The transition to decarbonized vitality is anticipated to require extra lithium and different battery supplies to assist grid-level vitality storage, electrical automobiles, and cellular gadgets. NREL has developed a software program device, the Lithium-Ion Battery Useful resource Evaluation Mannequin (LIBRA), to know the dynamics of a sustainable provide chain of those supplies.
Ongoing analysis at NREL explains the want for provide chain stability for a clear vitality future. The LIBRA mannequin helps researchers higher perceive the numerous elements affecting the availability chain of lithium-ion (Li-ion) battery supplies – the important thing to the vitality transition.
“Li-ion batteries supply efficiency, vitality density, price, and cycle life advantages. Nonetheless, electrification efforts are difficult by a wide range of intersecting elements, together with variations in markets , operations, and insurance policies,” NREL mentioned. “Moreover, Li-ion batteries could include essential supplies which can be briefly provide, equivalent to cobalt, which is a scarce pure useful resource. can be utilized internally.”
LIBRA makes use of system dynamics modeling to investigate the availability chain and consider the financial viability of Li-ion battery manufacturing, reuse and recycling. The device considers adjustments in prices, battery adoption situations and worldwide actions, and the way these elements affect long-term developments within the battery provide chain.

“Though LIBRA can not predict the longer term, this mannequin permits researchers to ask and reply ‘what-if’ questions to realize insights into a fancy and quickly evolving trade,” mentioned NREL. “LIBRA presents an in depth and constant strategy to information analysis and funding to safe the Li-ion provide chain, optimize recycling processes, and guarantee stability and sustainability for nationwide grid and automotive electrification.”
LIBRA’s system dynamics evaluation tracks the availability and circulation of supplies and prices over time for manufacturing and recycling. It consists of superior suggestions loops that sign adjustments in chain levels. Consequently, LIBRA can present insights into materials availability and demand for lithium.
“For instance, if we prolong the lifetime of EV batteries to cut back the general environmental influence of Li-ion batteries, how can we decrease the supply of recycled supplies? There are lots of elements at play ,” mentioned Dustin Weigl, a mobility analysis analyst at NREL.
The device tracks the motion of lithium, cobalt, nickel and different parts via the availability chain. The mannequin repeatedly sheds gentle on the financial viability of recycling these supplies. This highlights the chance for regional recycling potential to offset mineral imports.
Amongst different insights, LIBRA presents helpful information and evaluation for:
- Investments and analysis improvement are wanted to develop the LIB recycling trade
- The significance of battery chemistry and recycling provide chain administration
- Particular regional recycling potential to offset mineral imports
- Financial and employment advantages from battery manufacturing and recycling
“We’re always updating LIBRA’s mannequin construction and information based mostly on the most recent developments inside the transportation and recycling industries,” Weigl mentioned. “Expertise advances transfer rapidly, however LIBRA is designed to adapt to next-generation cell chemistries, battery designs, and storage techniques.”
