Does standard energy use vanadium ion batteries?

The company has already completed 10 MWh of projects in its home market and now aims to expand internationally. South Korea-based Standard Energy has developed a battery with just 1% degradation after 20,000 testing cycles. The company uses vanadium-ion batteries (ViB). It showcased the ViB at the recent Smart Energy Week in Tokyo.

Why is vanadium a good battery material?

Vanadium offers unique characteristics as a battery material, as it can shed electrons without shifting from its ionic state, ensuring high cycling stability. South Korea’s Standard Energy has developed a battery with just 1% degradation after 20,000 cycles.

How efficient are vanadium redox flow batteries?

The company's chief project and marketing officer, Gyucheol Lee, said that 10 years ago, the company was developing vanadium-redox flow batteries. However, this type of battery could never get above 80% roundtrip efficiency, as electric pumps were needed to move large amounts of electrolyte from tank to tank.

Can a vanadium battery supply be securing a supply chain?

Vanadium is a common material worldwide, and it’s even found in Korea. So securing a vanadium supply is not that difficult. Demand for lithium-ion batteries is soaring, especially with the strong EV demand, and the preexisting battery technologies inevitably come with supply chain risks since they use rare earth materials.

Could vanadium be a safer battery than lithium?

[PARK SANG-MOON] Vanadium, a hard, silvery metal element, has been on an upward demand curve with its price soaring 84 percent over the past 10 years — lifted partly by its potential as a battery candidate that is safer than lithium. And this is where Standard Energy, a Korean start-up, is betting big.

Does vanadium ion battery dissolve?

With no metal dissolution occurring in vanadium-ion batteries, the company has tested its batteries in its laboratory. Cycling them at a strenuous C-rate of 3, with 100% depth of discharge for 20,000 cycles, the company noted a degradation of just 1%.
