Battery makers say methods, supply chains in flux

The industry is scrambling to make the historic transition from internal combustion vehicles to EVs. John Bozzella, CEO of the Alliance for Automotive Innovation, told the audience that automakers and suppliers are looking to spend $515 billion to prepare for the EV era.

Panasonic, which is the primary battery maker for segment leader Tesla, announced last month that it will spend $4 billion to build its second EV battery plant, in Kansas.

Janet Lin, Panasonic’s vice president of strategy and business development, told the audience that Panasonic was preparing to quadruple its battery capacity and that U.S. production will represent a major part of that.

“Battery innovation is not just in the battery technology and the material itself,” Lin said. “It’s also in the designing and building the factories and the manufacturing lines, and to train and manage the work forces to be able to run these factories.”

She said Panasonic intends to continue to evolve its production processes and equipment to achieve higher line speeds and greater automation.

“And we will continue to work on our multisourcing of raw mass as well as increase our local procurement rate,” she said. “But that alone is not sufficient in order for us to be able to meet the demand that we’re seeing.”

She urged the U.S. government to relax its tariffs on battery materials produced overseas until the U.S. industry can get up to speed.

“We encourage the U.S. to continue to further encourage the development of new sources as well as domestic recycling operations,” she said. “We do need more cost-effective access to key global inputs — so, for example, to reduce or eliminate tariffs on key battery materials that are not yet available or not yet qualified at the levels of scale we need.”

Cobalt sourcing has become a thorny issue in the creation of EVs. The ingredient is crucial to battery production, but much of it comes from overseas mines with poor track records on human rights.

Weinberger said GM’s Ultium batteries use 70 percent less cobalt than the automaker’s previous-generation batteries. And GM will continue to improve the chemical composition to reduce it further over the next few years.
