For the record, Tesla’s gigafactory in the US state of Nevada officially began making 2170 lithium-ion battery cells for its Powerwall 2 and Powerpack 2 energy storage systems on January 4, the firm said.
The new cell — with dimensions of 21mm by 70mm, hence 2170 — is thicker and taller than the previous 18650 standard cell format.
Tesla CEO Elon Musk has been boasting about the new cell for months. “It’s the highest energy density cell in the world and also the cheapest,” he said.
“We’ve flipped the switch on cell production at the Gigafactory,” Tesla posted on its Facebook page, alongside a video showing the battery cells, which were jointly designed by Tesla and Panasonic, on the factory production line.
The much-anticipated cell for the Tesla Model 3 car will begin production in the second quarter of 2017, and by 2018 the site should produce 35 GWh/year of lithium cells.
Tesla broke ground for the gigafactory in 2014 and the present 1.9 million square feet area is just a third of the anticipated final size, which will make it the biggest building in the world, Tesla claims.
Australian utility Alinta Energy announced on April 12 it had switched on the country’s biggest industrial application lithium ion battery at its Newman Power Station in the Pilbara region of Western Australia. The 30MW/11.4MWh battery is capable of operating as a stand-alone system or can supply power if one or all of the station’s read more
Wind power company Siemens Gamesa Renewable Energy — created last April from a merger between Gamesa Corporación Tecnológica and Siemens Wind Power — has been commissioned to build a wind farm in Australia incorporating a 20MW/34MWh lithium-ion battery, the company announced on April 10. The company has been awarded an engineering, procurement and construction read more
Kraftwerksbatterie Heilbronn, the joint venture between German firms Bosch and utility EnBw, announced on April 13 it had commissioned a 5MW/5MWh lithium ion energy storage system for primary control reserve at EnBw’s coal-fired power plant in Heilbronn, Germany.
