简单介绍:
电池压实密度仪,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,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。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加强,从而形成具有一定密度和强度的压坯.电池压实密度仪

1. 定义:Definition

压(ya)(ya)实(shi)密(mi)度的计(ji)算(suan)公(gong)式:压(ya)(ya)实(shi)密(mi)度=面密度/材料的厚度

在锂离子电池设计过程中(zhong),压实密(mi)度=面(mian)密(mi)度/(极片碾压后(hou)的厚度(du)—集(ji)流体厚度(du)) ,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

电池压实密度仪 

压(ya)实密度(du)分为(wei):负极(ji)压(ya)实密度(du)Anode density(或称为阳极(ji)压(ya)实密(mi)度)和正极(ji)压(ya)实密(mi)度Cathode density(或称(cheng)为阴极(ji)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(li): Principle:

电池压实密度仪 

锂离子动力电(dian)池在制作过程中,压实(shi)密度(du)对(dui)电(dian)池性(xing)能(neng)有(you)较大的影响(xiang),压实(shi)密度(du)与(yu)片比容量,效(xiao)率,内阻,以(yi)及电(dian)池循环性(xing)能(neng)有(you)密切的关(guan)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.

压实(shi)密度(du)(du)越大,电池的(de)容量就能做(zuo)的(de)越高,所以压实(shi)密度(du)(du)也被看(kan)做(zuo)材料能量密度(du)(du)的(de)参(can)考指标之一(yi)。

.适用范围:Scope of application

电池压实密度仪 

在外力的(de)(de)压缩过程中,随着粉(fen)末的(de)(de)移动(dong)和变形(xing),较大的(de)(de)空隙被填充,颗(ke)粒间(jian)接触面(mian)积增大,使原子间(jian)产生吸引力且颗(ke)粒间(jian)的(de)(de)机械楔(xie)合作用加强,从(cong)而形(xing)成具(ju)有一定密度和强度的(de)(de)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.
