,
the eighth revision of the United Nations Manual of Tests and Criteria incorporates the revisions of the seventh revision of the Manual of Tests and Criteria and its Amendment 1 made by the Committee of Experts at its tenth (11 December 2020) and eleventh (9 December 2022) sessions.
among them, the most important changes in the battery field are: the new sodium ion battery test requirements.
in the 23rd revision of the Model Regulations of the Recommendations on the Transport of Dangerous Goods published this year, an exclusive entry has been officially introduced for sodium-ion batteries, UN 3551,UN 3552.
similar to lithium batteries, sodium-ion batteries also need to pass the UN38.3 test before transportation. In this update, the 8th revision of the United Nations "Manual of Tests and Standards" revised chapter 38.3 to standardize the test of sodium-ion batteries.
so what are the differences between sodium ion batteries and lithium ion batteries in test methods?
1. Test 6: Heavy Impact/Crush (Test T.6: Impact/Crush) test, for single cell and single cell battery pack, the test will be carried out under full power;
2. No need to carry out test 8: Forced discharge (Test T.8: Forced discharge).
