Core Viewpoint - The article discusses the shift in the electric vehicle (EV) battery market from ternary lithium batteries to lithium iron phosphate (LFP) batteries, highlighting the reasons behind this transition and the implications for the industry [1][10]. Group 1: Market Dynamics - In 2019, ternary lithium batteries held a market share of 65% in new car sales, but by recent years, LFP battery installations have exceeded 80%, pushing ternary lithium's share below 20% [4][5]. - High-end vehicles, previously associated with ternary lithium batteries, are now increasingly adopting LFP batteries, indicating a significant change in consumer perception [6][7]. - The price of vehicles is no longer a barrier for using LFP batteries, as even luxury models are now equipped with them [6][7]. Group 2: Technical Comparison - Ternary lithium batteries are composed of nickel, cobalt, and manganese, which are more expensive and have limited global availability, while LFP batteries are based on more abundant materials [12][16]. - Despite the higher energy density of ternary lithium batteries, LFP batteries have advantages in terms of safety, longevity, and cost-effectiveness, making them more appealing as subsidies for EVs decrease [19][21][35]. - Innovations in LFP technology, such as rapid charging capabilities and improved thermal management, have enhanced their performance, making them competitive with ternary lithium batteries [38][44]. Group 3: Industry Implications - The dominance of LFP batteries in the market is largely attributed to Chinese companies, which control over 95% of the global LFP battery production and have advanced in key technologies [60][61]. - International manufacturers are now investing in LFP battery production, often relying on Chinese technology and materials, indicating a shift in the global supply chain [62][66]. - The article suggests that the future of EV batteries may not solely depend on chemical properties but rather on cost-effectiveness and durability, which LFP batteries provide [72][74].
