Jälle Technologies is an Estonian deeptech company focused on sustainable lithium-ion battery recycling. The company utilizes a proprietary process to recover critical raw materials like lithium, nickel, cobalt, and manganese. A key differentiator is its ability to upcycle typically discarded graphite waste into high-value, graphene-like carbon materials for advanced industrial applications. Jälle Technologies secured a €2 million combined pre-seed equity and grant funding round in July 2025. The company's technology addresses a critical bottleneck in the battery recycling chain by repurposing up to a quarter of dead battery mass that is otherwise wasted.
