The ultra-high compaction NFPP (polyanion) cathode material developed by Puna Energy made its global debut at the 2025 CIBF Shenzhen International Battery Fair. The introduction of this material will rapidly increase the capacity of mainstream 160Ah batteries to 190Ah.
Puna Energy has completed the construction of the world's first fully automated mass production line for sodium-ion battery cathode materials, with an annual capacity exceeding 10,000 mt. Its products have been applied as planned in Shanghai's ESS demonstration projects, including projects by Shenergy Group and Shanghai Airport Group.
