Advanced battery anode materials and graphene additives provider Talga Resources announced that its UK subsidiary, Talga Technologies, has gained funding under the UK Government’s ISCF Faraday Battery Challenge initiative to develop Talga’s graphitic anode for solid state batteries.
Faraday represents a £246 million UK Government funding initiative for battery research, development and scale up of facilities to help create a new supply chain for battery production in the UK and income from battery technologies.
Solid-state batteries are an emerging form of rechargeable battery technology with potential to combine high energy and high power with improved safety. They work by using a solid-state electrolyte made of polymer, ceramic or glass material instead of the (more flammable) liquid electrolyte of today’s lithium-ion (“Li-ion”) batteries.
A range of automotive manufacturers including Toyota, Volkswagen, Hyundai and BMW have declared their goal is to incorporate solid-state batteries into their vehicles by 2025. Other companies such as Dyson and Bosch are active in this space through various investments in start-ups.
A report by IDTechEx predicts the solid-state battery market to be worth in excess of US$4bn by 2026.
While solid state batteries are theoretically capable of very high performance, in practice they can suffer a range of technical and commercial issues that have hindered development, particularly for larger scale applications such as electric vehicles (EVs). None of the solid-state batteries reported to date exceed all of the performance and economic requirements of today’s best Li-ion batteries in EVs.
A major bottleneck of solid-state development is the anode, where the use of metallic lithium can cause a range of issues leading to slower charge/discharge characteristics, safety issues both within the battery and in mass production, and higher cost. Talga aims to overcome these issues with a new high capacity graphitic carbon composite anode, Talnode-E, designed to have multiple advantages including faster charge and higher power, easier processability, safer handling, highly scalable industrial manufacturing and lower costs.
Talga Managing Director, Mr Mark Thompson said that securing this grant and partnerships with both commercial and R&D partners is another solid step in Talga’s advancements as a battery material and technology supplier.
“This new anode product, Talnode-E, joins our range of advanced battery materials designed to provide leverage to current and emerging battery technologies, delivering ongoing opportunities for growth,” commented Mr Thompson.
“We are seeing increased customer demand for solid state batteries and have attained non-disclosure agreements with leading electronic and automotive companies looking to test our anodes based on our 100 per cent owned Swedish graphite supply.”
