Belgium-based chemicals and materials manufacturer Syensqo has reported growing commercial adoption of its Energain SA076 material in lithium-ion batteries for premium smartphones, as device makers push towards higher voltage operation and energy density.
The company said its Energain SA076 solution is being used in lithium cobalt oxide (LCO) battery systems paired with silicon–carbon (Si-C) anodes operating above 4.53V. These higher-voltage configurations are increasingly seen as a route to boosting performance in next-generation mobile devices, while maintaining safety margins.
According to Syensqo, the material has reached industrial maturity, with multiple validated use cases across leading smartphone manufacturers, particularly in Asia. It is already deployed in flagship devices and is expected to see wider uptake in 4.55V platforms scheduled for large-scale commercialisation in 2026.
The company said Energain SA076 addresses key technical barriers associated with silicon-anode systems, including electrode swelling, while supporting stable performance under demanding operating conditions. The material can be used at loadings ranging from 5% to 40%, depending on cell design and customer requirements.
“Syensqo’s ability to understand the needs of the battery market”
Dr Ludovic Odoni, head of technology, battery and green hydrogen materials platform at Syensqo, said: “Energain SA076 reflects Syensqo’s ability to understand the fundamental needs of the battery market and translate them into tangible performance gains for next-generation electronics, leveraging our deep expertise in materials science.
“As smartphone manufacturers push toward higher energy densities and voltages, our innovative solution enables safer and more reliable battery systems, meeting the most demanding performance requirements. Its rapid adoption in advanced mobile platforms demonstrates strong collaboration between Syensqo, battery manufacturers, and leading OEMs, especially across Asian markets. We are proud to contribute to the evolution of battery technologies powering the most sophisticated consumer devices.”
Syensqo said it is continuing to expand its Energain portfolio to support higher-voltage chemistries in both consumer electronics and electric vehicles, as battery developers seek improvements in safety, cycle life and energy density.
