NEO Battery Materials Ltd has announced that its NBMSiDE pouch-type full cells have been manufactured to evaluate product performance, viability, and durability in genuine battery charging conditions.
In addition, the company said the “Kick-Off Meeting” for NBM Silicon Anode Plant project has been convened with the engineering design company to streamline terms and efforts for fast-track construction completion.
NEO Battery Materials said it commissioned a third-party evaluation agency for a product performance and viability assessment of NBMSiDE through manufacturing and cycle-testing 500 milliampere/hour (mAh) pouch-type full cells.
To simulate an authentic battery charging/discharging environment, the pouch full cells utilize NMC cathode materials and a composite mixture anode material with 5% to 10% silicon loading of NBMSiDE and graphite.

Following the third party's charging protocols, the company said the tested cells are subjected to a cycle test using a 1C rate (1-hour) charging protocol with dynamic stress tests (DST) and a 100% depth of discharge (DoD), and pouch full cells characterized as high-rate capable cells will be tested with a variety of ultra-fast charging C-rates such as 3C rate (20 minutes) or 5C rate (12 minutes).
In addition, pouch cell electrochemical characteristic evaluations will be conducted in a variety of environments and conditions to confirm the robustness and durability of NBMSiDE, and the third party will provide frequent feedback on progress results.
Through unbiased testing and assessments, NEO Battery Materials said it is making continuous efforts to ensure objective evaluation and to reserve the functional reliability of NBMSiDE silicon material development.
NEO Battery Materials, through its South Korean subsidiary NBM Korea Ltd., started the NBM Silicon Anode Plant project (NSAP Project) at Oseong International Investment Zone in Pyeongtaek City in March 2022.
The contracted engineering process and design company for the NSAP Project will be employing a team of eight engineers for the basic design stage for the project.
The company said the Kick-Off Meeting, which marks the official collaborative initiation of the NSAP Project, was held at the Korea Press Foundation Center on April 5, 2022, with the engineering design company.
The full-fledged mass-production process design had been in progress since March of 2022, and the Kick-Off Meeting was convened to determine and define the fundamental terms of the project and to discuss detailed terms and processes apart from the basic agreement.
NEO Battery Materials said it will commence construction in June 2022 and will follow stringent timelines and protocols as its aims for completion in June 2023.
