$11M European project seeks to increase lifetime and energy density of automotive Li-ion batteries; second-life use
A €8.4-million (US$11-million) European research project will seek to increase the lifetime and energy density of large-format automotive Li-ion batteries, with a target of a 4,000-cycle lifetime at 80% DOD (depth of discharge) and an energy density of 250 Wh/kg. The goal is a commercial pre-product by the end of the project in September 2016.
The Batteries2020 project approach is based on three parallel strategies: 1) highly focused materials development; 2) understanding aging and degradation phenomena; and 3) routes to reduce battery cost, including second-life use. The project, led by Basque R&D Center IK4-IKERLAN, is receiving €5.9 million (US$7.8 million) in funding from the EU’s 7th Framework Programme.
The project participants include Centro Ricerche Fiat SCPA; Aalborg Universitet; Vrije Universiteit Brussel; Umicore SA; Leclanche SA; Abengoa Research SL; Rheinisch-Westfaelische Technische Hochschule Aachen; and Kellen Europe S.A.
The team will seek to improve cathode materials based on nickel/manganese/cobalt (NMC) oxides, as such materials have a high chance to be up-scaled and commercialized near-term.
The researchers propose starting with current advanced cells and developing two improved generations of NMC materials and cells towards high performance, high stability and cyclability.
To develop further understanding of aging phenomena and degradation mechanisms, the team is proposing the development of robust testing methodology which will be improved in several steps. Combined accelerated, real tests, real field data, post-mortem, modeling and validation will provide a thorough understanding of aging and degradation processes.
As a pathway to reducing battery costs, the project team will analyze the potential reuse and recycling of batteries for providing economic viable project outputs.
The batteries that will be developed in Batteries2020 project will be used to store energy produced in industrial as well as domestic facilities.
Batteries2020 is part of the EU’s Green Car initiative which is seeking to generate the knowledge needed to improve the performance of electric cars.
