Key Findings

  • 01Accurate State of Health (SOH) estimation is crucial for predicting Remaining Useful Life (RUL) and maximizing economic benefits of SLBs.
  • 02Lack of comprehensive degradation data from both first and second life significantly impacts RUL and SOH prediction accuracy.
  • 03Standardized business models, market trend analysis for energy and battery pricing, and governing policies are urgent research gaps for SLB commercialization.
02

Application

Design takeaway

Integrate second-life considerations into product design and develop robust diagnostic tools for assessing repurposed components.

How to apply

When designing products with finite lifespans, such as batteries, consider how components could be repurposed or reused in a secondary application to extend their value and reduce waste.

Project actions

  • 01When researching product lifecycles, consider the 'end-of-life' phase not as disposal, but as an opportunity for innovation.
  • 02Investigate how material properties change over time and how these changes might affect performance in a secondary application.
