Resource Cycle Solutions

Based on the reuse of used lead-acid batteries and with resource utilization as the main investment direction, Tianneng has built a complete industrial ecology of "Lead+M" integrating the collection, storage, transportation, disposal and resource utilization of hazardous (solid) waste. The first fully automatic alloy vacuum ingot casting production line and new copper remover regeneration refining technology have solved the problem of removing copper, nickel, cadmium and tellurium from regenerated lead refining.

Tianneng gives full play to the advantages of the Ministry of Industry and Information Technology's dual whitelist of used power batteries, vigorously promotes the "3 + 5 + N" urban mine development layout, and builds an ecological closed-loop of "Battery Production → Sales → Recycling → Step-Use → Recycling", which can effectively solve the neck link in the circulation area of decommissioned large power batteries. Utilization → Recycling" ecological closed loop, effectively solve the decommissioning of the large power battery circulation area of the neck link, and breakthroughs in the high-value components of the synergistic leaching, multi-dimensional complex metal directional migration and other key technology processes, can be achieved in the waste lithium batteries in the cobalt recovery rate of ≥ 98.5%, nickel recycling rate of ≥ 98.5%, lithium recycling rate of nearly 90%, in the forefront of the industry.
