产品简介

FT-100F粉末自动压实密度仪 

FT-100F Powder automatic compaction density testing (updated version)

1.   定义:Definition

压实密度的计算公式:压实密度=面密度/材料的厚度

在锂离子电池设计过程中,压实密度=面密度/(极片碾压后的厚度—集流体厚度) ,单位:g/cm3

Compaction density calculation formula: the compaction density =surface density/ thickness of material

In the process of lithium ion battery design, compaction density = surface density / (The thickness of the pole plate  after crushing – current collector  thickness), unit: g/cm3

压实密度分为:负极压实密度Anode density(或称为阳极压实密度)和正极压实密度Cathode density(或称为阴极压实密度)。

Compaction density is divided into: the cathode compaction density (or is called the Anode compaction density) and the Anode compaction density (or called the Cathode compaction density)

. 原理: Principle:

锂离子动力电池在制作过程中,压实密度对电池性能有较大的影响,压实密度与片比容量,效率,内阻,以及电池循环性能有密切的关系。

In the process of making lithium ion power battery, The compacting density has a large effect on battery performance.The test results show that the compaction density is closely related to specific capacity, efficiency, internal resistance and the performance of the battery cycle.

压实密度越大,电池的容量就能做的越高,所以压实密度也被看做材料能量密度的参考指标之一。

.适用范围:Scope of application

在外力的压缩过程中,随着粉末的移动和变形,较大的空隙被填充,颗粒间接触面积增大,使原子间产生吸引力且颗粒间的机械楔合作用加强,从而形成具有一定密度和强度的压坯.

In the process of the compression of external force, As the movement and deformation of powder, larger gap is filled, The contact area between particles increases, The interatomic appeal and mechanical wedge cooperation between particles will be enhanced, Thus forming a certain density and intensity of compact.

参照标准:GBT 24533-2009 锂离子电池石墨类负极材料,附录L:粉末压实密度的测试方法,

Meet standard: GBT 24533-2009 lithium ion battery graphite type anode materials, appendix L: Test method of powder compaction density,

也可以用于具有类似特性之粉末和颗粒压实密度之测定;

It can also be used for the determination of powder and particle’s compaction density which have similar properties;
