Drawing on more than 30 years of experience in the electric vehicle and battery sector, BatteryDesign.net has introduced a comprehensive technical guide designed for all stakeholders in the battery industry. Published under the title “Battery A to Z” the up-to-date resource covers topics ranging from fundamental physical principles to advanced manufacturing processes. Intended as a central knowledge hub for battery designers, researchers, and manufacturers, the platform provides free benchmarking data and technical articles aimed at accelerating the electrification transition. Beyond explaining technical terminology, the guide also outlines a strategic roadmap for the future of batteries through the lenses of sustainability and the circular economy.
Created by experts with extensive backgrounds in research and concept design at major automotive OEMs, the initiative seeks to reduce misinformation and fragmentation within the battery sector. The platform details the transition from traditional 12V lead-acid systems to modern lithium iron phosphate (LFP) chemistries and explains the differences between 400V and 800V architectures using technical data. It also highlights the advantages of cylindrical cell formats such as 18650 and 21700, alongside next-generation 46 mm diameter cells. In addition, the guide explores advanced concepts including 3D electrodes and reference electrodes used in battery development.
Sustainability is presented as one of the most critical aspects of battery technology. The guide emphasizes the “4R” principle—Repair, Remanufacture, Repurpose, and Recycle—demonstrating the importance of life cycle analysis for batteries. It discusses the significance of CO₂ emissions and toxic waste management throughout the battery’s journey from cradle to grave, while also highlighting the economic value of intermediate recycling products such as “black mass,” which contains valuable metals. Emerging technologies, including all-solid-state batteries (ASSB) and calcium-based chemistries that rely on more abundant materials than lithium, are also featured among the platform’s future-oriented topics.
Battery Management Systems (BMS) are described as the brain of a battery pack, with detailed explanations of both hardware and software algorithms. The guide outlines how BMS continuously monitors voltage, temperature, and current values while calculating parameters such as State of Charge (SoC), State of Health (SoH), and State of Function (SoF). It also examines passive and active cell balancing methods and their impact on battery lifespan and performance. These systems protect batteries against risks such as overcharging, excessive current, and overheating, maximizing both safety and efficiency.
Battery manufacturing processes are divided into three main stages: electrode production, cell assembly, and finishing operations. Processes such as mixing, coating, drying, and calendaring are identified as key factors influencing battery quality. Mechanical aspects including cell expansion, tab design, and thermal management are also analyzed in terms of their effects on cycle life. Furthermore, the platform explores next-generation integration concepts such as Cell-to-Chassis (C2C) and Cell-to-Body (C2B), demonstrating how battery packs are becoming increasingly integrated into vehicle structures to enhance overall energy density.
