The Galaxy Resources share price continued its incredible run and hit a two and a half year high of $3.19 on Thursday. This means the lithium miner's shares have now rallied 220% over the last six months. Investors have been scrambling to buy Galaxy and other lithium miners due to optimism over demand for the battery making ingredient thanks to the growing adoption of electric vehicles and US President Joe Biden's plan to lead a transition to renewable energy. According to Metal Bulletin, China's domestic battery-grade lithium carbonate prices rose to a 14-month high late last week.
