Solar panels and battery storage

We make lithium ion batteries a sustainable solution.

Many electric vehicle (EV) batteries can be reused before recycling. RePurpose Energy is focused on reusing EV batteries to create reliable, low-cost “second-life” energy storage systems. In doing so, we maximize the value of these batteries, strengthen the resilience and sustainability of battery supply chains, and support the global transition to renewable energy.

A circular economy for electric vehicle batteries.
