一. 定義：Definition

壓實密度的計算公式：壓實密度=面密度/材料的厚度

在鋰離子電池設計過程中，壓實密度=面密度/(片碾壓后的厚度—集流體厚度) ，單位：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

壓實密度分為：負壓實密度Anode density（或稱為陽壓實密度）和正壓實密度Cathode density（或稱為陰壓實密度）。

二. 原理: Principle:

鋰離子動力電池在制作過程中，壓實密度對電池性能有較大的影響。通過實驗證明，壓實密度與片比容量，效率，內(nèi)阻，以及電池循環(huán)性能有密切的關系。

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.

找出壓實密度對電池設計很重要。一般來說，壓實密度越大，電池的容量就能做的越高，所以壓實密度也被看做材料能量密度的參考指標之一。

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.

壓實密度不光和顆粒的大小、密度有關系，還和粒子的級配有關系，壓實密度大的一般都有很好的粒子正態(tài)分布。可以認為，工藝條件一定的條件下，壓實密度越大，電池的容量越高。

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.

合適的正壓實密度可以增大電池的放電容量，減小內(nèi)阻，減小化損失，延長電池的循環(huán)壽命，提高鋰離子電池的利用率。在壓實密度過大或過小時，不利于鋰離子的嵌入嵌出。

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.適用范圍：Scope of application

在外力的壓縮過程中，隨著粉末的移動和變形，較大的空隙被填充，顆粒間接觸面積增大，使原子間產(chǎn)生吸引力且顆粒間的機械楔合作用增強，從而形成具有一定密度和強度的壓坯.

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.
