China is leading the way on 5G sales, which have slowed in recent months, but are expected to increase as growth recovers in the aftermath of the COVID-19 crisis."5G will be a major source of cobalt demand in the years ahead," said George Heppel, analyst CRU, which expects cobalt demand for portable devices to rise to 73,000 tonnes by 2025 from 45,000 tonnes this year."Down the road we are likely to see some aggressive bidding for cobalt from electric vehicles and mobile phones, where there isn't really a chemistry that can compete with LCO."Electric vehicles typically use cathodes made from nickel, cobalt and manganese, but there are alternatives such as lithium iron phosphate that do not need cobalt.Cobalt demand estimates mostly vary between 100,000 and 130,000 tonnes for this year, doubling to between 200,000 and 260,000 tonnes in 2025.Analysts expect a balanced cobalt market this year and deficits from 2022 as sales of electric vehicles and 5G phones accelerate.

5G demand for cobalt will mean increased supply will be needed apart from EV requirements IMO
