PolyPlus Battery Company

PolyPlus Battery Company is engaged in developing advanced battery technologies. The company has remained operational without interruption since 1991, originating from the development of a lithium/organosulfur battery at the Lawrence Berkeley National Laboratory. The company has received support from a diverse blend of funding sources, including licensing fees, private investments, contributions from the industry, as well as government contracts secured from both the Department of Energy and the Department of Defense. PolyPlus Battery Company invented and obtained a patent for the protected lithium electrode (PLE), a foundational technology facilitating the incorporation of remarkably lightweight metallic lithium anodes into batteries. PolyPlus is currently in the process of further developing rechargeable lithium-sulfur (Li-S) batteries. The initial phase of commercialization will be strategically directed towards applications that prioritize weight efficiency, yielding high-margin opportunities.

NexTech Batteries Inc.

NexTech Batteries Inc. was formed from the successful acquisition of exclusive license rights and patents for lithium-sulfur battery technology that originated from research conducted at the Lawrence Berkeley National Laboratory. The company’s patented methodologies and environmentally conscious materials have led to the creation of batteries featuring energy densities and overall power capabilities that significantly surpass those of the present-generation lithium-ion batteries. NexTech Batteries Inc. is developing a lithium-sulfur battery which encompasses exceptional safety, superior energy density, cost-effectiveness, ethical supply chain practices, and a commitment to environmental responsibility. The company aims to serve the sectors of vehicle electrification, consumer electronics, renewable energy storage, and a multitude of other domains such as military and aviation.

Lyten, Inc.

Lyten, Inc. was initially founded with a focus on employing semiconductor technology for clean hydrogen energy production. However, their journey led to the discovery of three-dimensional graphene, a groundbreaking material with significant potential for innovation and decarbonization. The company first announced its lithium-sulfur battery in the year 2018. Recently, in June 2023 after receiving funding from Stellantis N.V. (Netherlands) the company started the automated pilot production of their lithium-sulfur batteries in the US. The company aims to commercialize lithium-sulfur batteries by the end of 2023. The company has raised a total of USD 410 million in the past few years. Further, the company is planning to provide battery prototypes to their potential customers which include automotive and aerospace sectors and other sectors such as aviation. Through this, the company is aiming to test their battery and benchmark for further commercial applications.

Li-S Energy Limited

Li-S Energy Limited is a company specializing in cutting-edge energy solutions. The company is focused on advancing battery technology, the company pioneer in the development and application of lithium-sulfur and lithium metal cells. With a keen eye on sustainable aviation propulsion, Li-S Energy is actively engaged in partnerships and collaborations to drive innovation in the electric aviation sector. The company has collaborated closely with Deakin University to commercialize more than a decade's worth of research dedicated to advancing lithium-sulfur (Li-S) batteries. By incorporating boron nitride nanotubes (BNNTs) as nano-insulators, these batteries have witnessed enhanced performance and extended cycle life. The company aims to cater to the sectors of automotive, aerospace and consumer electronics.
