CATL developing new battery materials to improve energy density
CATL, whose clients include Tesla, VW, BMW and Ford, is the world's biggest battery maker accounting for more than a third of the sales of batteries for electric vehicles worldwide.

The new material technology known as M3P can enable an electric vehicle to run 700 km (430 miles) per charge combined with CATL's next generation of battery pack technology, Zeng Yuqun said at the World New Energy Vehicle Congress in Beijing on Saturday.
The new materials will also lower the costs compared to nickel and cobalt-based batteries, he added."
They didn't say when production will start, but I think that it's safe to assume that early Oceans won't have this battery.
