I was reading a Chinese EV review comparing BYD's Han to Tesla M3. https://tieba.baidu.com/p/7138577846 https://tieba.baidu.com/p/7138577846 The Han uses iron cathode whereas the Chinese-made M3 uses the nickel cathode. The Han is ~6000 USD cheaper, but gets slightly higher range than the M3 (Han has longer city driving range, but worse at high way). This is especially impressive when the Han is ~400KG heavier than the M3. Both cars have comparable charging speed (31%-100% for 1hr 15min). The reviewer concluded that the Han is a worthy competitor, but Tesla still has an edge at tuning and design. With Tesla switching to iron cathode, I think Tesla can eek out comparable battery performance while maintaining their edge in other areas.
