hofer powertrain has introduced a new battery module based on advanced lithium sulfur cell technology, developed in partnership with US cell manufacturer Lyten. The collaboration aims to set new standards for energy storage across mobility, motorsport, marine, aerospace and stationary applications by combining hofer powertrain’s expertise in system integration with Lyten’s next generation cell chemistry.

Lithium sulfur batteries offer a compelling alternative to conventional lithium-ion solutions. By removing nickel, cobalt, manganese and graphite from the bill of materials, the technology achieves a lighter module with higher energy density and improved sustainability. Sulfur’s abundance and low cost further strengthen the supply chain, while the simplified cell architecture supports local sourcing in the US and EU. Projections indicate that Lyten’s cells could deliver up to twice the energy density of current lithium-ion cells, with robust performance across a wide temperature range.

hofer powertrain’s engineering team has tailored the module architecture specifically for pouch cell formats, focusing on electrical load capacity and cycling stability at the system level. The design features a modular approach that supports voltages up to and beyond 800 volts and incorporates a dedicated Cell Monitoring Unit for precise module-level diagnostics. This streamlined structure enables straightforward cell replacement and addresses mechanical, thermal and electrical requirements.

The joint project leverages hofer powertrain’s established validation and testing infrastructure, ensuring that new cell chemistries can be rapidly assessed and industrialized for demanding applications. By integrating lithium sulfur cells into modular battery packs, the partners are targeting CO₂ savings of over sixty percent at scale, while maintaining the high performance and safety standards required by OEMs and Tier 1 suppliers.

Johann Paul Hofer, CEO of hofer powertrain, notes that the company’s longstanding experience in battery development and system integration provides the foundation for bringing innovations like lithium sulfur to market readiness. Dan Cook, CEO and co-founder of Lyten, highlights the growing demand for lightweight, cost-effective batteries using locally sourced materials and sees the partnership as a catalyst for accelerating adoption across electric vehicles, micromobility, drones, satellites and energy storage systems.
