# cylib - Next Generation Battery Recycling

> cylib transforms end-of-life batteries into critical raw materials, strengthening resilient European value chains through sustainable battery recycling technology.

cylib is a German battery recycling company founded in 2022 by Dr. Lilian Schwich, Paul Sabarny, and Dr. Gideon Schwich. Born from cutting-edge research at RWTH Aachen University, cylib develops and operates proprietary technology that recovers all elements within lithium-ion batteries with 90% recycling efficiency.

## What cylib does

cylib operates end-to-end battery recycling facilities that transform waste batteries into high-quality raw materials for new battery production. The company processes three main input streams:

- **End-of-life batteries**: Complete spent batteries from electric vehicles and other applications
- **Production scraps**: Manufacturing waste from battery production facilities  
- **Black mass**: Pre-processed battery material from other recycling operations

## Technology and process

cylib's proprietary recycling technology features:

- **Holistic recovery**: Extracts all critical elements from lithium-ion batteries including lithium, graphite, nickel, cobalt, and manganese
- **Water-based lithium and graphite recovery**: Proprietary process that drastically minimizes chemical use compared to traditional methods
- **90% recycling efficiency**: Industry-leading material recovery rates
- **80% reduced carbon footprint**: Verified by external lifecycle assessment compared to raw material extraction
- **100% renewable electricity**: All production powered by renewable energy sources

## Products

cylib produces five main recycled battery materials:

### cylium® (Lithium)
High-purity lithium carbonate and lithium hydroxide recovered using proprietary water-based technology with minimal environmental impact.

### cygraph® (Graphite)  
High-quality graphite recovered through resource-efficient processes, available in various grades for battery and materials manufacturers.

### Nickel compounds
Customized nickel products meeting partner specifications for chemical form and purity, enabling reuse in battery manufacturing.

### Cobalt compounds
