The oversupply of battery factories being constructed globally is set to exceed the demand for lithium-ion cells in the coming years, according to a report by BloombergNEF. The surge in battery production is driven by the increasing demand for electric vehicles and energy storage solutions. By the end of 2025, the global battery industry is projected to have the capacity to produce over five times the number of cells needed that year, creating a challenging situation for new entrants in the battery market.
