Major Mistakes in Lithium Battery Energy Storage Model

The penetration of the lithium-ion battery energy storage system (LIBESS) into the power system environment occurs at a colossal rate worldwide. This is mainly because it is considered as one of the major tools to decarbonize, digitalize, and democratize the electricity grid.

The LIBRA model represents major systemic feedback loops and delays across the supply chain. This report provides a complete documentation for the LIBRA model, including model assumptions, data, scenario analysis results, and sensitivity analysis of the model’s input space.

Lithium-ion battery safety is one of the main reasons restricting the development of new energy vehicles and large-scale energy storage applications [5]. In recent years, fires and spontaneous combustion incidents of the lithium-ion battery have occurred frequently, pushing the issue of energy storage risks into the limelight [6] .

To reach the hundred terawatt-hour scale LIB storage, it is argued that the key challenges are fire safety and recycling, instead of capital cost, battery cycle life, or mining/manufacturing challenges. A short overview of the ongoing innovations in these two directions is provided.

Lead-acid batteries, a precipitation–dissolution system, have been for long time the dominant technology for large-scale rechargeable batteries. However, their heavy weight, low energy and power densities, low reliability, and heavy ecological impact have prompted the development of novel battery technologies.
