NMB Unveils High-Performance 300Wh/kg Sodium-Ion Battery Prototype

KUALA LUMPUR, March 2 (Bernama) -- NanoMalaysia Berhad (NMB) has achieved a major milestone in Malaysia’s energy storage ambitions with the development of a Graphene-Enhanced Sodium-Ion Battery prototype delivering energy density exceeding 300Wh/kg, which is amongst the best in the world.

Developed under the NanoMalaysia Energy Storage Technology Initiative (NESTI), the sodium-ion battery utilises a NASICON-based sodium vanadium phosphate (NVP) cathode integrated with graphene nano-additives to enhance electrochemical performance, energy density, and structural stability for next-generation energy storage. Unlike conventional lithium-ion batteries, sodium-ion technology leverages abundant and cost-efficient raw materials, namely sodium or natrium, reducing dependence on critical minerals such as lithium, nickel and cobalt. It also offers improved safety and thermal stability, key considerations for large-scale energy storage and mobility applications. This is in line with the emerging technological shift and market trend towards sodium-based battery chemistry, as demonstrated by CATL (China), Faradion (UK), Natron Energy (US) and Tiamat (France).
