SECONDARY CELLS AND BATTERIES CONTAINING ALKALINE OR OTHER NON-ACID ELECTROLYTES – SECONDARY LITHIUM CELLS AND BATTERIES
FOR PORTABLE APPLICATIONS

37、 Scope
This International Standard specifies performance tests, designations, markings, dimensions and other requirements for secondary lithium single cells and batteries for portable applications.
The objective of this standard is to provide the purchasers and users of
38、 secondary lithium cells and batteries with a set of criteria with which they can judge the performance of secondary lithium cells and batteries offered by various manufacturers.
This standard defines a minimum required level of performance and a standardized methodol
39、ogy by which testing is performed and the results of this testing reported to the user. Hence, users will be able to establish the viability of commercially available cells and batteries via the declared specification and thus be able to select the cell or battery best suited for their
40、intended application.
This standard covers secondary lithium cells and batteries with a range of chemistries. Each electrochemical couple has a characteristic voltage range over which it releases its electrical apacity, a characteristic nominal voltage and a characteristic end-of-discharge volt
41、age during discharge. Users of secondary lithium cells and batteries are requested to consult the manufacturer for advice.
2 Normative references
