Blue Current secures $80M from Amazon to make safer silicon batteries for electric vehicles and energy storage, supporting US manufacturing and clean energy.

Blue Current, a California-based business manufacturing silicon solid-state batteries, has raised $80 million in a Series D funding led by Amazon. Other investors are Koch Disruptive Technologies, Piedmont Capital, Allen & Company, and Rusheen Capital Partners. Blue Current manufactures advanced silicon battery technology and plans to market it. CEO Susan Stone stated that the business's technology can meet the needs of both electric vehicles and stationary energy storage. Stone supported a "de-risked approach" to battery adoption that increases US manufacturing capacity.

Silicon solid-state batteries are considered safer than normal lithium-ion batteries, as they do not catch fire. Kevin Wujcik, co-founder and CTO of Blue Current, stated that the company's design improves the density of energy, battery life, and charging speed. "Safety is always our top priority, which led us to our silicon-based design," Wujcik added. Blue Current, has been focused on marketing its battery technology. Their batteries make use of silicon and elastic polymer anodes from the ground, as well as completely dry electrolytes. The business claims that its batteries can be manufactured with the same technology that produces the normal lithium-ion cells.

After the funding, James Hamilton, the senior vice president of Amazon will join Blue Current's board. Hamilton stated that the company can reduce the cost of solid-state batteries and speed up their adoption for energy storage and electric vehicles equally. With Amazon's support, Blue Current aims to reinvent battery production in the United States. Leading to the development of safer and stronger batteries that quickly charge EVs and also improve renewable energy storage. This also supports speeding up the worldwide shift to clean energy.
