Talga Group Limited (ASX: TLG) announced on 12 November 2026 that its Talnode C natural graphite anode had achieved impressive results in an ultra long life lithium ion battery developed by KRI. KRI is a wholly owned subsidiary of Japanese energy group Osaka Gas.

The battery has completed more than 8,000 charge cycles and retained 75% of its original capacity. It is approximately five times the lifespan of conventional lithium ion cells, which typically achieve around 1,600 cycles.

The technology has the potential to provide electric vehicles with a cumulative driving range of approximately 1 million kilometres. It could also significantly extend the operating life of battery energy storage systems.

Talnode-C is a coated spherical purified natural graphite anode which Talga manufactures from its Swedish graphite resources. The production process uses renewable energy; proprietary technology which results in a low emissions product with a traceable supply chain.

KRI's advanced cell design has an aim to make electrode reactions more uniform. Such an approach will reduce non uniform reactions by approximately 50% compared with conventional cells and will limit battery degradation caused by lithium plating and gas generation. Its technology will support both fast charging and low temperature charging.

The news is an important third party validation for Talga because KRI independently assesses battery materials from multiple suppliers. The company has identified low resistance and high crystallinity as well as its homogeneous graphite structure as suitable for its demanding cell design.

The technology could open up significant opportunities in applications that require frequent battery use such as electric vehicle fleets and robotaxis. Battery energy storage systems could also benefit because longer battery life can reduce replacement needs and lower the overall cost per kilometre driven or kilowatt hour delivered.

Longer life batteries could also reduce lifecycle emissions because fewer replacements would be required. That would complement Talga's renewable energy driven manufacturing process and its Swedish supply chain.

KRI has now advanced its customer evaluation programme towards commercialisation. Talga is supporting the sample and pilot phases as both companies target a scale up to mass production in 2030.
