The electric vehicle (EV) industry is constantly seeking ways to address the challenge of reducing or mitigating the use of lithium in EV batteries. In a groundbreaking development, Microsoft and the U.S. Department of Energy’s Pacific Northwest National Laboratory may have found a solution that could potentially decrease lithium usage by up to 70%.
Researchers utilized artificial intelligence (AI) tools to narrow down 32 million potential inorganic materials to 18 promising candidates, as reported by the BBC. Among these, they successfully created a battery prototype that incorporates a new substance known as N2116, a solid-state electrolyte. In a significant test, the researchers powered a lightbulb using this innovative battery design.
Although electric vehicles are much more environmentally friendly than their gas-powered counterparts, the extraction of lithium for their batteries poses significant environmental concerns. The lithium mining process is water-intensive and leads to land degradation, as well as contamination of nearby water sources. Moreover, lithium is a non-renewable resource, and if its usage continues at the current pace, accessible reserves may eventually be depleted.
While solid-state batteries have long been considered the “holy grail of batteries” due to their potential for longer ranges, faster charging times, and reduced combustion risk, scientists worldwide have been striving to develop a viable option for EVs. This recent breakthrough by Microsoft and the Department of Energy, augmented by AI technology, offers promising prospects for sustainable energy storage solutions.
In addition to solid-state batteries, various other alternatives that eliminate the need for lithium are being explored. Sodium-ion batteries, currently manufactured in sizable quantities in China, show potential in this regard. Additionally, a battery composed of aluminum, salt, nickel, and ceramic materials is under development.
The discovery of this new material by Microsoft and the Department of Energy marks a crucial step in the pursuit of more sustainable and efficient EV batteries. It holds great promise for the future of electric vehicles, offering the potential for reduced reliance on lithium and addressing some of the environmental challenges associated with its mining.

Definitions:
1. Electric Vehicle (EV): A vehicle that uses one or more electric motors or traction motors for propulsion. EVs are powered by rechargeable batteries, which can be charged by plugging into an electric power source.
2. Lithium: A chemical element that is commonly used in the manufacture of batteries, including those used in electric vehicles. It is known for its high energy density and is currently the most widely used material in EV batteries.
3. Solid-State Battery: A type of battery that uses solid electrolytes instead of liquid or gel electrolytes found in traditional lithium-ion batteries. Solid-state batteries are considered to have higher energy densities, better safety, and potentially faster charging times.
4. Sodium-ion Battery: An alternative battery technology that uses sodium ions instead of lithium ions to store and release energy. Sodium-ion batteries are being explored as a potential alternative to lithium-ion batteries due to the abundance of sodium and its potentially lower environmental impact.
