Lithium-ion battery’s life cycle: safety risks and risk management at workplaces


The problem addressed

Lithium-ion (Li-ion) batteries are widely used in vehicle industry. The use of Li-ion batteries as an energy source of vehicles reduces harmful emissions compared to combustion engines enabling the use of such vehicles also indoors. Thus, the different applications utilizing Li-ion batteries are considered as part of sustainable development of energy storage systems.

A solid regulatory framework for the environmental aspects already exists but the occupational safety aspects of the production chain are less explicit. Still, handling of and operating with Li-ion batteries poses several occupational risks, especially related to work and chemical safety. Therefore, it would be highly beneficial to recognize the occupational safety risks in the overall value chain of Li-ion battery, and to provide suitable risk control methods.

Research questions

The research hypothesis proposes that by studying safety we can point the issues that need to
be enhanced in order to promote occupational safety and working environment.
Research questions (RQ) focus on occupational safety, exposure and life-cycle assessment
through Li-ion batteries’ value chain.
  • RQ1: Which are current practices throughout the value chain to determine the safety, sustainability and management measures of Li-ion batteries?
  • RQ2: Which are the impacts of a LI-ion battery identified by performing a life cycle assessment on an example case?
  • RQ3: What are critical occupational risks (including accidents) and how are they managed in Li-ion battery value chain?

Keywords: LCA

Scientific disciplines: chemistry/chemical engineering

Expected outputs

The results of the study are expected to include:
  • Identification of most significant occupational safety risks for the most relevant supply chains and batteries, and identification of key supply chains and materials, regarding flow of priority materials and their hazard.
  • Analysis of main hazards for human health during the production, utilization and end of life of Li-ion batteries, also in accidental events: occupational safety (mainly through Risk Assessment) and potential damage to human health and environment over the life cycle of batteries (mainly through Life Cycle Assessment).
  • Analysis of the main environmental impacts associated to emissions of hazardous materials, focusing on the exemplary case.
  • Providing practical risk control methods to develop and improve work environments and the safety and well-being at work.
  • Generating specific guidance on the occupational safety issues to be provided to the industry and other stakeholders.
