The development of battery technology has revolutionized various industries, ranging from consumer electronics to electric vehicles. One critical aspect of battery production is the electrode roller pressing process, which plays a crucial role in determining battery performance. This article aims to highlight the significance of battery electrode roller pressing and its impact on battery performance. Battery Electrode Roller Pressing: Battery electrode roller pressing refers to the process of applying pressure to the electrode materials, effectively compressing them together to form a dense and uniform structure. The primary purpose of this technique is to enhance the performance of the battery by improving the electrode's adhesion, uniformity, and overall conductivity.

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...

  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 ...

1. Layered oxide cathode material Layered oxides  in sodium ion batteries material have inherent cost advantages, not only because these materials can learn from the highly mature solid-state or co precipitation methods commonly used in lithium-ion batteries to achieve low-cost large-scale production, but also because they have a rich selection of active elements. The chemical formula of layered oxide positive electrode materials for sodium ion batteries can be expressed as NaxTMO2 (x ≤ 1, where TM is one or more of the 3D transition metals such as Ni, Mn, Fe, Co, Cu, etc.). By studying the coordination environment of sodium ions and the stacking mode of oxygen, layered oxides can be classified into the following categories: 2. Polyanionic positive electrode material Polyanion positive electrodes have better thermal stability and thus better safety, but their biggest drawback is their low electronic conductivity, which prevents them from charging and discharging under high currents, and their specific capacity is low. Therefore, its conductivity is often improved by coating and doping, thereby improving its electrochemical performance. The general formula of polyanionic compounds can be expressed as NaxMy [(XOm) n –] z, where M is an electrically active transition metal and X is a non-metallic element such as P, S, Si, etc. Among them, sodium vanadium phosphate [Na3V2 (PO4) 3] material with NASCON (Na Super ionic conductor) structure has high voltage and specific capacity. 1.3 Prussian Blue Cathode Materials The Prussian blue cathode material has a perovskite like structure and a face centered cubic structure.

The electrolyte is in a harsh living environment. It faces the strong reducibility of the negative electrode and the strong oxidation of the positive electrode. Adding flame retardants to make the electrolyte non combustible and reduce its flammability is an effective way to improve the safety of batteries. However, this approach has limited improvement in battery safety, especially when the capacity of commercial batteries exceeds 100 ampere hours, and flame retardants cannot stop them,Because the combustion of batteries is contributed by combustible gases.   During the process of thermal runaway, there are two factors that lead to thermal runaway safety. One contributes to combustible gases, and the other contributes to oxygen and temperature.   The first is combustible gas: Flame retardants can only ensure that the electrolyte is not combustible in a liquid state, but the negative electrode reacts with the electrolyte to produce a large amount of reducing gas, which is flammable and provides a foundation for combustion.   The second is that the exothermic reaction of the battery body provides high temperature. The solid body generates oxygen when heated at around 200 degrees Celsius, and the solid part of the battery provides a high-temperature environment; Combustible gases themselves can burn, and the solid part provides a temperature, which inevitably leads to combustion.   By changing the reaction path between the electrolyte and the negative electrode, reducing the types and quantities of reducing gases, the safety of the battery can be improved from this perspective. In the thermal runaway test, there are three temperatures that represent different physical meanings:   T1 represents the battery entering the self heating stage, where the negative electrode reacts with the electrolyte to form a reducing gas. The reducing gas flows to the positive electrode, attacking the lattice of the positive electrode, causing a phase transition and oxygen release. Oxygen reacts with EC in the electrolyte, causing a temperature increase. Form T2, which is the triggering temperature for thermal runaway. The time spent in the temperature range of T1 and T2 is relatively long, and work can be done from passive protection. The positive and negative poles react violently, forming the highest temperature T3.   Regulation method: 1. Electric regulation: discharge control of the battery. Because the reaction is for electrons, through discharge, electrons are released, and if electrons are not released, reducing gases cannot be generated. 2. Gas regulation: Use intelligent exhaust valves to forcibly exhaust, avoiding crosstalk, accumulation, and combustion. 3. Cooling: Reduce reaction speed. 4. Poisoning agent: Release a poison agent on the composite collector to absorb the gas. 5. Reduce or block the path of combustible gas production. For example, EC free, or reducing the amount of EC electrolyte, such as perfluorinated electrolyt...

The working principle of Sodium-ion battery is the same as that of lithium ion battery, that is, during the charging and discharging process, lithium ion is inserted/de inserted and inserted/de inserted back and forth between the positive and negative electrodes, which is also called "rocking chair battery". Lithium ion batteries mainly rely on the movement of lithium ions between the positive and negative electrodes, using embedded lithium compounds as the positive electrode material. The working principle of Sodium-ion battery is: during charging, Na+is disembedded from the positive electrode and embedded into the negative electrode through battery electrolyte; When discharging, the opposite is true. Sodium battery, with its abundant resource reserves and significant advantages in low-temperature performance, rate performance, and cost compared to lithium battery, gradually demonstrates the potential for specific scenarios. AOTELEC provides sodium ion battery materials.
