Argonne boosts silicon anode performance in lithium-ion batteries with new electrolyte mixture

Fri, 10/11/2019 - 10:44 -- Paul Crompton

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed an electrolyte mixture and additive they claim boosts the energy density of next generation lithium-ion batteries by up to 50%. 

To develop its electrolyte additive the scientists added small amount of a second salt containing doubly or triply charged metal cations magnesium (Mg2+), calcium (Ca2+), zinc (Zn2+), or aluminium (Al3+). 

Image by Argonne National Laboratory: shows charging results in doubly or triply charged metal cations, such as Mg2+ (orange spheres), along with singly charged lithium ions (green spheres) being co-inserted from the electrolyte into the silicon (blue spheres) anode material. This process stabilises the anode, enabling long term cycling of lithium-ion batteries.

Russia to ignore lithium-ion and lead-acid in growing ESS industry

Fri, 10/04/2019 - 12:28 -- Paul Crompton
Russian Minister of Energy Alexander Novak

Russia’s energy storage system (ESS) market is forecast to reach $3 billion by 2025 as production costs fall during the next five years, predicts the country’s Ministry of Energy.

However, neither lithium-ion nor lead-acid was included in an approved state program that will run until 2025 for the development of ESSs in Russia.

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."
