Chinese Lithium-Ion Battery Market to Nearly Double to $9.2 Billion in 2016
The Chinese lithium-ion battery market will nearly double to $9.2 billion in 2016, as volumes grow 129 percent to 44.3 GWh. This impressive growth will occur even though demand for emerging electric vehicles will still trail government’s ambitious projections, Lux Research reports.
The compound annual growth rate (CAGR) for battery volumes will be 18.2 percent while revenues, pegged at $5.0 billion in 2011, grow at a slower rate of 12.8 percent as average selling price dips 20 percent to $207 per kilowatt-hour (kWh) in 2016.
“The consumer electronics market continues to dominate the Li-ion battery market but emerging applications are where the hype is and where policy is being focused,” said Zhuo Zhang, Lux Research Associate and the lead author of the report titled, “Hype vs. Policy: The Chinese Market for Lithium Batteries.”
“The markets for electric bikes and electric vehicles are anticipated to grow fast in a few years but less than 100,000 new-energy vehicles will be sold in 2016, a far cry from the seven-digit target that has battery developers salivating,” Zhuo added.
