1.Research background and concept of fast charging battery With the introduction of the “double carbon” goal, a low-carbon trend in global energy and industrial development has emerged. Consequently, utilizing clean energy to power vehicles holds great significance in reducing CO2 emissions and achieving carbon neutrality. Electric vehicles powered by lithium-ion batteries have increasingly drawn attention due to their high energy density, long cycle life, low cost, and minimal environmental pollution. Nevertheless, despite projections that the global electric vehicle fleet will hit 230 million by 2030, both market penetration and consumer acceptance remain relatively low at present. One of the important reasons is mileage anxiety. Therefore, fast charging lithium-ion batteries have become

1.Research background and concept of wide temperature range battery   Since the 1970s. Lithium-ion batteries have attracted wide attention after researchers found the lithium storage performance of layered oxides and sulfides. Multi-application scenarios not only reflect the advantages of lithium batteries, but also the driving force of their development. As shown in Figure 1, lithium batteries only need to meet the operating temperature of 15~35 °C in applications such as electric vehicles and portable electronic devices. However, in some special application scenarios, lithium batteries are required to break through this temperature range. For example, the oil industry needs lithium batteries to adapt to a working environment of about 80 °C,

1.Research background and concept of pre lithiation technology With the advancement of technology and the development of society, energy consumption and environmental pollution problems are becoming more and more serious, which has led to the pursuit of efficient and environmentally friendly energy storage solutions. Lithium-ion battery  is one of the most mainstream energy storage devices, and its performance improvement has become a research hotspot. However, traditional methods of enhancing electrode material performance and developing new electrolyte systems have faced limitations. During battery cycling, the irreversible loss of lithium ions severely impacts the energy density and cycle life of the battery. Previous methods for improving battery performance have struggled to meet

1.The concept and research background of solid-state lithium battery Since the 1990s, lithium-ion batteries have developed into the most mature and widely used battery technology route. With the increasing requirements of the market for battery energy density, safety, and economy, ‘solid-state batteries‘ that use solid electrodes and solid electrolytes and have higher energy density and safety have emerged. Traditional lithium-ion batteries include four major components: positive electrode, negative electrode, electrolyte and separator. Solid-state batteries replace the electrolyte with solid electrolyte. The key difference between solid-state batteries and traditional lithium-ion batteries is that the electrolyte changes from liquid to solid, taking into account safety, high energy density and other properties. Solid

1. Overview of cathode materials of lithium-ion batteries As the global transition to renewable energy and electric mobility accelerates, the spotlight has turned to the core component of the energy revolution: the Lithium-ion Battery (LIB). While a battery consists of several parts, the cathode material is widely considered the “heart” of the system. It dictates nearly 40% of the total cell cost and is the primary factor determining a battery’s energy density, safety, and lifespan. Why the Cathode is the “Heart” of the Battery？ In a lithium-ion cell, the cathode acts as the positive electrode. Its primary role is to serve as a host for lithium ions. Energy Capacity: The

Overview of anode materials of lithium-ion batteries In 1989, SONY company found that petroleum coke carbon materials could be used to replace metal lithium to make secondary batteries, which really opened the prelude to the large-scale application of lithium-ion batteries. In the next 30 years, three generations of products such as carbon, lithium titanate and silicon-based materials have been used as anode materials. This article will briefly introduce various lithium-ion battery anode materials according to the structural classification of anode materials. Characteristics of ideal anode materials The ideal anode material should have the following characteristics: 1.Low lithium insertion potential: To ensure a higher output voltage (the potential of the lithium
