As electric vehicles grow ever more firmly established, industry experts remind of the crucial role that battery technology plays in fulfilling the sustainability and economic potential of electric vehicles. While auto manufacturers and regional authorities the world over make decisions which lend weight to the spread of EVs, major automakers such as Volvo are set to make the transition to fully electric production, Tesla making waves with its ambitious production targets, and city government’s setting firm end dates for the use of ICE vehicles in their borders, battery manufacturing remains a less discussed area.

Two factors concerning battery production continue to hinder widespread EV adoption, despite the corporate and public sector push on automobile manufacturing and legislation, namely their price and environmental impact. A Bloomberg New Energy Finance report suggests that the price of EV batteries needs to decline by 50% to reach a feasible level, a point they predict the industry will reach by 2026.

However, the greater challenge remains the high environmental cost of the production of EV batteries, a process which is estimated to account for a majority of the emissions caused during their production and a major culprit in raising the emissions to an average twice that of a fuel-burning automobile. This high cost is coupled with the current energy mix in most developed countries which continue to utilize considerable amount of coal-produced energy. At this rate, a report by the World Economic Forum suggests, EVs take roughly nine years to make up for the emissions accrued during production and the charging of EV batteries with less than entirely clean energy and, thus, become greener than diesel cars.

With automotive industry analyst Patrick Hummel leading a group suggesting that global sales of EVs will reach one sixth of all car sales by 2025, the time for improving battery production processes and efficiency is now.
