World’s biggest lithium-ion ESS set to get even bigger as Australia continues to embrace renewables

Wed, 11/20/2019 - 14:55 -- Paul Crompton

Just over two years since Tesla’s CEO Elon Musk announced a ground-breaking energy storage project with the type of Twitter fanfare only he can muster the world’s biggest lithium-ion system is about to get 50% bigger.

The 100MW/129MWh Hornsdale Power Reserve (deployed by Tesla in 100 days) in South Australia is being expanded by a further 50MW/64.5MWh as the state aims to transition to net 100% renewable energy generation in the 2030s.

Tesla patents ‘secret sauce’ additive but will ‘million mile’ lithium-ion cell reach commercialisation?

Thu, 10/03/2019 - 15:01 -- Paul Crompton

US electric vehicle OEM Tesla's latest patent suggests it has solved the failure issues of high operating temperatures and voltages in lithium-ion technology to make a battery that will last a ‘million miles’.

Tesla’s lead battery researcher Jeff Dahn and members of the Department of Physics and Atmospheric Science in Dalhousie University suggest their lithium-ion pouch cells have a 6,000 cycle life, or 20 years in grid energy storage applications. 

Chris Hale, from Upgradetech Engineers, told BEST: “Until I can hold in my hand a commercially produced cell capable of several thousand cycles, I will always remain sceptical."

Musk hits out at Panasonic over Tesla battery supply

Thu, 04/18/2019 - 09:10 -- Hugh Finzel

Tesla CEO Elon Musk has blamed “lower-than-expected” battery manufacture from Panasonic for disrupting production of Tesla’s Model 3 electric vehicles (EVs).

Musk said in a post on Twitter that Panasonic’s battery cell lines at the ‘Gigafactory 1’ facility in Nevada amounted to about 24GWh per year— lower than the expected 35GWh— and had “been a constraint on Model 3 output since July (2018)”.

Musk added “Tesla won’t spend money on more capacity until existing lines get closer to 35GWh theoretical”.
