Lithium-sulfur batteries contribute to reducing the carbon footprint of electric vehicles (EVs) in several key ways:
- Lower Material Emissions: Unlike traditional lithium-ion batteries, lithium-sulfur batteries do not use nickel, cobalt, manganese, or graphite. This reduction in the use of these materials lowers the overall carbon footprint of the battery. Lyten estimates a 60% lower carbon footprint compared to the best-in-class lithium-ion batteries.
- Abundant and Local Materials: The raw materials for lithium-sulfur batteries can be sourced and produced locally in regions like North America or Europe. This local sourcing enhances regional supply sovereignty and reduces the environmental impacts associated with long-distance material transport.
- Energy Efficiency and Density: Lithium-sulfur batteries, such as Lyten’s LytCell, offer more than twice the energy density of conventional EV batteries. This higher energy density enables lighter EVs, which can improve overall efficiency and reduce energy consumption over the vehicle’s life cycle.
- Sustainable Manufacturing: Lyten emphasizes the use of renewable power for manufacturing and the potential for production in existing gigafactories. This approach minimizes the need for new infrastructure and promotes sustainable production processes.
- Long-Term Emissions Reduction: By reducing the carbon footprint of both the battery production process and the vehicle’s lifecycle emissions, lithium-sulfur batteries can lower the overall environmental impact of EVs. Lyten notes a reduction of up to 62% in the lifetime emissions of vehicles powered by lithium-sulfur batteries.
Overall, lithium-sulfur batteries offer a promising alternative to traditional lithium-ion batteries, with significant potential for reducing greenhouse gas emissions across the EV supply chain.
