The Wall Street Journal (WSJ) reported on the 14th (local time) that Microsoft is investing in battery startups.

Microsoft’s $1 billion Climate Innovation Fund is investing in Silicon Battery Startup Group 14 Technologies in the United States.

However, the specific size of the investment is not known.

Group 14 currently has an enterprise value of just over $3 billion.

It is a company that develops silicon anode materials for batteries that can rapidly expand electric vehicle power supply and dramatically reduce charging time.

Not only Microsoft, but also Oman’s sovereign wealth fund and private equity fund Lightrock’s climate fund are investing in Group 14. Group 14 attracted $210 million from them.

Group 14 was recently supported by the U.S. Department of Energy. Last year, $100 million was provided to Group 14 under the Infrastructure Act.

In addition to Group 14, money continues to roll in.

Earlier this year, it received $400 million from German sports car brand Porsche, Reverse Phone Holdings, and a joint venture between BlackRock and Singapore’s sovereign wealth fund Temasek.

With the investment of Microsoft, Group 14’s corporate value has exceeded $3 billion.

Group 14 in Woodinville, Washington, is confident that its silicon anode material is more efficient than conventional graphite anode materials and will enable stronger battery development.
