The high cost of batteries poses a major barrier to wider adoption of electric cars. An EU-funded project took several steps to increase lifetime and energy density of lithium-ion batteries, while also enhancing safety, cost and performance.
Electric vehicles play an important role in EU plans to reduce emissions of greenhouse gases and air pollutants from road transport. To become more competitive, manufacturing costs of lithium-ion batteries for electric cars and the cost per kilowatt-hours need to be drastically reduced.
