Repurposing retired EV batteries to enable longer and sustainable use of Li-ion batteries
The Problem
Energy storage is growing at a phenomenal pace
729 GWh of energy storage needed globally by 2030*
365 GWh of energy storage in US by 2030*
* WoodMackenzie12 million tons of batteries retiring by 2030
227 GWh per year retiring by 2030 *
Independence from material supply limitations
* McKinseyCountries/cities mandating repurposing and recycling
174B$ from Biden administration for EV energy storage market*
Repurposing/Recycling of batteries is criticallly needed
* ReutersEV Battery Repurposing is Expensive
No fixed platform
OEMs, Chemistry, Physical Footprint, Power/Energy Size, Degradation
Wide distribution
Existing BMS designed for new batteries that have tight distribution and are specific to OEMs
Limited by worst performer
One single bad module/pack limits the performance of full ESS
Stacking is costly
Requires significant capex and labor for harmonization
