压实密度(compacted density)

 

. 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(dian)池(chi)在制作过程(cheng)中,压实(shi)(shi)密度对(dui)电(dian)池(chi)性能(neng)有较大(da)的(de)影响。通过实(shi)(shi)验证明,压实(shi)(shi)密度与片(pian)比容量,效率(lv),内阻,以(yi)及电(dian)池(chi)循环性能(neng)有密切的(de)关系(xi)。

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*佳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(ya)实(shi)密度(du)(du)不光和(he)颗(ke)粒的(de)(de)大小、密度(du)(du)有(you)(you)关系,还和(he)粒子(zi)的(de)(de)级配有(you)(you)关系,压(ya)实(shi)密度(du)(du)大的(de)(de)一(yi)(yi)般都有(you)(you)很好的(de)(de)粒子(zi)正态分布。可以认(ren)为,工艺条(tiao)件一(yi)(yi)定(ding)的(de)(de)条(tiao)件下,压(ya)实(shi)密度(du)(du)越(yue)大,电池的(de)(de)容(rong)量越(yue)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.

合适的正极压实密度可以增大电池的放电容量,减小内阻,减小极化损失,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.


.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.
