The LiNa Platform

Safe, high-performance, low-cost battery solutions for EVs and scale energy storage. LiNa is commercialising advanced performance, lithium and cobalt-free, solid-state sodium battery technology

INTRODUCTION

LiNa’s proprietary, state-of-the-art, sodium battery platform has operational design performance that greatly exceeds lithium-ion technologies on all KPIs at a vastly reduced cost.

LiNa is on track to deliver a safe, affordable, mass-producible solution to accelerate the two global mega-trends of electrification of transport and decarbonisation of energy.

LiNa is not developing a sodium ion battery based upon incumbent lithium ion technology, where lithium ions are replaced by sodium ions conducting in the liquid state.

LiNa’s technology is a modern, high-tech re-engineering of operationally proven sodium/nickel chemistry, where power is produced by sodium ions conducting across a fast sodium ion conducting ceramic membrane in the solid-state.

APPLICATION

LiNa is commercialising safe, low-cost sodium battery technology designed to deliver increased energy density, increased power density and rapid charge/ discharge capability, ideal for electric vehicle and energy storage markets.

LiNa’s state-of-the-art solid-state sodium battery platform has been designed with an operational and techno-economic performance profile ideally suited for the two global mass markets of electric vehicles and utility-scale stationary energy storage.

The future

Solid-state sodium nickel batteries have fundamental safety and supply-chain advantages over lithium ion battery (LiB) technologies.

Solid-state sodium nickel batteries constitute no flammable organics, no lithium, and critically no cobalt. Sodium-nickel chemistry also permits consistent operational cycling over wider temperature ranges than LiBs at very low degradation rates.

Despite these advantages, the mobile telecoms and automotive industries have selected LiB as their industry standard as the dominant consumer electronic market technology since the early 1990s. This was because available commercial sodium-nickel batteries at the time were bulky, with low energy storage densities and very long start-up times (hours). They also did not lend themselves to efficient, low-cost manufacture. LiBs outstanding problems were judged to be easier overcome.

Today the LiBs that currently dominate both the automotive and energy-storage sectors are suffering from serious unresolved safety, supply-chain, performance and cost issues. Safety problems caused by the inherent instability of the Li-ion battery chemistry are worsening as the market pull for increased energy densities intensifies, driven by range anxiety in EVs and desire for increasing single charge run-time. There are critical supply-chain materials that are scarce and expensive such as lithium itself and particularly cobalt, which also carries significant ethical baggage. LiB performance at acceptable weight and cost remains elusive, and non-degrading rapid-charging remains a barrier for accelerated mass market penetration.

LiNa has applied modern materials engineering and mass manufacturing processes to re-engineer the sodium-nickel battery to overcome the performance and processing limitations of the basic design from the 1980s. The LiNa platform has been designed and is being built to deliver safety, increased energy-density and rapid charge/discharge capability. It is constructed from low-cost, recyclable materials making supply chains intrinsically more secure, which results in significant cost advantages.
