In a groundbreaking shift, SNE Research forecasts China's sodium-ion batteries to enter mass production by 2025, targeting two-wheelers, small EVs, and energy storage. By 2035, their cost is expected to undercut lithium iron phosphate batteries by 11% to 24%, creating a colossal $14 billion annual market. Characterized by lower energy density but higher electrochemical stability and cold resistance, sodium-ion batteries promise a complementary role alongside lithium batteries, fueling the new energy sector's growth. Amidst soaring lithium prices, this resurgence marks a pivotal turn, with China poised to lead the charge in revolutionizing the global energy storage landscape.
