Scope

This document specifies a potentiometric method for the determination of the chloride content of lithium carbonate with an analytical range of 10 mg/kg to 650 mg/kg chloride.

Purpose

Lithium is a very light metallic element, used in particular for lithium batteries, in the glass and ceramics industries, some lubricants and some light alloys:

-Lithium (Li-ion) batteries (56%)-Glass and ceramics (22%), with improved thermal properties and viscosity

-Lubricating greases (6%)

-Rubber and plastics (4%)

-Metallurgical alloys (3%)

The main lithium-producing countries are Australia, Chile and Argentina (which together account for 87% of world mine production), with China and Zimbabwe far behind. New production plants are being launched around the world for Li-ion batteries to meet the demand for batteries for electric vehicles. The growing lithium market needs a framework, especially for chemical analysis and physico-chemical composition, thanks to ISO Standards.These standards will facilitate International trade by uniformizing test methos for identifying lithium quality. In parallel, it will reduce misunderstanding and trade litigation at the global level.
