Faraday Future has formed a partnership with LG Chem to develop battery technology for its planned electric sports car.

The US electric-vehicle company said LG Chem, one of the world's biggest manufacturers of battery systems, will supply lithium-ion cells for its cars' power units.

The two companies said they want to develop higher-density batteries to be used in electric  vehicles.

“LG Chem worked closely with Faraday Future to develop a tailored cell chemistry to optimize the range and safety of our mass production battery hardware,” Faraday Future vice president Tom Wessner said in a statement.

Batteries continue to be the Achilles heel of the burgeoning electric-vehicle sector. At the Paris auto show, which is taking place this week, carmakers touted a new generation of EVs that, in ideal circumstances, can go for more than 300 km on a single charge.

That's more than double the driving range of the first generation of EVs, but critics say that actual performance will likely be less impressive.

Faraday Future, which unveiled an electric sports car concept - the FFZERO1) at the CES consumer electronics show in Las Vegas in January, is  developing connected EVs that, it says "will advance future mobility solutions for society by consistently challenging the status quo, reinventing our processes, and embracing new technologies."

The company, which has built up a work force of 1,400 so far, plans to launch its first car in 2018.
