🔋 Tesla rumored to be behind the $4.3 billion deal with LG Energy Solution.

LG is to provide Tesla with LFP batteries manufactured at its Michigan plant from 2027 to 2030.

In parallel, Tesla is in setting up its own LFP production facility.

China launches world’s first grid-forming sodium-ion battery storage plant The Baochi Storage Station in Yunnan integrates lithium and sodium-ion technologies at scale, a global first, aiming to stabilize renewable energy and cut costs as China accelerates its energy transit...

Sodium-iron batteries at grid scale: 200MW/400MWh, enough to "regulate up to 580 GWh annually."

"The facility supports more than 30 local wind and solar power stations, alleviating the impact of intermittent supply and facilitating the integration of high shares of renewables into the grid."

For many working in battery R&D, this development isn’t surprising—but it does highlight a growing divide in innovation and deployment between the U.S. and other global players.

Good news for batteries...but potentially bad news for domestic manufacturing of batteries.

They also announced the launch of a new sodium-ion battery brand—an interesting move at a time when recent U.S. developments suggest sodium may struggle to be competitive in the current market landscape.

🔋 Big Battery News today! 🔋

CATL just announced a major breakthrough that brings battery performance on par with internal combustion engines. Notably, they’ve developed an auxiliary battery that eliminates the use of graphite—

The University President Willing to Fight Trump Christopher L. Eisgruber of Princeton University talks about the administration’s move to freeze billions of dollars in funding to higher education institutions.

President Trump has frozen billions of dollars in federal funds in an attempt to rid higher education of what he calls its woke ideology. Our reporter spoke to the president of Princeton University, Christopher L. Eisgruber, who has vowed to fight.

Listen to "The Daily."
