FT-100F粉末自動壓實密度儀 (升級版)

FT-100FPowder automatic compaction density instrument (updated version)

壓實密度(compacted density)

 

. 定義:Definition

 

壓實密度的计算公式:壓實密度=面密度/材料的厚度

在锂离子电池设计过程中,壓實密度=面密度/(極片碾壓後的厚度—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

 

壓實密度分为:负极壓實密度Anode density(或称为阳极壓實密度)和正极壓實密度Cathode density(或称为阴极壓實密度)。

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,壓實密度对电池性能有较大的影响。通过实验证明,壓實密度与片比容量,效率,内阻,壹s暗绯匮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*佳壓實密度对电池设计很重要。一般来说,壓實密度越大,电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.


壓實密度不光和颗粒的大小、密度有关系,还和粒子的級配有关系,壓實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,壓實密度越大,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.

合适的正极壓實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。在壓實密度过大或过小时,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.


.適用範圍: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,使原子間産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.
