Solidion Technology has announced the development of a new high‑capacity, low‑cost anode designed to boost the performance of lithium‑ion batteries used across sectors such as commercial drones.
The company reports that the recently discovered anode is formed from low‑cost silicon particles protected by a flexible rubber layer, a combination intended to significantly extend operational range.
The US‑based battery technology provider says it has created multiple approaches for producing silicon‑rich anode materials containing 45%–95% silicon by weight, with the aim of increasing driving and flying ranges by 20%–45%. The core of this advance lies in the use of an elastic or flexible rubber to encapsulate the silicon particles and shield the full anode electrode.
According to Solidion, the materials can be manufactured through processes that are silane‑free and CVD‑free, while also using metallurgical‑grade or reclaimed silicon as a low‑cost feedstock. The company highlights that its rubber protection technology is supported by more than 40 US patents, alongside a portfolio of international patents, addressing long‑standing technical and economic barriers that have limited wider adoption of silicon‑based high‑energy anodes.
Solidion states that it is prepared to scale up production at its existing facility in Dayton, Ohio, and is exploring opportunities to expand manufacturing capacity in other parts of North America.
