Welcome to Tech News Briefing.

It's Friday, March 20th.

I'm Katie Dayton for the Wall Street Journal.

Demand for electric vehicles is slowing,

and it's leading some companies in the supply chain to switch up their priorities.

That includes the makers of electric batteries,

which are switching to focus on, yes, you guess correctly, the AI industry. We'll be hearing how they're making it work.

Then, we're taking a look at Apple's approach to AI, which is stood apart from competitors

for its comparatively restrained investment. Siri might not be the best product on the market, but Apple is still raking in more than

a billion dollars in AI revenue.

We'll dive in to how.

But first, the makers of electric vehicle batteries are making a new bet, switching up their facilities to create batteries for energy storage.

They hope the move will help with a growing need for powering data centers and balance a falling demand for EVs.

The journal's Jinji Lee joined my colleague Peter Champelli to explain this shift.

So there's been a renewed interest in creating batteries for storing energy.

Can you explain why there's such an interest now in that type of battery manufacturing?

That's kind of where all the demand is.

There has been a lot of interest in anything that can store electricity because of this AI-fueled

data center boom that's going on around the country. And so companies see energy storage

for grids and data centers as a more promising, growthy market.

So now those manufacturers that were in the EV battery business are pivoting.
