China's output of storage batteries to power new energy vehicles (NEVs) leaped 163.4 percent year on year to reach 219.7 gigawatt-hours (GWh) in 2021 as the NEV industry continued to boom, industrial data showed.

The output of lithium iron phosphate batteries stood at 125.4 GWh last year, skyrocketing 262.9 percent from a year ago, data from the China Automotive Battery Innovation Alliance showed.

China also produced 93.9 GWh of ternary lithium batteries during the period, up 93.6 percent year on year, the data showed.

Sales of new energy vehicles (NEVs) were exceptional last year, surging approximately 160 percent to 3.52 million units, according to the China Association of Automobile Manufacturers (CAAM).

The booming NEV sales followed the gradual improvement of China's supporting infrastructure. By the end of 2021, China had built 75,000 charging stations, 2.62 million charging piles and 1,298 battery swapping stations.
