SHANGHAI, May 13 (SMM) - The lithium hydroxide market shifted to a supply surplus of 1,492 mt in April. Under the impact of the pandemic, domestic demand was sluggish and exports declined. This, coupled with falling prices of lithium carbonate, sent lithium hydroxide prices lower in late April. Entering May, the overall supply increased slightly, while demand remained stable. However, given the recovery of exports, the market is likely to shift to a tight balance.
