NanoMalaysia Berhad (NMB), an agency under Malaysia’s Ministry of Science, Technology and Innovation (MOSTI), has revealed a sodium‑ion battery prototype achieving an energy density exceeding 300 Wh/kg, placing it among the world’s most advanced sodium‑ion systems.
The prototype was developed through the NanoMalaysia Energy Storage Technology Initiative (NESTI) in partnership with International Battery Centre Sdn Bhd. NMB said the achievement marks a crucial step toward further development, scaling, and eventual commercialisation, with industry collaborations key to advancing the technology to higher readiness levels.
“By surpassing 300 Wh/kg at the prototype stage, we demonstrate that sodium‑ion batteries can match lithium‑ion performance while offering advantages in cost, safety, and material sustainability,” said Rezal Khairi Ahmad, CEO of NanoMalaysia Berhad. He added that establishing partnerships with industrial off-takers will be essential to advance the technology and protect the interests of both local and international investors.
The breakthrough highlights Malaysia’s growing focus on energy storage innovation and positions the country as a potential leader in sustainable battery technologies.
