NEO BATTERY MATERIALS UNVEILS BREAKTHROUGH SILICON BATTERY CAPACITY, EXPANDING TO SPACE INDUSTRY WITH SOLID-STATE BATTERIES

Neo Battery Materials Ltd. has launched an advanced high-performance silicon anode product called NBMSiDE P-300 with breakthrough battery capacity. Alongside its core focus on electric vehicles and electronics, Neo is expanding its strategic downstream focus to the space and eVTOL industries through solid-state batteries.

• New high-performance silicon anode product line: NBMSiDE P-300:
  • Breakthrough 43-per-cent to 130-per-cent improvement in initial battery capacity compared with traditional graphite anodes with less material used;
  • Under optimization for pilot production and implementation in full cells.
• Submitted patent application to protect P-300 manufacturing know-how;
• Expanding downstream focus to space and eVTOL industries through high compatibility with solid-state batteries.

The advent of P-300: moving toward commercialization with graphite anode blends

On Aug. 13, 2024, Neo announced coating technology innovations that improved battery cycling performance and Coulombic efficiency. After passing stringent validation tests and exceeding performance thresholds, Neo Battery is delighted to introduce the most advanced silicon anode product called NBMSiDE P-300.

Using P-300 products, Neo further achieved a technological milestone of manufacturing silicon-graphite composite (mixed) anodes with industry-leading battery capacity results. Initial P-300 silicon-graphite anodes demonstrate a 500 mAh/g (milliampere hours per gram) capacity by adding under 7 per cent of silicon. This represents a 43-per-cent higher initial capacity than traditional graphite anodes, additionally saving 50 per cent of materials compared with competitors' silicon anodes.

Furthermore, P-300 exhibits good compatibility with graphite and an uncomplicated silicon-graphite ratio control. Hence, P-300 silicon-graphite anodes can easily achieve an 800 mAh/g capacity -- a 130-per-cent higher initial capacity than graphite anodes. These results signal that P-300 is a strongly favourable candidate for commercial graphite anodes in large cell formats. NBMSiDE P-300 is now under the optimization process for pilot production and implementation within full cell designs and tests.

To protect the proprietary manufacturing know-how, Neo has submitted the related patent application to the Korean Intellectual Property Office (KIPO). Enhanced concepts for engineering silicon particle size through the utilization of key additives during the milling process comprise the core content of the applied patent.

Expanding focus to solid-state batteries for space and eVTOL industries

Recent advancements in NBMSiDE P-300 reinforce that Neo's products are highly applicable and necessary for solid-state batteries. Solid-state batteries are recognized as the most practical battery systems for the space and electric vertical takeoff and landing (eVTOL) industries due to thermal stability with a wide operating temperature range, non-flammable safety and high-energy density.

Spencer Huh, president and chief executive officer of Neo, commented: "In 2025, Neo Battery Materials is committed to diversifying the applications of our advanced silicon anode technology to capitalize on emerging opportunities in the rapidly growing space and eVTOL industries. These sectors represent significant market potential, driven by increasing demand for lightweight, high-performance and thermally stable energy solutions. By targeting these transformative industries, alongside our existing focus on electric vehicles, Neo aims to position itself at the forefront of innovation, addressing critical challenges and advancing energy storage technology to support the next generation of transportation and aerospace applications."

As Neo's products are based on metallurgical, micron-sized silicon with polymer coatings, reducing silicon particle fracturing and adverse side reactions at the electrolyte-electrode interface is essential to mitigate contact loss during cycling tests in solid-state batteries. P-300's enhanced conductivity and improved lithium-ion diffusion would provide stable performance and high compatibility between pure silicon anodes in solid-state batteries.
