Practical, covering what real world battery engineers need to know to do their jobs, this is the first book that aligns with the many calculations and considerations that a battery engineer faces daily. Battery technologies play more and more important roles in our life. Not only phones or laptops but also electric vehicles use Li-ion batteries. Together with the growth of the battery market, more battery engineering jobs are demanded worldwide. To be successful in the industry, a wide variety of knowledge is required, ranging from electrochemistry to material science, physical chemistry, machine learning, etc. Covering the basics (battery design, impedance, charging, manufacturing, etc.) and the many questions on alternatives (supercaps, energy harvesting, fuel cells, etc.), and new frontiers (better algorithms, new chemistries like Si anode and Li metal anode, and new AI/ML/DL possibilities) it will help you obtain practical knowledge with intuitive explanations; real battery problem sets and answers. A great resource for a battery engineer to expand their knowledge to broader areas and anyone, including college students
