OneD Battery Sciences is launching its SINANODE process. According to the company, SINANODE seamlessly integrates into the existing manufacturing process, fusing silicon nanowires to commercial graphite powder, which triples the energy density of the anode while halving the cost per kilowatt hour. Higher energy density increases the battery's cruising range, while nanowires shorten the charging time.

The SINANODE process has nothing to do with which graphite is used and the size of graphite particles. Regardless of the particle size, the SINANODE process has built-in uniform dispersion of silicon.

In this decade, we will witness the largest and fastest transformation in the history of the global industry, and the decisions made today will determine which automakers will stand out from the market that will create more than $6 trillion between 2025 and 2030 .

The demand for electric vehicles will be driven by the range, charging time, and cost, and our SINANODE technology addresses each of these purchasing drivers in an important way. —Vincent Pluvinage, CEO of OneD Battery Sciences

In the past three years, graphite suppliers, battery manufacturers, and electric vehicle manufacturers in the United States, Europe, and Asia have tested SINANODE by applying the technology to commercial electric vehicle-grade graphite used in electric vehicle battery anodes.

The main findings and benefits include:

Increase range and battery life. SINANODE successfully integrated silicon nanowires into commercial graphite powders from multiple suppliers and doubled the specific capacity of the anode (capacity> 1000 mAh/g). The SINANODE anode material can then be mixed with graphite to achieve high initial coulombic efficiency (>92%) and a higher anode specific capacity than any state-of-the-art EV battery in more than 1000 full charge/discharge cycles produced today.

lower the cost. SINANODE was developed using commercial manufacturing CVD equipment provided by multiple suppliers, using only a large amount of silane and nitrogen at an attractive cost. Compared with the most competitive anode cost used in electric vehicle batteries today, this reduces the investment and time required to expand the SINANODE step to the number of electric vehicles, while reducing the cost of electric vehicle anodes (in US dollars per kilowatt hour) ) Reduced by nearly 50%.

Seamless integration to improve performance. SINANODE provides fully differentiated global patented technology that can be deployed with multiple existing suppliers on multiple continents to take advantage of their huge investment and the supply chain strategy of leading players in the fast-growing electric vehicle industry. The addition of SINANODE is not an attempt to replace existing suppliers, but to replace inefficient steps in the current silicon additive processing with scalable technology, thereby improving performance and reducing the cost of materials and batteries used in electric vehicles.

In order to deploy SINANODE today, the company also announced its pilot plan to provide electric vehicle OEMs with its own dedicated factory to deploy the SINANODE step, creating a differentiated nanometer for its vision of high-performance lithium-ion batteries and its ambitions for the electric vehicle production cycle in 2024. Silicon configuration.

Senior energy director Fabrice Hudry has joined OneD Battery Sciences as Chief Commercial Officer, responsible for overseeing the production of SINANODE as the company began to deploy pilot production facilities and partnerships. Hudry joined the company after seven years at Samsung SDI as the vice president of energy solutions. He built the company's energy storage solutions (ESS) from the ground up in the United States.

What silicon nanowires can do for electric vehicle batteries is amazing, and represents the industry's most long-awaited innovation. Joining OneD Battery Sciences as the company to launch its pilot program is an incredible new opportunity at the best time, because I have witnessed the ways that SINANODE can immediately reduce costs and optimize performance. I explored the future of battery technology and believe that SINANODE is the only technology that can pave the way for the transformation of realistic solid electrolyte batteries. —Fabrice Hudry

OneD Battery Sciences, formerly known as OneD Material, operates the SINANODE pilot production program to support the development of advanced electrochemical batteries and the expansion of production scale of its industrial partners. In 2013, OneD Battery Sciences acquired Nanosys' nanowire technology (SINANODE) ​​and its Palo Alto R&D activities. Today, the Palo Alto-based company has more than 200 authorized patents and applications for large-scale anode production and next-generation electric vehicle battery design.
