The rapid development of new energy technology has made prismatic cells the powerhouse of the new energy era, owing to their outstanding performance and wide range of applications. So, what exactly are prismatic cells, and what unique advantages and uses do they offer? 1.Overview of Prismatic Cells Prismatic cells, as the name suggests, are lithium cells with prismatic alloy casing. Domestic power battery manufacturers mainly use prismatic cells with higher energy density because the structure of square cells is simpler compared to cylindrical ones. Unlike cylindrical cells that use high-strength stainless steel for casings and safety valves to prevent explosions, the overall weight of attachments in square cells is lighter. Prismatic cells have higher structural strength, better tolerance to mechanical loads, lower internal resistance, longer lifespan, minimal decrease in energy density after assembly, and higher space utilization. 2.Advantages of Prismatic Cells High Energy Density: Prismatic cells have a much higher energy density than traditional cells, meaning they can store more energy in smaller volumes and weights. This characteristic makes them widely applicable in fields like aerospace, mobile communications, etc. Long Lifespan: Prismatic cells have a long cycle life, enduring multiple charge-discharge cycles without affecting their performance. This makes them widely applicable and promising in areas such as electric vehicles, energy storage systems, etc. High Safety: Prismatic cells use prismaticalloy casings, which have higher resistance to impact and compression. Additionally, their internal structure is designed rationally to effectively prevent safety hazards like short circuits, overcharging, and over-discharging. [Theoretically, there isn’t a strong correlation between prismaticshell materials and cell safety. 3.Surface Treatment Processes for Prismatic Cells Currently, prismatic alloy casings are the most widely used materials for power cells housings. Existing prismatic shells are typically formed by stamping prismatic sheets to create shells, which are then cleaned for subsequent processes. However, surface scratches caused during stamping or handling can
The global automotive landscape is experiencing a significant transformation with the increasing growth of electric vehicles (EVs). In 2023, electric vehicles represented approximately one-quarter of all new cars sold worldwide. Remarkably, in Norway, over 90% of new car sales were electric, while in China, the figure approached 40%. This surge is fueled by advancements in EV technology, heightened consumer awareness, and robust governmental policies aimed at curbing carbon emissions. At the core of an electric vehicle is its battery, a vital component that determines the vehicle’s range, efficiency, and performance. Given this critical role, manufacturers are intensively focusing on enhancing their car battery production capabilities. The drive for improvement is not solely about increasing battery power or longevity but also about optimizing the production process through cutting-edge automated assembly lines. These technological enhancements are essential as they significantly influence the quality and cost-effectiveness of the batteries, which in turn affects the EV’s competitiveness in the market. To meet these challenges, various innovative assembly line technologies have been developed, each designed to address the specific needs of modern battery manufacturing. This article explores the top three types of car batteries automated assembly lines that are defining the future of battery manufacturing for electric vehicles. Mainstream Battery Materials in Electric Vehicles As the electric vehicle industry evolves, so too do the materials that power its core— the batteries. These two types of car batteries that are the most prevalent materials used in EVs are Lithium Iron Phosphate (LFP) and Lithium-ion ternary batteries. Each offers distinct advantages that cater to different automotive needs. 1. LFP Battery Lithium Iron Phosphate (LFP) batteries are highly valued for their exceptional safety and longevity. Known for its strong thermal and chemical stability, this type of car battery is less prone to overheating, thereby extending its operational life
Scaling up battery production using conventional battery assembly methods has become increasingly challenging due to the surging demand for battery-powered products. It would be hard to meet the precise cell alignment, consistent quality and production levels, on-time completion, and rising competition are some of the biggest challenges. Additionally, factors such as the necessity to invest in logistic infrastructure and the challenge of meeting stringent environmental and safety regulations add another layer of complexity to boosting battery manufacturing and assembly methods. These challenges highlight the need for upgrading better battery assembly solutions to improve efficiency and drive industry progress in the future. And this is where smart manufacturing comes into play. What is Smart Manufacturing? Smart manufacturing in battery assembly involves integrating advanced automated technologies to optimize production, ensure quality control, and enhance safety. The robotic system employed in the smart manufacturing techniques can significantly reduce downtime, minimize errors, and offer quality control on the battery pack assembly line. What are the Principles of Smart Manufacturing in Battery Assembly? Understanding the principles of smart manufacturing will help you understand why more and more businesses are transitioning to this next-generation manufacturing technique. Smart manufacturing is a sophisticated system that accelerates the fabrication and assembly process by employing computing automation at every step. It creates a digitally connected manufacturing environment where the production processes are supervised using data analytics. Capable of making autonomous decisions, the smart manufacturing system has revolutionized both the manufacturing sector and the economy. Talking specifically, here is a rapid overview of all the foundational principles supporting this groundbreaking approach. The smart production process is based on a network of communication involving battery assembly machines, devices, sensors, and people. This connectivity facilitates live monitoring and management of the battery manufacturing process, grasping a more comprehensive status during the manufacturing compared
