Foreword
This standard is in accordance with GB/T 1.1-2009 given rules drafted.
This standard replaces GB/T 20252-2006 "lithium cobalt oxide." This standard compared with GB/T 20252-2006 main technical changes are as follows.
--- Increasing the term clause;
--- Increasing the lithium cobalt oxide product classification;
--- Increased performance requirements of different types of lithium cobalt oxide;
--- Increasing the residual alkali content, magnetic foreign matter content requirements;
--- Change the primary element content and product requirements;
--- Modify the content of impurity elements and product requirements;
--- Modify the test items and sample content.
--- Remove the chemical composition of the two elements Li and Co content requirements molar ratio;
--- Remove the standard in Appendix A, Appendix B, Appendix C and Appendix D.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard was drafted. CITIC Guoan MGL Power Technology Co., Ltd., Guangdong loop Bump Technology Co., Ltd. Beijing when l material
