We have covered the discovery and development of silicon battery anodes for over a decade, but most of our breakthroughs have been at the laboratory level. Over the past few years, the technology has moved toward commercialization, and Silicon Valley battery materials company Sila announced the availability of Titan Silicon anodes this month. The new anode, which will be installed in the upcoming all-electric Mercedes-Benz G-Class, promises a 20% increase in range and the potential to significantly reduce charging times to 10 minutes.
Sila announced the availability of Titan Silicon last week, calling the technology high-performance nanocomposite silicon, designed to replace common graphite anodes on a large scale. We estimate that alternative anode technologies could increase battery capacity enough to improve the range of electric vehicles by up to 20%. ) 2023 Lucid Air Grand Touring. We believe future iterations could double those benefits for him.
Gene Berdichevsky, co-founder and CEO of Sila, said: “Our battery and materials team is constantly iterating and improving our chemistries to provide the best and most cost-effective results possible. We want best-in-class solutions that provide better performance, and our solutions offer longer range and faster charging.”
As far as faster charging goes, Sila puts the 10-80% charge time down at 20 minutes. While it doesn’t sound faster than current-gen batteries, such as his 10-80% time with the Hyundai’s 800 V ultra-quick charge, Sila says that his 20-minute time is the pack’s improvement. said to represent It now takes 60 minutes to charge the same 10-80% gap. In the future, we believe we can cut this in half to 10 minutes.
Sila also points out that Titan Silicon is a market-proven graphite anode replacement material, already used in screenless Whoop 4.0 fitness bands that advertise 4-5 days of battery life. Plans are also underway to bring this technology to the Mercedes-Benz fleet of electric vehicles, starting with the all-electric G-Class Mercedes previewed in 2021.

A few months after unveiling the 2021 Concept EQG and previewing the upcoming battery-powered 4×4, Mercedes announced in May 2022 that the production version would feature Cyra’s anode technology. The German luxury carmaker entered into a strategic partnership with his Sila for the first time in 2019 to improve the energy density of batteries by 20-40% with nanocomposite silicon anodes, up to 800 Wh/l at the cell level. I think we can reach that level. The two companies are targeting the mid-2010 launch of the range-extended EQG with Sila anodes.
Sila’s Titan Silicon availability announcement this month comes after it has reached a scaling milestone at its Moses Lake manufacturing facility in Washington, completing development of a new device. The facility plans to begin mass production in late 2024, producing enough anode material to power one million EVs within five years.
Titan Silicon Anodes are drop-in solutions designed to work with any type of battery cell form (cylindrical, pouch, prismatic) and integrate well into battery manufacturing systems. It is designed to be used as a full or partial replacement for graphite, depending on the cell or vehicle manufacturer’s performance goals and product development timelines.
