Expansion plans lead EU Commission to open investigation into Samsung’s Hungary lithium-ion battery plant

Thu, 10/17/2019 - 11:06 -- Paul Crompton

An investigation has been opened into Hungary's €108 million ($120 million) pledge to help fund Samsung SDI’s battery cell production expansion plans in Göd (Hungary), the European Commission announced on 14 October.

The Commission is set to investigate whether the financial support was necessary for Samsung to trigger the expansion plans at its existing plant in Göd, which was completed in 2017.

A lithium-carbon dioxide prototype battery that can match the cycle life of lithium-ion has been made after scientists at a US university developed a method of preventing the traditional failure modes of the technology.

Researchers at the University of Illinois at Chicago (UIC) say their prototype has achieved 500 consecutive charge/recharge cycles.

Their findings were published in the journal Advanced Materials.

India plans to build another lithium-ion battery facility after JV sign pact with Gujarat government

Wed, 10/16/2019 - 14:23 -- Paul Crompton

Plans to build a lithium-ion battery manufacturing plant in India moved forward this week with a memorandum of understanding to invest INR49 billion ($690 million) signed between a Japanese joint venture and the state government of Gujarat.

Automotive Electronics Power Private Ltd. (AEPPL)— jointly owned by Japanese firms Suzuki Motor (50%), Toshiba (40%) and Denso (10%)— plan to build a lithium-ion battery production facility in Hansalpur, in the state’s Ahmedabad district.

APS still months from closing investigation into US lithium-ion ESS explosion

Wed, 10/16/2019 - 14:18 -- Paul Crompton

An investigation into the fire at a 2MW/2MWh lithium-ion energy storage system in Arizona, US, is expected to close by the end of the year— eight months after the incident at the Arizona Public Service (APS) owned facility.

The final battery rack from APS’s McMicken site in Surprise is at a forensics laboratory in Michigan for analysis, after a specialty laboratory in Scottsdale removed it last month.

Talga and Leclanché sign MoU to trial graphene silicon lithium-ion battery anodes

Tue, 10/15/2019 - 14:06 -- Paul Crompton

Switzerland energy storage firm Leclanché will evaluate Australian firm Talga Resources’ range of graphene silicon anode products with the intention of developing commercial products for the lithium-ion battery industry. 

The move follows the signing a memorandum of understanding that includes trials to run over a 2-6 month period, and indicative pricing for various volumes of Talnode supply, during the trials and over a three year period.

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."
