SAIF leads funding round for Amprius

A private equity consortium has invested $30m in the battery manufacturer.

Hong Kong-based SAIF Partners has led a consortium of investors in a $30 million series C funding round by Amprius, which included all of the company’s previous investors, according to a statement from the target company.

Amprius is a high energy and high capacity lithium-ion battery maker, currently planning to develop its next generation of advanced batteries.

The company has its lab and corporate headquarters in Sunnyvale, California, as well as operating a lab and production line for advanced battery development in Nanjing, China.

Its existing shareholders include Trident Capital, VantagePoint Capital Partners, IPV Capital, Kleiner Perkins Caufield & Byers, Chinergy Capital, Google chairman Eric Schmidt, and Stanford University. Amprius’ silicon technology was originally developed at Stanford.

The total amount raised by Amprius from its three funding rounds is at least $55 million, after a $25 million series B fundraise was completed in 2011. The series B funding allowed the firm to develop its first commercial product, validate its manufacturing processes and launch a global presence, an earlier company statement said.

“We are delighted to invest in Amprius and accelerate the company’s international growth. SAIF Partners supports Amprius’ short-term focus on consumer electronics and shares the company’s medium- and long-term interest in electric transportation,” said Andrew Yan, founding managing partner of SAIF Partners.

SAIF typically invests in Asia-based businesses in sectors such as IT and telecommunications, consumer, healthcare and financial services. The firm is based in Hong Kong and has about $3.6 billion in assets under management, according to the statement.
