Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces YS/T 677-2008 "lithium manganate". Compared with YS/T 677-2008, the main technical changes of this standard are as follows.
--- increase the normative reference documents;
- Added terms of terms;
--- increase the classification of lithium manganese oxide products;
--- increase the performance requirements of different types of lithium manganate;
--- increase the magnetic foreign body content requirements;
--- modified the main elements of the product content and requirements;
--- modified the impurity element content and requirements of the product;
--- to remove the chemical composition of the product Li and Mn two elements in the molar ratio requirements;
--- increase the 55 ℃ high temperature cycle test conditions;
- delete Appendix A, Appendix B, Appendix C, Appendix D.
This standard is proposed by the National Committee for Standardization of Nonferrous Metals (SAC/TC243).
