BYD (1211.HK) vs CATL (300750.SZ) comparison. EV manufacturer vs battery supplier — which Chinese EV stock wins in the lithium cycle?
BYD makes both the EVs and the batteries — giving it a cost advantage when lithium is high and a double benefit when lithium falls. World's largest EV seller by volume with brand strength in China and growing globally.
CATL has 35% global battery market share and supplies Tesla, BMW, Volkswagen and most major OEMs. Its margins are most directly tied to lithium prices — falling lithium is a massive margin tailwind for CATL.

Lithium carbonate is currently at $17000/t — down 80% from the 2022 peak of $80,000/t. This is a massive input cost improvement for both companies. CATL benefits more directly (battery materials = ~60% of CATL costs) while BYD benefits across its whole vehicle cost structure.
