In the evolving landscape of energy storage technologies, lithium-sulphur batteries emerge as a promising alternative, offering higher energy density and lower environmental impact compared to their lithium-ion counterparts.

However, navigating the market for these innovative batteries can be challenging due to their relatively niche status and ongoing development.

This article provides a detailed overview of where you can purchase lithium-sulphur batteries and what price range to expect.

Where to buy lithium-sulphur (li-s) batteries

1.Specialty electronics suppliers

These suppliers cater to specific needs within the electronics industry, including advanced battery technologies. Companies like RS Group and DigiKey might stock lithium-sulphur batteries for professional and hobbyist applications.

2. Research and development firms

Companies focused on developing Li-S battery technology often offer prototypes or small batches for sale, primarily targeting research institutions and industry innovators. OXIS Energy and Sion Power are examples of firms that have been involved in Li-S battery development.

3. Online marketplaces

E-commerce platforms such as Alibaba and Amazon may list lithium-sulphur batteries, especially from suppliers aiming to reach a global market. Caution and due diligence are advised to ensure product quality and authenticity.

4. Direct from manufacturers

Purchasing directly from manufacturers is a viable option for businesses requiring large quantities of batteries for product development or commercial use. This route often allows for negotiation on price and custom specifications.

Price range

The cost of lithium-sulphur batteries can vary widely based on several factors, including capacity, quantity, and the specific application for which the battery is designed. As of the latest data:

  • Small scale for R&D purposes: prices can range from £100 to £500 per unit, depending on the battery's complexity and intended use. These batteries are typically used in laboratory settings or for small-scale prototypes
  • Commercial scale: for larger orders intended for commercial applications, pricing is often customised and subject to negotiation based on volume, specifications, and contractual agreements. Prices per kilowatt-hour (kWh) can be significantly lower than small-scale purchases, reflecting economies of scale
  • Consumer products: as lithium-sulphur technology is not yet widely available in consumer products, pricing information is scarce and speculative. However, as the technology matures and reaches mass production, costs are expected to decrease, becoming more competitive with lithium-ion batteries


While lithium-sulphur batteries hold great promise for the future of energy storage, their current market presence is limited by developmental challenges and niche applications. Potential buyers, ranging from research institutions to commercial manufacturers, should carefully evaluate suppliers and product specifications. As the technology advances and production scales up, we can anticipate broader availability and more competitive pricing, opening new horizons for energy storage solutions.
