Could a Tesla Model S with such batteries theoretically go 500 miles on a charge?
Amprius, a California start-up that’s developing lithium-ion batteries with silicon anodes, announced it raised $30 million to accelerate commercialization of high energy batteries.
“Amprius will use the funds to commercialize its high energy and high capacity batteries and further develop the next generations of its advanced batteries.”
“SAIF Partners, a leading Asian private equity firm, led the financing, in which all of Amprius’ previous investors participated. Amprius’ Series A and B investors include Trident Capital, VantagePoint Capital Partners, IPV Capital, Kleiner Perkins Caufield & Byers, Chinergy Capital, Google Chairman Eric Schmidt, and Stanford University.”
We still don’t know what “high energy batteries” really means in terms Wh/kg, but it should at least double current lithium-ions because silicon anodes have great potential (and lots of problems too).
$30 million in Series C funding comes after Amprius started production cells on a pilot production line for advanced battery development in Nanjing, China for demonstration purposes.
The cells have a volumetric energy density of 580-600 Wh/L depending on size. None of these cells are currently appropriate for EVs, but if the company raised $30M, there must be some potential to introduce it on the market.
Andrew Yan, Founding Managing Partner of SAIF Partners stated:
“Amprius’ advanced technologies address consumer demand for high energy, long life batteries. 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.”
Dr. Kang Sun, CEO of Amprius commented:
“Amprius products have received significant attention and enthusiastic responses from customers worldwide. Series C funding will hasten the commercialization of our high energy and high capacity batteries and the on-going development of silicon-based anodes, advanced cathodes, and innovative manufacturing processes.”
