Next-gen battery materials encompass advanced solid-state and sodium-ion chemistries designed to offer higher energy density, faster charging capabilities, and lower production costs compared to current lithium-ion batteries.
Addressing safety concerns related to flammability of liquid electrolytes in lithium-ion batteries, supply chain risks due to the scarcity of critical materials, and the need for increased energy storage capacity and faster charging times in various applications including electric vehicles (EVs), stationary storage systems, and portable electronics.
These new materials replace the liquid electrolytes and metal-based cathodes in traditional lithium-ion batteries with solid electrolytes that are non-flammable and more stable, as well as cathodes made from abundant elements like sodium or manganese, which reduce dependency on rare earth metals such as cobalt and nickel.
The manufacturing process involves synthesizing solid-state electrolytes through techniques like sintering or sol-gel methods, and developing new cathode materials using chemical synthesis processes. These steps require precise control over temperature, pressure, and composition to ensure the stability and performance of the final product.
Solid-state batteries are typically built by layering solid electrolyte layers between two electrodes (cathode and anode), while sodium-ion batteries use a sodium-based cathode and graphite or silicon-based anodes. Both processes involve precise material deposition to maintain electrical conductivity and mechanical integrity.
