Mixing(配料)

Mix solvent and bound separately with positive and negative active materials. Make into positive and negative pasty materials after stirring at high speed till uniformity.

Coating(涂布)

Now, we are in coating line. We use back reverse coating. This is the slurry-mixing tank. The anode(Cathode)slurry is introduced to the coating header by pneumaticity from the mixing tank. The slurry is coated uniformly on the copper foil, then the solvent is evaporated in this oven. (下面的依据情况而定)There are four temperature zones, they are independently controlled. Zone one sets at 55 degree C, zone two sets at 65 degree C, zone three sets at 80 degree C, zone four sets at 60 degree C. The speed of coating is 4 meters per minute.

You see the slurry is dried. The electrode is wound to be a big roll and put into the oven. The time is more than 2 hours and temperature is set at 60 degree C.

Throughout the coating, we use micrometer to measure the electrode thickness per about 15 minutes. We do this in order to keep the best consistency of the electrode.

Cutting

Cut a roll of positive and negative sheet into smaller sheets according to battery specification and punching request.

Pressing

Press the above positive and negative sheets till they become flat.

Punching

Punching sheets into electrodes according to battery specification,

Electrode

After coating we compress the electrode with this cylindering machine at about 7meters per minute. Before compress we clean the electrode with vacuum and brush to eliminate any particles. Then the compressed electrode is wound to a big roll. We use micrometer to measure the compressed electrode thickness every 10 minutes. After compressing we cut the web into large pieces. We tape the cathode edge to prevent any possible internal short. The large electrode with edge taped is slit into smaller pieces. This is ultrasonic process that aluminum tabs are welded onto cathodes using ultrasonic weld machine. We tape the weld section to prevent any possible internal short. And finally, we clean the finished electrodes with vacuum and brush.

Anode making

In anode making process, we cut the material into certain length strips. At the mean time, we put a small piece of insulation tape to the tab in order to prevent any possible internal short. Then the prepared nickel tab is riveted on anode and pat plain. We also tape the rivet section to prevent any possible internal short. And finally, we clean the finished electrodes with vacuum and brush.

Jelly roll

This is Jelly roll, a manual winding process. In the course of Jelly roll, firstly, we place the separator in between central pins, press the foot switch to turn central pins about 120 degrees. Secondly, place the anode to the edge of central pins, and turn central pins about 180 degrees. Lastly, place the cathode to the edge of central pins. During the winding process, we apply tension by pressing the electrodes and the separator. We put the termination tape at the end.

After Jelly roll, we check the short circuit, then form the Jelly roll by pressing, so that it is easier to insert the Jelly roll into the can.

Control points:

1. When winding to the end of the anode, covering the anode completely by the separator.

2. In the whole process, it is the most important points to ensure the best alignment among the cathode, the anode and the separator for the Jelly roll. The separator has to cover the anode and the cathode, and the anode has to cover the cathode completely. These points are mainly checked before short checking.

Taping & inserting

Put the tape on the two side of J/R, To prevent J/R being hurt in the insertion process.

Put a piece of tape between cathode tab and J/R .Because anode electrode is wider than cathode electrode.

Put the bottom tape.

Insert the finished J/R into the can manually and then short circuit check by multi-meter.

Spot welding Ni tab to cap.

Ultrasonic welding the Al tab to cap using ultrasonic weld.

We have the second spot welding to ensure the best contact between the tab and cap.

Apply top insulator, to prevent Ni tab contacting with can.

Final J/R insertion by the centrifuge.

Laser welding

This is the Laser welding room! The first process is welding for the aluminum cap, specially connect the rivet with the weld plate to prevent the cell impedance excursion.

The second process is the Laser seam welding. In the process, it must ensure the intensity and airproof characters of the weld.

After the cell is welded, we would perform the leak checking, the short circuit checking and the weighing checking.

Oven drying electrolyte filling and storing

This is the process of cells oven drying at 80℃ for more than 12 hours under vacuum. After oven drying, the cells are transferred to the process of electrolyte filling through this channel. The electrolyte filling performs in dry room. The electrolyte is injected in two times so that it can be filled easily and sufficiently. When filling, vacuum first, then inject electrolyte. After that, we repeat vacuum and vent to room pressure several times. Finally the cell is put off at room pressure, then weigh the cell in order to check the amount of electrolyte. After weighing, we seal with tape onto the filling port to prevent the cells absorbing water during storing.

We store the filled cells for 24 hours at room temperature so that the electrolyte can be saturated sufficiently by the anodes and cathodes.

Pre-charge and ball seal

At first, we place a piece of absorb cotton above the filling port to absorb the excess electrolyte. This is the first process.

The second process is performing a pre-charge at 0.1C rate for 390 minutes.

After the pre-charge, we take a voltage checking to the cell at once. If the voltage is lower than the standard, it needs to be re-charged.

The fourth process is the ball seal. we must complete this process in 15 minutes.

First, put the steel ball in the right place. Then, give pressure to it so that the steel ball can fill the filling port.

In the whole process, we must make sure that the temperature and humidity are in the regular range.

Finally, the process is cleaning to eliminate the electrolyte on the cell surface with acetone solvent.

Aging and Formation

This is the aging room. We age cells at 35~40 Degree C for 7 days. The temperature is controlled by two heating instruments which are set at 38 Degree C. Then we transfer cells to the testing workshop. First, we check the voltage of cells with multi-meters. According to voltage, we divide the cells into acceptables and defects. Formation is done at 1.0 Capacity rate for 140 minutes to 4.2 Voltage. After that, check thickness and impedance. At last, we transfer the acceptables to the storehouse.

《安全管理》之聚合物锂电池的生产流程安全问题

聚合物锂电池的生产流程安全问题 在聚合物锂离子电池的生产过程中,以下一些因素必须予以注意。生产出的聚合物锂离子电池经过包装后,进行化成。化成的条件比较关键,因为它涉及SEI膜的形成,以防止负极自发与电解液发生反应;同时,也可以使活性物质与电解质之间有良好的接触。一般而言,每一个生产厂家有自己的化成条件。 聚合物锂离子电池/原材料 1 对于负极而言,除了使用溶于有机溶剂的聚合物作为黏合剂外,也可以使用溶于水溶液的聚合物作为黏合剂。图5为一种可溶于水的黏合剂聚(丙烯酰胺-共-二烯丙基二甲基氯化铵)(AMAC)的结构示意图。它与聚偏氟乙烯相比,具有一定的优越性,有利于在负极表面形成导电性更高的SEI膜,有机电解液的渗透性更好。2 导电剂的分散尽管不是重要方面,但也不可忽视。前面已经讲述了导电剂的分散情况对于负极材料的影响,对于正极材料而言也起同样作用,影响正极容量的发挥和电池的倍率性能。例如对于LiMn2O4而言,采用新型的工艺比传统的工艺更能保证导电剂分散均匀,极化低,容量高,倍率性能好。不同工艺制备的LiMn2O4正极极片的容量与放电倍率的关系。3 正极和负极的比例对于不同的原材料而言也是不一样的。例如,对于天然石墨//LiFePO4而言,后者的容量应该等于天然石墨的容量与SEI膜形成所需要的电荷之和。另外,电极的厚度根据不同的材料,也有不同要求。4 目前商品用的聚合物锂离子电池基本上还是使用LiFP6的碳酸酯溶液作为增塑剂,在较高的温度(80~100℃)下,在微量水分或醇的引发下发生分解,并产生一些有毒的烷基氟化磷酸酯。该热分解在路易斯酸或锂和金属的复合氧化物的作用下受到抑制。5

锂电池生产工艺分析

锂电池生产工艺分析 关于循环不合格的分析 一、正负极活性材料的物化结构性质的影响 正负极活性材料的物化结构性质对锂离子的嵌入和脱嵌有决定性的影响,因而影响电池的循环寿命。正负极活性材料的结构是主要的影响因素,使用容易脱嵌的活性材料充放电循环时,活性材料的结构变化较小,而且这种微小变化是可逆的,因而有利于延长充放电循环寿命。 1、材料在充放电过程中的结构稳定性 材料在充放电过程中的结构稳定性有利于提高其充放循环性能。如尖晶石材料LiXMn2O4,具有优越的循环性能,其主要原因之一便是在锂离子的嵌入和胶出过程中,单元晶胞膨胀、收缩率小于1%,即体积变化小;LiXMn2O4(X大于等于1)电极 在充放过程中容量损失严重,主要是因为在充放电过程中,其颗粒表面发生Jahn-Teller畸变效应,单元晶胞膨胀严重,使结构完整性破坏。对材料进行适当的离 子掺杂可有效提高材料的结构稳定性。如对尖晶石结构LiXMn2O4进行适量的钴(Co)掺杂,因钴使该材料的晶格参数变小,在循规蹈矩环过程中晶体结构趋于稳定,从而有效改善了其循环稳定性。 2、活性材料的料度分布及大小影响 活性材料的粒度对其循环性能影响很大。研究表明:活性材料的粒度在一定范 围与材料的循环性能正相关;活性材料的粒度分布越宽,其循环性能就越差,因为当粒度分布较宽时,其孔隙度差,从而影响其对电解液的毛细管作用而使阻抗表现较大,当充电到极限电位时,大颗粒表面的锂离子会过度脱嵌而破坏其层状结构,而不利于循环性能。 3、层状结构的取向性及厚度的影响

具有高度取向性和高度层状有序结构且层状结构较厚的材料,因锂离子插入的方向性强,使用其大电流充电放循环时性能不佳,而对于一些具有无序性层状结构(混层结构)或层结构较薄的材料,由于其锂离子脱嵌速率快,且锂脱嵌引起的体积变化较小,因而其充放循环过程中容降率较小,且耐老化。 4、电极材料的表面结构和性质的影响 改善电极材料的表面结构和性质可有效抑制有机溶剂的共插入及其与电解液间的不良反应,如在石黑表面包覆一层有机聚合物热解碳,在一些正极活性材料如LiCOO2,LiC0XNi1-XO2等表层涂覆一层玻璃态复合氧化物如 LiO-Al2O3-SiO2,Li2O-2B2O3等可显著改善材料的充放电循环性能及电池的安全性。 二、电极涂层粘结强度的影响 正负极涂层的粘结强度足够高时,可防止充放循环过程中正负极优其是负极的粉化脱落或涂层因过度膨胀收缩而剥离基片,降低循环容降率 ;反之,如果粘结强度达不到要求,则随循环次数的增加,因涂层剥离程度加重而使电池内阻抗不断增大,循环容量下降加剧。具体说来,包括以下几方面的因素。 1、胶粘剂的材料选择 目前常用的粘合剂为水溶性有机氟粘合剂(PVDF,PTFE等),其粘结强度受物理化学性能参数如分子量、热稳定性、热收缩率、电阻率、熔融及软化温度以及在溶剂中的溶胀饱合度、化学稳定性等的影响;此外,正极和负极所用的粘结剂及溶剂均要非常纯,以免因杂质存在而使电极中的粘结剂氧化和老化,从而降低电池的循环性能。 2、胶粘剂的配制 选用合适的粘合剂与溶剂相互作用后形成胶粘剂,它对涂膜有较强的附着力,但要注意配制时的温度、各组分间的比例,即配即用,不宜久放,涂好的极片也不
