OneD Battery Sciences presented its SINANODE process, which is now integrated into existing manufacturing processes to fuse silicon nanowires into commercial graphite powders, tripling the anode’s energy density and halving its cost per kWh, according to the company.
The increase in energy density increases the battery life, while the nanowires shorten the charging time. The SINANODE process is independent as to which graphite is used and the size of the graphite particle.
“During this decade, we will witness the largest and fastest transformation of a global industry that’s ever been seen, and the decisions made today will determine which car makers come out on top of a market poised to bring in over $6 trillion between 2025 and 2030 alone,” Vincent Pluvinage, CEO of OneD Battery Sciences.
Pluvinage explained that demand for electric vehicles will be driven by range, charging time, and that SINANODE technology addresses each of these purchase drivers in significant ways.
For the past three years, graphite suppliers, cell manufacturers, and electric vehicle manufacturers in the United States, Europe, and Asia have tested SINANODE by applying the technology to the commercial EV grade graphite used in the anodes of the batteries of the electric vehicles.

SINANODE successfully fuses silicon nanowires with commercial graphite powders from multiple vendors and tripled the anode specific capacity. The SINANODE anode material can then be mixed with graphite, to achieve high initial coulombic efficiency and higher anode specific capacity for over 1000 full charge / discharge cycles than any next generation EV cell in production today.
It was also developed with commercially manufactured CVD equipment available from multiple vendors, using only nitrogen and silane gases available in very large quantities at attractive costs. This move reduces the investments and time required to scale the SINANODE step to numbers of electric vehicles, while lowering the cost of the anodes.
To implement SINANODE today, the company also announced its pilot programs, providing electric vehicle OEMs with their own dedicated plant to implement the SINANODE step, creating differentiated nanosilicon configurations for their high-performance lithium-ion battery vision and ambitions of electric vehicle production cycle 2024.
OneD Battery Sciences is a company created in 2013 based in California, United States, which is a leader in innovations to add silicon to electric vehicle batteries, with 200 patents granted and proven technology to provide silicon anode materials- scale high volume fabrication graphite.
