压实密度(compacted density)


. 定义:Definition



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:



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.


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.


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.


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



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.
