Who has mastered the solid-state battery technology, who has the new energy vehicle market!
The development of all-solid-state batteries began in the 1970s. Only later, with the technological innovation and large-scale commercial use of lithium-ion batteries in the early 2000s, the industry's attention to all-solid-state batteries has declined. Thirty years to the east, thirty years to the west, a new round of battery innovation cycle may be opened in 2030.Compared with liquid batteries, the core change of solid-state batteries is the introduction of solid electrolytes. According to the material type of solid electrolyte, the current solid state battery mainly includes oxides, sulfides, polymers and halides and other technical routes, and each route has its own advantages and disadvantages. For example, the oxide has high safety, but its easy brittleness leads to its complicated preparation process; Sulfide has high ionic conductivity, but the air stability is poor and H2S toxic gas is formed, and the cost is high. The polymer is relatively soft, the solid contact is the best, but the conductivity is low; However, halides are still mainly in the laboratory research stage.The whole industry placed the hope of the "next generation battery" on solid-state batteries, and even believed that this is the terminator of liquid lithium batteries, mainly due to the perfect properties of solid-state batteries.First, high security.Secondly, the energy density of all-solid-state batteries should also exceed that of liquid batteries, and the theoretical upper limit can reach 500 Wh/kg.Thirdly,Increased energy density means increased endurance.Lastly, the ion conduction mode of the liquid battery needs to go through solvation, desolvation and other processes, and the charging power is therefore limited.However, good all have a price, so far no manufacturer can produce solid-state batteries on a large scale, which actually reflects the difficulty of high.Since solid-state batteries still have so many challenges, why are so many companies insisting on developing solid-state batteries?1.the product characteristics of solid-state batteries can solve the safety and mileage anxiety of current new energy vehicle usersDue to the use of non-flammable, high and low temperature non-vaporization and non-solidification of solid electrolyte, solid-state batteries show strong high temperature safety, and maintain good low temperature characteristics to avoid low temperature battery life greatly reduced; In addition, solid-state batteries, due to their higher voltage window, can be further adapted to high-capacity positive and negative materials, such as lithium-rich manganese anode, silicon-based negative electrode and lithium metal negative electrode, so as to achieve higher energy density and increase the battery life under the same power.2.In the context of global competition for new energy vehicles, the competition for solid-state batteries is being staged around the worldIn the face of the industrial advantages formed by China in the development of global new energy vehicles, especially in the field of power batteries, which makes countries in Europe and the United States that need to transition to new energy urgently need to find new solutions, so the research and development of solid-state batteries has risen to become the national strategy of major countries in the world. For example, Japan is making national efforts to develop sulfide solid-state batteries, and strive to achieve 450Wh/L and 6C (@25 ° C) by 2027; The EU has also built a complete battery system from policy, innovation, and business, and plans to achieve polymer or composite solid-state batteries to break through 400-500Wh/kg and 800-1000+Wh/L during 2027-2030. The United States DOE plans to develop a solid-state battery in 2030 in 2021, with a production cost of less than $60 /kWh and an energy density of 500Wh/kg; Based on its K-Battery strategy, South Korea has also explicitly invested 40.6 trillion won to promote the commercial use of 400Wh/kg solid-state batteries in 2025-2028 and the loading of vehicles in 2030; China also set up the solid-state battery industry innovation consortium and the all-solid-state battery industry-university-research collaborative innovation platform in this half year to accelerate the breakthrough of (all) solid-state batteries and maintain the leading edge.

What is the Polymer Binder for Lithium-Ion Battery?
The Importance of the Polymer Binder for Lithium-Ion BatteryLithium-ion batteries have revolutionized the world of portable electronics and are increasingly being used in electric vehicles and renewable energy storage systems. One critical component of these batteries is the polymer binder, which plays a crucial role in their overall performance and durability. In this article, we will delve into the world of polymer binders for lithium-ion batteries and explore their importance and functions in detail.Understanding Polymer BindersPolymer binders are a vital component of the electrode materials in lithium-ion batteries. They are responsible for holding the active materials, such as lithium compounds, together in a stable structure. These binders are essentially polymers, which are large molecules consisting of repeating subunits. They are chosen for their ability to form a strong bond with the active materials and provide mechanical stability to the electrode.Enhancing Electrode AdhesionOne of the key functions of the polymer binder is to improve the adhesion between the active materials and the current collector. The active materials in a lithium-ion battery electrode are typically in the form of powders, which can easily detach and degrade during cycling. The polymer binder acts as a glue, binding the active materials to the current collector and preventing their detachment. This enhances the overall electrode stability and prolongs the battery's lifespan.Facilitating Ion TransportIn addition to improving electrode adhesion, the polymer binder also plays a crucial role in facilitating the transport of lithium ions within the battery. Lithium ions are the carriers of charge in lithium-ion batteries, and their efficient movement between the electrodes is essential for the battery's performance. The polymer binder helps create a network of interconnected pathways within the electrode, allowing for rapid and unhindered ion transport. This results in higher battery efficiency and faster charging/discharging rates.Ensuring Electrode FlexibilityFlexibility is another important characteristic of a polymer binder in lithium-ion batteries. As the battery undergoes repeated charge-discharge cycles, the electrode materials expand and contract. A rigid binder would restrict these movements, leading to mechanical stress and premature electrode degradation. Polymer binders with appropriate flexibility can accommodate the volume changes without compromising the structural integrity of the electrode, ensuring the long-term stability and performance of the battery.Preventing Electrode SwellingDuring battery operation, the active materials in the electrode can undergo a volume change, leading to electrode swelling. This swelling phenomenon can cause mechanical stress on the electrode and result in capacity loss or even battery failure. Polymer binders with good swelling resistance can effectively mitigate this issue by providing mechanical support and preventing excessive expansion of the electrode. This enhances the overall safety and reliability of lithium-ion batteries.Enhancing Thermal StabilityThermal stability is a critical aspect of lithium-ion batteries, especially in high-performance applications. Polymer binders with high thermal stability can withstand the elevated temperatures that can be generated during battery operation. They prevent the binder from decomposing or melting, which could lead to the loss of electrode integrity and reduced battery performance. Choosing a polymer binder with excellent thermal stability is therefore crucial to ensure the safe and reliable operation of lithium-ion batteries.Impact on Battery Energy DensityThe selection of the polymer binder can also significantly impact the energy density of a lithium-ion battery. Energy density refers to the amount of energy that can be stored within a given volume or weight of the battery. By choosing a polymer binder with low weight and high compatibility with the active materials, the overall weight of the battery can be reduced, resulting in higher energy density. This is particularly important for applications where lightweight and compact batteries are desired, such as electric vehicles.Considerations for Binder SelectionWhen selecting a polymer binder for lithium-ion batteries, several factors need to be considered. These include the binder's mechanical strength, adhesion properties, ionic conductivity, thermal stability, and compatibility with other battery components. Additionally, considerations such as cost, availability, and environmental impact should also be taken into account. A thorough understanding of these factors is crucial to choose the most suitable polymer binder for a specific battery application.Future Developments and InnovationsThe field of polymer binders for lithium-ion batteries is continuously evolving, with ongoing research and development aimed at improving battery performance and durability. Scientists and engineers are exploring new polymer materials and binder formulations to enhance adhesion, ionic conductivity, and thermal stability. Additionally, the use of advanced manufacturing techniques, such as 3D printing, is being investigated to create customized binder structures that optimize battery performance. These innovations are expected to drive the next generation of lithium-ion batteries with even higher energy density, longer lifespan, and improved safety.Quote Inquiry

Cutting-edge technology in new energy vehicles: Conductive carbon black
Conductive carbon black is a type of conductive agent and an important auxiliary material in lithium batteries.Compared to other conductive agents, conductive carbon black has better overall performance and is currently the mainstream conductive agent. Benefiting from the continuous growth in demand for downstream new energy vehicles, we expect the global market space for conductive carbon black to be around 7.6 billion yuan by 2027. In terms of production process, the main barrier for conductive carbon black lies in the design of reaction furnace equipment. In terms of production cost, the main cost components of this product include raw materials such as coal tar. In terms of market landscape, this product has mainly relied on imports in the past, but is currently accelerating domestic substitution. Domestic companies mainly include Black Cat Corporation, Jiaozuo Hexiong, Yongdong Corporation, and Wuxi Dongheng. Looking at future trends, conductive carbon black is suitable for the trend of composite conductive agents. Conductive carbon black is the mainstream lithium battery conductive agent, with core technology creating barriers Conductive agents are important auxiliary materials for improving the conductivity of lithium batteries, which can compensate for the poor conductivity of positive electrode materials and maintain the conductivity performance of negative electrode materials after repeated expansion and contraction. Conductive carbon black performs well when considering factors such as the degree of improvement in electrode conductivity, slurry dispersion performance, formulation dosage, and cost. According to GGII data, conductive carbon black accounted for 65% of China's power battery conductive agents in 2022. The performance of conductive carbon black is mainly determined by its structural characteristics, specific surface area, and magnetic impurity content. The performance requirements for lithium-grade conductive carbon black are higher than for ordinary carbon black, and the product performance can be classified from low to high as acetylene black, SP, and Ketjen black. The reaction furnace is an important reaction equipment and a core barrier for the production of conductive carbon black, with components such as the oil nozzle in the furnace head being crucial for accuracy. Localization and cost reduction are the trend, with potential for small and beautiful new energy tracks In terms of cost composition, raw materials such as coal tar account for approximately 80% of the cost of conductive carbon black. The price of imported conductive carbon black has long been high, with shipping costs accounting for a certain proportion.Domestic substitution can eliminate shipping costs, while domestic raw material costs are lower than overseas costs, making it cost-effective. Assuming that the proportions of conductive carbon black added to ternary positive electrode materials, lithium iron phosphate and other positive electrode materials, and negative electrode materials are 2%, 3%, and 1% respectively, and the penetration rates of conductive carbon black from 2023 to 2027 are 56%, 54%, 52%, 51%, and 50%, the global market demand for conductive carbon black from 2023 to 2027 is estimated to be 48,000 tons, 66,000 tons, 89,000 tons, 118,000 tons, and 152,000 tons, corresponding to market spaces of 3.14 billion yuan, 3.94 billion yuan, 4.87 billion yuan, 6.15 billion yuan, and 7.60 billion yuan. Domestic substitution is underway, with efforts to promote expansion In the past, due to the dispersed scale of domestic carbon black companies and their focus on the tire market, as well as insufficient core research and development technology for reaction furnaces, domestic conductive carbon black was almost entirely dependent on imports. Major companies included France's Orion Stone, the United States' Cabot Corporation, Japan's Lion King, and Japan's Denka Corporation. With the accelerated penetration of downstream new energy vehicles and the significant increase in demand for lithium batteries, overseas supply of conductive carbon black has been unable to meet demand and prices have been high. Domestic companies have begun to initiate domestic production, gradually achieving technological breakthroughs. Major companies include Black Cat Corporation, Jiaozuo Hexiong, Yongdong Corporation, and Wuxi Dongheng.Risk warning: Lower-than-expected sales of downstream new energy vehicles, slower-than-expected industrialization progress, technological innovations, and the mention of companies in the industry chain do not represent coverage or investment recommendations for the company.
