With the continuous progress of technology, the development of positive electrode materials is mainly focused on improving energy density, improving safety performance and extending battery life. For example, high-nickel ternary cathode materials increase energy density by increasing nickel content while reducing cobalt content to reduce cost and environmental impact. However, this also leads to the deterioration of electrode structural stability and thermal stability, and the reduction of battery cycle stability. Further material innovations and process improvements are needed to ensure their safety and long-term reliability. The innovation of cathode materials is crucial to the development of the lithium-ion battery industry, which is not only related to the improvement of battery performance, but also affects the market competitiveness and sustainable development of the entire industry. With the continuous emergence of new materials and new technologies, the performance of lithium-ion batteries will continue to be optimized and improved. The development of the lithium-ion battery industry has been driven by the dual advancement of material technology and patented technological innovation. In recent years, with the rapid development of the new energy vehicle market, the demand for lithium-ion battery technology has entered a new peak, and major battery manufacturing enterprises have increased research and development investment, competing to take the lead in battery performance, safety, cost and patented technology. Patent data show that patent activity for batteries and other power storage technologies grew at an average annual rate of 14 percent between 2005 and 2018, four times the average for all technology fields. This growth is mainly driven by advances in rechargeable lithium-ion battery technology, especially in consumer electronics and new energy vehicles. The demand for electric mobility has prompted the development of high-performance lithium-ion technology aimed at improving battery energy density, service life, charging and discharging speed, and low temperature performance. In addition, in order to better integrate renewable energy sources such as wind and solar into the power network, it has also promoted the progress of energy storage battery technology.

The Critical Role of Electrolytes in Battery Performance 1. Introduction 2. The main components of battery electrolytes typically include 3. Key functions of battery electrolytes 4. When selecting a battery electrolyte, several factors need to be considered 1. Introduction Electrolyte refers to a substance that contains free ions and is able to conduct electricity when dissolved in a solvent, such as water or an organic solvent. In the context of batteries, an electrolyte is a component that enables the movement of ions between the anode and the cathode during the charging and discharging cycles. It physically separates the electrodes while allowing the transfer of ions, thus enabling the electrochemical reactions that power the battery. Electrolytes can be liquid, solid, or gel-like, depending on the specific application and requirements of the battery. Battery electrolytes play a crucial role in the performance and efficiency of batteries. They facilitate the movement of ions between the electrodes during charging and discharging cycles. The composition of battery electrolytes varies depending on the type of battery, but generally, they consist of several key components. 2.The main components of battery electrolytes typically include 1).Solvents: Solvents are used to dissolve the electrolyte salts and create a conductive solution. Common solvents include organic carbonates such as propylene carbonate (PC), ethylene carbonate (EC), dimethyl carbonate (DMC), and ethyl methyl carbonate (EMC). These solvents have high solubility for electrolyte salts and excellent electrochemical stability. 2).Electrolyte Salts: Electrolyte salts provide the ions that participate in the electrochemical reactions in the battery. For lithium-ion batteries, lithium salts such as lithium hexafluorophosphate (LiPF6) are commonly used. Other lithium salts like lithium perchlorate (LiClO4) and lithium tetrafluoroborate (LiBF4) may also be employed, depending on the specific requirements of the battery. 3).Additives: Additives are incorporated into the electrolyte to enhance its performance and safety. These additives can serve various functions, such as improving the wettability of the electrodes, increasing the ionic conductivity, preventing electrolyte decomposition, and improving the battery's thermal stability. Common additives include vinylene carbonate (VC), fluoroethylene carbonate (FEC), and various ionic liquids. The composition of the battery electrolyte is tailored to meet the specific requirements of the battery, such as voltage range, energy density, cycle life, and safety. The choice of solvent, electrolyte salt, and additives depends on factors like the battery chemistry, operating conditions, and desired performance characteristics. In summary, battery electrolytes consist of solvents, electrolyte salts, and additives that work together to facilitate ion transport and enhance the performance and safety of the battery. 3.Key functions of battery electr...

With the increasing attention of the world to clean energy and sustainable development, lithium batteries as an important source of energy for electric vehicles, smart phones and other electronic products, its manufacturing industry is ushering in a new round of change. Recently, the Ministry of Industry and Information Technology issued the "Lithium battery industry Specification Conditions (2024)" (draft for comment) and the "Lithium battery industry Specification Announcement Management Measures (2024)" (draft for comment) have attracted wide attention from the industry. It is reported that the two drafts are aimed at further strengthening the management of the lithium battery industry, guiding enterprises to reduce manufacturing projects that simply expand production capacity, while strengthening technological innovation, improving product quality, and reducing production costs. The introduction of this policy marks that the lithium battery manufacturing industry is developing in a more standardized, efficient and green direction. According to the draft, lithium battery enterprises should have the independent production, sales and service capabilities of lithium battery industry-related products, and the annual cost for research and development and process improvement is not less than 3% of the main business income. This regulation encourages enterprises to increase investment in technological innovation and promote technological progress in the industry and the improvement of product performance. It is worth mentioning that the new specification puts forward higher requirements for performance indicators such as energy density, power density and cycle life of lithium batteries. Among them, the energy density of the energy type single battery using ternary materials (lithium nickel-cobalt manganate) needs to reach 230Wh/kg or more, and the energy density of the battery pack needs to reach 165Wh/kg or more. The energy density of the energy type single battery using other materials such as lithium iron phosphate needs to reach 165Wh/kg or more, and the energy density of the battery pack needs to reach 120Wh/kg or more. The improvement of these indicators will promote the progress of lithium battery technology and meet the market demand for higher performance batteries. In addition to technological innovation and product performance enhancement, the new specification also strengthens the requirements for production safety and environmental protection. The draft encourages enterprises to create green factories and adds regulations on work safety, environmental protection, energy conservation and emission reduction. This initiative will help promote the sustainable development of the lithium battery manufacturing industry and reduce the impact on the environment.
