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 AND SYSTEMS
LiNa’s energy storage systems take a radical approach to thermal management, providing customers with low-cost and high performance energy storage even in high ambient temperatures.
Our cell design integrates the battery terminals directly into the cell casing, enabling stacking of cells into modules without the need for busbars and with minimal voidage.
LiNa systems run at an internal temperature of 250°C and for good reason. Our systems replace conventional liquid cooling and refrigeration with passive vacuum insulation and we’ve proven that when you remove the need to keep cells cool, your costs are lower and performance actually improves: we’re proud to deliver system round-trip efficiency at 92% and above.
Applications
Our low-cost solid state sodium batteries have been developed specifically to serve the renewable energy storage market.
