The Safety Challenges and Strategies of Using Lithium-Ion Batteries
Description
Comprehensive reference detailing the manufacturing, storage, transportation, safety, and regulations of Li-Ion batteries
The Safety Challenges and Strategies of Using Lithium-Ion Batteries presents a comprehensive overview of the safety issues related to lithium-ion batteries. After an introduction explaining the basics of lithium-ion battery technology and the various components used throughout the manufacturing process, the book delves into the design and process of failure models and mechanisms including cell assembly, formation, and electrode preparation processes, discusses the compliance, regulations, and standards of lithium-ion battery transportation, and reviews how environmental factors such as temperature, humidity, and atmospheric pressure can affect the durability, performance, and safety of batteries.
The reader is presented with the range of companies that are producing batteries, the various lithium-ion chemistries being implemented in batteries by these companies, and which chemistries are being used for which applications. Next, the various defects in design and manufacturing that can affect the propensity for fires are presented along with best practices. This section is followed by an overview of the qualification tests, quality assurance methods, and standards needed to ensure safe design.
The Safety Challenges and Strategies of Using Lithium-Ion Batteries includes information on:
- Types of batteries and the trade-off between energy density and safety risks
- Thermal runaway and mitigation strategies such as flame retardants and venting mechanisms
- The reuse, repurposing, and disposal of batteries and how new regulations in the European Union concerning the ability to replace batteries and the right to repair will affect safety risks
- The battery supply chain in the consumer, industrial, electric vehicle, and renewable energy sectors
- Data transparency challenges between manufacturers and end-users/system designers
Written by a team of experts, The Safety Challenges and Strategies of Using Lithium-Ion Batteries is essential reading for professionals working in a wide range of industries including batteries, EV, and energy storage.
