Lithium-ion batteries are the workhorses of the global EV industry, accounting for up to 99% of the batteries installed in EVs as well as hybrids. These batteries currently come in two main configurations, depending on which cathode materials are used: NMC batteries use lithium, manganese, and cobalt oxide, while LFP batteries use lithium, iron, and phosphates. The efficiency of a battery is expressed in energy density and measured in watt-hours per kilogram (Wh/kg); conventional lithium-ion batteries currently have an energy density of under 300 Wh/kg. Yet as of May 2023, the vast majority of the batteries in China — around 75% — have an energy density well below this threshold, less than 160 Wh/kg, as per CAEV data. More powerful batteries whose energy density is above 160 Wh/kg account for only 18.1% of all batteries in China, and this proportion has dropped significantly from 31.6% in May 2022.With the rush to make EV batteries to meet hoped-for EV growth, the quality of China’s battery supply has been diluted.
