Technology
Our sodium-metal-chloride battery is built around proven technology based on 1980s sodium chemistry, with modern materials science and advancements in fuel cell ceramics. As well as improving standards in safety, performance and sustainability, we can commercialise faster by reducing lab development time and lowering the cost of deployment. Materials are abundant and thanks to our patented design, our batteries are ideal for mass manufacture.
CELLS
LiNa’s battery cells are the building block of LiNa Energy’s battery platform. The cells utilise proven Sodium-Metal-Chloride chemistry in a breakthrough planar design made possible by our ultra-thin solid ceramic electrolyte.
The electrolyte is a key component of any battery, providing the medium for ions to transport between the anode and cathode electrodes when charging and discharging. Whilst conventional batteries use a liquid electrolyte, LiNa’s solid state ceramic electrolyte reduces ionic resistance and removes unproductive mass: unlocking a two-fold performance improvement in energy densities versus alternatives. Avoiding the need for conventional flammable liquid electrolytes also means LiNa cells are inherently safe, something we’ve had externally validated.
CHEMISTRY
As the world makes rapid progress towards electrification, industry is increasingly reliant on critical raw materials such as lithium and cobalt. Diversification of battery chemistries is critical for long-term capacity growth.
LiNa batteries are constructed without lithium or cobalt. On charge, sodium ions from the sodium-metal-chloride cathode are reduced to sodium metal and travel through the solid-state ceramic electrolyte to the anode compartment, forming an interconnected backbone conductor. On discharge, the sodium is oxidised back to sodium ions and travels through the conductive backbone, recrystallising in the cathode.
MODULES
LiNa Modules provide customers with low-cost, sustainable, and high performance energy storage. Modularity is core to our design process enabling simple system scaling from kilowatts to megawatts.
Our cell design integrates the battery terminals directly into the cell casing, enabling stacking of cells without the need for busbars and with minimal voidage. When LiNa stacks are combined together into a module, the design closely resembles a heat exchanger to optimise thermal management and eliminate the need for refrigerative and liquid cooling in favour of simple fans even in high ambient temperature conditions.
Applications
Our low-cost solid state sodium batteries have been developed specifically to serve the renewable energy storage market.
