560Wh/kg lithium-metal cell developed in Germany using nickel-rich cathode

Mon, 09/06/2021 - 15:28 -- paul Crompton

Researchers in Germany have developed a lithium-ion metal cell that reaches 560Wh/kg. 

The energy density— based on the total weight of the active materials— comes from a nickel-rich cathode that enables storage of high energy per mass.

The scientists are from Helmholtz Institute Ulm (HIU) of Karlsruhe Institute of Technology (KIT) in Germany reports the cell has shown the battery’s capacity remains 88% after 1,000 cycles due to its ionic liquid electrolyte.

Researchers first used a cobalt-poor, nickel-rich layered cathode (NCM88) with the commonly used, commercially available organic electrolyte (LP30), but the cell’s storage capacity decreased as the number of cycles increased with this  combination.

By using a dual-anion ionic liquid electrolyte (ILE) the NCM88 cathode reached 560Wh/kg.

The combination of cathode and electrolyte was reported in the journal Joule.

Its initial storage capacity is 214mAh g-1 of the cathode material. The average Coulombic efficiency, i.e., the ratio between discharge and charge capacity, is 99.94%. 

Professor Stefano Passerini, director of HIU and head of the electrochemistry for Batteries Group, said: “In the electrolyte LP30, particles crack on the cathode. Inside these cracks, the electrolyte reacts and damages the structure.

“In addition, a thick mossy lithium-containing layer forms on the anode.” 

For this reason, the scientists used a non-volatile, poorly-flammable, dual-anion ionic liquid electrolyte (ILE) instead to reduce structural modifications on the nickel-rich cathode

Energy Assurance extends lithium-ion battery testing capabilities with new laboratory

Wed, 09/01/2021 - 15:37 -- paul Crompton

Start-up Energy Assurance has expanded its battery analysis capabilities to include large-format cell testing for the electric/hybrid automotive and energy storage systems with the purchase of a laboratory.

The 20,000-square-foot laboratory will enable the firm to expand beyond small-to medium-format battery testing to deliver a third-party resource for battery testing.

The company has begun operating out of the building in Massachusetts, US.

The acquisition extends Energy Assurance's capacity to around 3,000 cell and battery test channels with the ability to test lithium-ion and other chemistry cells and batteries up to 150V and 1,350A.

The centre is in addition to it’s testing laboratory in Atlanta, US. 

The new laboratory uses all MACCOR channels, and was previously owned by an unnamed “leading battery cell manufacturer” for automotive use.

Cindy Millsaps, CEO of Energy Assurance, said: "As the market for larger and more energy-dense batteries grows exponentially, so does the demand for testing to support the growth, making the timing right for this acquisition.

"The acquisition dramatically increases our high-current cycling capacity, and we can now test the full gamut of lithium-ion cells for high-performance products—from small to large and from low to high current—within our facilities." 

Energy Assurance was founded by Millsaps and John Copeland, both former Motorola test laboratory engineers, in 2018.

JV sets goal of establishing commercial lithium-ion battery recycling in Europe

Fri, 11/20/2020 - 09:45 -- paul Crompton

Battery recycling firm Primobius, the German company owned by Neometals and SMS group, has signed a non-binding memorandum of understanding (MoU) with Slovakian lithium-ion cell maker InoBat. 

The MoU provides an evaluation framework for a Primobius-InoBat commercial lithium-ion battery recycling facility in Central/Eastern Europe.

Europe to grasp quarter of lithium-ion production market as global capacity quadruples to 1.3 TWh

Wed, 08/12/2020 - 15:18 -- paul Crompton

Global lithium-ion cell manufacturing capacity could rise fourfold compared to last year's figures to reach 1.3TWh in 2030 thanks in part to the rise of gigafactories being built in Europe, according to industry analysts Wood Mackenzie.

The company’s report shows that 119 battery manufacturing facilities that are operational, under construction or announced by more than 50 vendors will increase global battery making capacity. 

Asia will continue to dominate the industry, with the area’s manufacturers— CATL, LG Chem, BYD, and SK Innovation— leading in the capacity arms race. 

Wood Mackenzie senior analyst Mitalee Gupta said: “Manufacturing capacity in Asia Pacific accounts for 80% of global capacity pipeline. The region will remain the leader of lithium-ion battery production for the next decade.  

“Within Asia Pacific, China dominates the pipeline capacity and is expected to double its capacity from 345GWh this year to more than 800GWh by 2030. 

“In addition to local vendors’ rapid expansion in China, foreign manufacturers such as LG Chem, Samsung SDI and SK Innovation have also been adding new lines after they became eligible for subsidies from the Chinese government in 2019.” 

However, emerging European vendors such as Northvolt in Norway, ACC— the joint venture between Saft and PSA Group (8GWh production plant rising to 24GWh) and Britishvolt could push Europe’s market share from 7% of global capacity, to around a quarter in 2030 amid growing demand for batteries for electric vehicles and energy storage. 

Growth will also be driven by Asian manufacturers investing heavily in new plants in Europe, including: CATL’s Erfurt Plant (Germany), LG Chem’s Wroclaw Plant (Poland), and Samsung SDI’s Goed Plant (Hungary). 

The Americas will maintain its share for the next decade, suggest WoodMac, with pipeline capacity concentrated in the US, and led by Tesla’s Gigafactory in Nevada. 

In terms of battery chemistry, NMC is the mainstream chemistry in operating facilities, followed by LFP. However, announced capacity is often unspecified due to constantly advancing battery technologies and changing market preference.

Skoltech scientists use bespoke lithium-ion cell to view SEI formation

Fri, 06/12/2020 - 10:36 -- paul Crompton

Researchers from Russia’s Skoltech Center for Energy Science and Technology (CEST) have used a bespoke lithium-ion cell to visualise solid electrolyte interphrase (SEI) formation on battery-grade materials.

The specially designed cell allowed the measurements necessary for this direct observation of SEI formation on battery-grade carbonaceous electrode materials using in situ atomic force microscopy (AFM).

Amte Power and Britishvolt sign MoU for UK’s landmark battery gigafactories

Thu, 05/21/2020 - 13:31 -- paul Crompton

UK battery maker Amte Power and Britishvolt announce plans on 20 May to build the UK’s first lithium-ion battery cell gigafactories servicing the automotive and energy storage markets.

The British start-ups have signed a memorandum of understanding (MoU) focussed on enabling the scalable production of lithium-ion batteries to support the UK’s Road to Zero (at least half 50% of new car sales to be ultra low emission by 2030) targets and transition to electrification. 

Britishvolt aims to add to Amte’s 1GWh manufacturing plant plants with a 30GWh factory.
