Test method for compaction density of powder materials

The invention relates to the technical field of test equipment for lithium ion batteries, in particular to a test method for the compaction density of powder material. The test method includes the following steps:S1, weighing the mass m of a to-be-tested powder material;S2, carrying out briquetting processing on the o-be-tested powder material by a pressing machine (4) to obtain a compacted bulk material (1) with the cross section S; S3, measuring the height h of the bulk material (1); and S4, calculating the compacted density rho of the powder material based on a formula: rho=m/(h*S).According to the provided method, the powder material is directly subjected to briquetting treatment to obtain the compacted bulk material. The method has advantages of simple operation, short sample preparation time, and great convenience and the like; and a few of measurement data are required and thus testing is performed rapidly. 本发明涉及锂离子电池的测试设备技术领域，特别涉及一种用于粉体物料的压实密度的测试方法。所述测试方法包括以下步骤：S1：称量待测的所述粉体物料的质量m；S2：通过压力机(4)将待测的所述粉体物料
