2 Randomly take 1 bag from less than 10 bags; randomly take 2 bags from 10 ~ 20
bags; randomly take 4 bags from more than 20 bags.
5.4.3 Stainless steel tubes or hard polyethylene samplers are used for product sampling.
The sampling tube is inserted along the center of the bag to 2/3 of the bag. After the
sample is mixed, it is divided into about 300 g using the quartering method in a dry
environment.
5.5 Determination of inspection results
5.5.1 If the chemical composition analysis results are inconsistent with the provisions
of this Standard, double sampling is allowed to carry out repeated test for unqualified
items. If there is still one unqualified result after repeated test, the batch will be
determined unqualified.
5.5.2 If the moisture content is unqualified, the batch will be determined unqualified.
5.5.3 If the appearance quality inspection fails, the batch will be determined unqualified.
5.5.4 If the particle size quality inspection fails, the batch will be determined
unqualified.
5.5.5 If the whiteness quality inspection fails, the batch will be determined unqualified.
6 Marking, packaging, transportation, and storage
6.1 Marking
The outer packaging bag of the product shall indicate:
a) name of supply party;
b) product name;
c) batch number;
