Ground-breaking battery research publishedApril 5, 2012
A new Element Energy-led study of the costs and performance of batteries for electric vehicles was published today. It is widely recognised that electrification of drivetrains will be a key aspect of decarbonising road transport, which in turn is required for the UK to meet its medium and long term GHG emission reduction targets.
Batteries are a key component of electric vehicles (EVs) in terms of both vehicle performance and cost (hence sale price). This research, commissioned by the Committee on Climate Change, reviews the current state of the EV battery market and presents projections of future costs and performance to 2050. The team benefited from the expertise of Europe’s largest independent pack assembler Axeon as well as the input of a recognised world leading expert on lithium electrochemistry: Prof. Peter Bruce from the University of St Andrews.
The findings are based on a new detailed cost model of all components of EV battery packs, built after consultation with the industry (battery manufacturers and electrode material suppliers) and review of existing state of the art battery cost models. The model contains a technology roadmap of future lithium-ion chemistries that allows findings to reflect the current R&D efforts. Cost and performance of post-lithium-ion batteries are projected based on an assessment of lithium-air batteries, the most promising technology in terms of energy density.
This research forms an important aspect of the Committee’s analysis of the relative costs of alternative low carbon vehicles from 2020 to 2050 and is used to support the Committee’s recommendations on the types of vehicle that are most likely to deliver cost-effective emissions reductions in future.
