一. 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/(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：负压实密度Anode density（或称为阳压实密度）和正压实密度Cathode density（或称为阴压实密度）。

二. 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。通过实验证明，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.

找出压实密度对电池设计很重要。一般来说，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。

It is important to find the optimal compaction density for battery design.Generally speaking, the higher the density, the higher the capacity of the battery, so the compacted density is also seen as a reference indicator of the energy density of the material.

压实密度不光和颗粒的大小、密度有关系，还和粒子的级配有关系，压实密度大的一般都有很好的粒子正态分布。可以认为，工艺条件一定的条件下，压实密度越大，电池的容量越高。

The compaction density is not only related to the size and density of the particle, but also related to the level of the particle, Normally, High compaction density has a good particle normal distribution.It can be said that under certain conditions ,The higher density of the battery, the higher capacity of the battery.

合适的正压实密度可以增大电池的放电容量，减小内阻，减小化损失，延长电池的循环寿命，提高锂离子电池的利用率。在压实密度过大或过小时，不利于锂离子的嵌入嵌出。

The proper positive electrode compaction density can increase the discharge capacity of the battery, reduce the internal resistance, reduce the loss of polarization, extend the cycle life of battery, Improve the utilization rate of lithium ion batteries. If the The compacted density is too large or too small , It is bad for the embedding of lithium ions.

三.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增强，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.

满足标准：GBT 24533-2009 锂离子电池石墨类负材料，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,
