Preparation of Lithium Battery Slurry: Reasons for Slurry Deposition and Significant Changes in Viscosity and Solutions

In the manufacturing process of lithium batteries, slurry preparation is a crucial step. The quality of the slurry directly affects the electrochemical performance, production efficiency, and safety of the battery. In actual battery mixing machine production, problems such as slurry settling and large viscosity changes often occur, which affect the consistency of batteries. Analyzing the causes of these problems and finding effective solutions are of great significance for improving the production efficiency and stability of lithium batteries.   1、 Cause analysis 1). Unstable water absorption of slurry: The water absorption of slurry is an important factor affecting its stability. When the slurry absorbs too much water, it can cause changes in its composition, thereby affecting its physical properties such as viscosity. In addition, water absorption can also cause the solid particles in the slurry to condense, thereby accelerating the sedimentation of the slurry. 2). Insufficient adhesive: Adhesive is an important component in maintaining the stability of the slurry. If the adhesive content is insufficient, the viscosity of the slurry will decrease, leading to poor stability and easy sedimentation. 3). Poor dispersion effect: During the preparation process, if solid particles cannot be fully dispersed in the medium, it will lead to poor dispersion effect of the slurry, which will affect its stability. The agglomeration and sedimentation of solid particles can lead to inconsistent battery performance and may even cause safety issues for the battery.   2、 Solution 1). Adjust the selection of raw materials The selection of raw materials has a crucial impact on the stability of the slurry. Choosing appropriate raw materials, such as fillers and binders with lower water absorption, can effectively improve the stability of the slurry. In addition, optimizing the particle size and specific surface area of raw materials can also improve the dispersion and viscosity of the slurry.      2). Adjust the mixing process The stirring process is one of the key factors affecting the stability of the slurry. Optimizing the mixing process can improve the dispersion effect of solid particles in the slurry and reduce the settling speed. Specific measures include adjusting parameters such as the speed, linear speed, and mixing time of the mixer. An appropriate stirring process can evenly distribute solid particles in the slurry, thereby improving the stability of the slurry. 3). Adjust the amount of adhesive used Adhesive is an important component in maintaining the stability of the slurry. By adjusting the amount of binder, the viscosity and stability of the slurry can be optimized. While ensuring that the binder can fully encapsulate solid particles, avoid excessive addition that may cause the slurry to become too thick. Determining the optimal amount of binder through experiments can effectively solve the problem of large vis...

In recent years, due to the demand for new energy vehicles, consumer electronics, and energy storage industries, lithium-ion battery materials have grown rapidly. Lithium ion batteries are mainly composed of four key materials: positive electrode material, negative electrode material, separator, and electrolyte, with cost proportions of 45%, 15%, 18%, and 10%, respectively. 1. Positive electrode material The positive electrode material accounts for the highest proportion of the total cost of lithium-ion batteries, and its performance directly affects the core performance indicators of lithium-ion batteries, such as energy density, safety, and cycle life. The positive electrode material serves as a lithium-ion source and has a high electrode potential, resulting in a high open circuit voltage for the battery. Structure diagram of lithium-ion batteries: Data source: Public information. According to the classification of positive electrode materials, lithium-ion batteries can be divided into technical routes such as lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate(LiFePO4), and ternary materials. The current positive electrode materials mainly maintain a parallel pattern of lithium iron phosphate and ternary materials. The energy density improvement space of ternary material batteries is much greater than that of lithium iron phosphate cathode materials, while lithium iron phosphate batteries have the advantages of lower cost and relative safety. According to Baichuan Yingfu, China is expected to add a total of 1.625 million tons of lithium iron phosphate production capacity in 2023. From the perspective of market structure, the concentration of China's lithium iron phosphate industry is relatively high, with Hunan Yuneng and Defang Nanotechnology accounting for a relatively high proportion of production capacity, followed closely by manufacturers such as Changzhou Lithium Source, Hubei Wanrun, Rongtong High tech, Hunan Shenghua, Chongqing Terui, and Guoxuan High tech Power Energy. Ternary materials refer to positive electrode materials composed of nickel cobalt manganese or nickel cobalt aluminum, namely nickel cobalt manganese oxide (NCM) or nickel cobalt aluminum oxide (NCA). NCM ternary materials are the main ternary materials used by Chinese enterprises. Their advantages lie in energy density, and the higher the nickel content, the higher the specific capacity. They are widely used in new energy passenger vehicles. Due to its high cost, it is mainly used in mid to high end vehicle models. The future high nickel production has a large market space and is also a key direction for technology research and industrialization of various ternary cathode material manufacturers.

The Importance of Lithium Battery Separator Materials

The Importance of Lithium Battery Separator Materials

  Lithium batteries have completely changed every field from consumer electronics to electric vehicles, and separators play a crucial role in their performance and safety. Battery separator is one of the materials used in lithium batteries   The battery separator, anode electrode material, cathode electrode material, and electrolyte are the most important lithium-ion battery materials, accounting for approximately 4% of the total cost of lithium-ion battery materials. The lithium battery separator has a large number of tortuous and interconnected micropores, which can ensure the free passage of battery electrolyte ions and form a charging and discharging circuit. Its main function is to isolate the anode and cathode electrodes, preventing battery short circuits.   At the same time, ensure that lithium ions pass through the microporous channels normally during charging and discharging, ensuring the normal operation of the battery. The performance of the battery separator determines the key characteristics of lithium-ion batteries, such as internal resistance, capacity, cycling performance, and charge discharge current density.   At present, the commercialized lithium battery separators mainly include polyethylene (PE) separators, polypropylene (PP) separators, and PE and PP composite multilayer microporous membranes. PE battery separator has high strength and a wide processing range. PP membranes have high porosity, breathability, and mechanical properties. Ordinary 3C batteries mainly use single-layer PE separator or single-layer PP battery separator.   Power batteries generally use PE/PP double-layer battery separators, PP/PP double-layer separators, or PP/PE/PP three-layer separators. However, polyolefin membranes have very obvious drawbacks, such as thermal stability and insufficient wettability of electrolytes, which makes the coating and modification of polyolefin membranes a trend direction. Production process of battery separator   The production process of battery separators is mainly divided into two categories: wet method and dry method. The production process of lithium-ion battery separators includes raw material formula and rapid formula adjustment, microporous preparation technology, and independent design of complete equipment. Among them, microporous preparation technology is the core of lithium-ion battery separator preparation process, which can be divided into dry stretching and wet stretching according to the type of process.   Dry separators have high safety and low cost, and are often used in large lithium iron phosphate power batteries. Due to its thin thickness and high porosity, wet diaphragm has a higher uniformity of pore size and higher permeability. Compared with dry separators, it has certain advantages in mechanical performance, breathability, and physicochemical properties, so it is more widely used in ternary batteries that focus on energy density.   Membrane coating is the ...
