Worldwide capacity of lithium-ion batteries for electric vehicles will multiply more than 10-fold by 2020

Improvements in lithium ion (Li-ion) battery technology are helping to accelerate the worldwide market for electric vehicles (EVs).

In the last few years, automakers have shifted from nickel-metal hydride (NiMH) batteries to Li-ion batteries. This shift represents a major endorsement of Li-ion chemistry and its ability to perform consistently in an automotive environment. According to a new report from Navigant Research, total worldwide capacity of Li-ion batteries for transportation applications will increase more than ten-fold, from 4,400 megawatt-hours (MWh) in 2013 to nearly 49,000 MWh by 2020.

"Li-ion technology continues to improve, as increased energy densities translate into smaller and lighter battery packs with more power," says David Alexander, senior research analyst with Navigant Research. "At the same time, leading battery cell manufacturers have built new factories utilising the latest production techniques, including greater automation and faster throughput. This will lead to a reduction in the cost per kilowatt-hour (kWh) over the next few years, provided that volumes continue to increase."

The market for Li-ion batteries will primarily be driven by the growth of battery electric vehicles (BEVs), as they utilise much larger battery packs than plug-in hybrid electric vehicles (PHEVs). Today, most BEVs use battery packs ranging from 16 kWh to 85 kWh, compared to PHEVs that typically use packs ranging from 4 kWh to 16 kWh. Additionally, many recently introduced hybrid vehicles, such as the Honda Civic Hybrid, use Li-ion batteries, and the percentage of hybrids using Li-ion technology is expected to grow steadily as automakers update their models.

The report, "Electric Vehicle Batteries", provides a detailed examination of the growing market for Li-ion batteries, including profiles of all of the leading Li-ion battery manufacturers. Forecasts for revenues from Li-ion batteries, segmented by vehicle type, are included, along with vehicle roadmaps for hybrid, PHEV, and BEV sales by region. The report also includes a review of competing energy storage technologies, including ultracapacitors and nickel-metal hydride batteries. An Executive Summary of the report is available for free download on the Navigant Research website.
