In today's lithium battery manufacturing field, the battery roll press (referred to as the roll press) is undoubtedly an indispensable equipment. With its unique rolling process and high production efficiency, it provides a strong guarantee for the energy density improvement, life extension and performance optimization of lithium batteries. Battery roll press has become one of the indispensable key equipment in modern battery manufacturing industry due to its high efficiency production, high quality electrode, flexible and adjustable, energy saving and environmental protection.
1. What is a battery roll press?
Battery roll press is a key equipment for battery manufacturing, mainly used to prepare positive and negative battery materials. It works by evenly mixing materials such as active substances, conductors and binders through a series of rollers, and extruding them into electrode sheets of the desired shape and thickness under specific temperature and pressure conditions.
2.the working principle of battery roll press machine
The working principle of the battery roll press is relatively simple and efficient. The core is to continuously roll the lithium battery through one or more pairs of rollers, and the active substance and conductive agent in the battery are laminated together. This process is similar to the working principle of a noodle machine, through the rotation and pressing of the roller wheel, the electrode material is pressed into a sheet structure with a certain thickness and shape.
The specific working process is as follows: First, adjust the spacing between rollers according to the thickness requirements of the battery; Then, the battery is placed in the guide device; Then, the roller press machine is opened, and the driving mechanism provides power to make the roller wheel start to rotate; Finally, the battery enters the roller pressing area from the guide device, and through the continuous pressing of the roller wheel, the various layers of materials in the battery are closely chimed to complete the roller pressing process. After the completion of roller processing, the battery is discharged from the guide device on the other side, and then the subsequent battery assembly and production process is carried out.
3. Technical parameters of battery roller press
The technical parameters of the battery roll press machine have an important influence on the performance and application range of the equipment. Here are some key technical parameters:
(1) Equipment models and specifications: roller press has a variety of models and specifications, according to production needs and capacity to choose the right equipment. Equipment models and specifications will affect production efficiency, material handling capacity and other aspects.
(2) roll pressure and pressure regulation: roll pressure is one of the key performance indicators of the roll press, which directly affects the degree of compaction of the material. The pressure adjustment function allows the roller pressure to be adjusted within a certain range to meet the requirements of different materials and production processes.
(3) Roll diameter and roll speed: roll diameter and roll speed are another important factor affecting the roller effect. Suitable roll diameter can ensure that the material is subjected to uniform pressure during the rolling process; Reasonable roll speed can make the material achieve the ideal compaction effect in the rolling process.
(4) raw material adaptability: the roller press should have strong raw material adaptability and can handle a variety of positive and negative materials, such as graphite, silicon, lithium composite materials.
(5) Control system and safety: The high performance roller press should have a perfect control system to realize the automatic operation of the equipment. At the same time, the safety of the equipment can not be ignored, and it is necessary to ensure that the operator will not be harmed during operation.
(6) Energy consumption and environmental protection: While ensuring high performance, the roller press should have low energy consumption to reduce production costs. In addition, the equipment should also meet environmental requirements to reduce the impact on the environment.
4. Operation method of battery roll press
Operating a battery roll press requires certain skills and experience, the following are the general operating steps:
(1) Preparation
Ensure that the battery roll press is in a stable state and check that the equipment is operating properly. Prepare the required materials and tools according to the production plan, including active substances, conductors, binders, etc.
(2) Adjust equipment parameters
The pressure, temperature and speed of the roller press are adjusted according to the requirements of the electrodes prepared. Often, these parameters need to be optimized based on the production process and the materials used.
(3) Prepare electrode materials
The active material, conductive agent and binder are mixed evenly according to a certain proportion to ensure the performance and quality of the electrode sheet. The mixed electrode material is loaded into the feed system of the battery roll press for subsequent extrusion and molding
Start the battery roll press to ensure the normal operation of the equipment. The pre-prepared electrode material is fed into the press roll area of the roll press, and the material is compressed into the electrode sheet of the desired thickness and shape through the extrusion and rolling of the roller. Monitor the parameter changes in the production process and adjust the equipment parameters as needed to ensure the stable and reliable quality of the produced electrodes.
(5) Complete production
When the production is complete, stop the operation of the battery roll press, and take out the finished electrode sheet for subsequent processing or packaging to clean and maintain the equipment, to ensure that the equipment is in good condition for the next production.
5.the advantages of battery roll press:
battery roll press as a key equipment in battery manufacturing, plays an irreplaceable role in the field of modern energy storage. It has many advantages that make the battery roll press one of the core processes in the battery manufacturing industry. Here are some of the main advantages of battery roll presses:
