The U.S. government is funding a push to reinvent lithium-ion batteries so they contain little or no cobalt, an increasingly expensive metal found largely in the Democratic Republic of the Congo, where activists say workers often toil in inhumane conditions.

The big picture: Cobalt — contained in virtually every commercial lithium-ion battery on the planet — has unusual energy density and the ability to stabilize volatile electrochemistry. But its price has swung wildly given booming demand for electric cars in China, from Tesla, and elsewhere — in addition to electronic devices like smartphones.

  • By seeking to eliminate or seriously reduce the metal's use in batteries, the Department of Energy, along with several startups, may complicate what has been one of the primary quests of the last decade: to create a safer, cheaper battery that lasts much longer than current technology.
  • In a June speech in Washington, D.C., Peter Faguy, a senior manager in the battery research effort at DOE, used the term "blood cobalt" to describe the metal, suggesting that removing it from lithium-ion batteries is a moral issue.

What's going on: The DOE is funding three-year research efforts at Argonne and Lawrence Berkeley national labs.

  • Jason Croy, who is leading the Argonne effort, said that a leading solution is to swap in nickel. That does well in achieving high energy, but so far hasn't proven stable enough for use in commercial batteries. He said manganese is another potential substitute.
  • At Berkeley, Gerbrand Ceder, the project leader, said he is working on an entirely different material — a battery made with disordered rock salt, which he said does not require cobalt for stability. He said the battery can be charged at a high five volts, a key quality when high energy is sought.

The bottom line: Ceder said cobalt may never be removable from electronic devices because the space for a battery is so small that the metal's density is needed.

Scoop: Gina Haspel threatened to resign over plan to install Kash Patel as CIA deputy

CIA Director Gina Haspel threatened to resign in early December after President Trump cooked up a hasty plan to install loyalist Kash Patel, a former aide to Rep. Devin Nunes (R-Calif.), as her deputy, according to three senior administration officials with direct knowledge of the matter.

Why it matters: The revelation stunned national security officials and almost blew up the leadership of the world's most powerful spy agency. Only a series of coincidences — and last minute interventions from Vice President Mike Pence and White House counsel Pat Cipollone — stopped it.

John Weaver, Lincoln Project co-founder, acknowledges “inappropriate” messages

John Weaver, a veteran Republican operative who co-founded the Lincoln Project, declared in a statement to Axios on Friday that he sent “inappropriate,” sexually charged messages to multiple men.

  • “To the men I made uncomfortable through my messages that I viewed as consensual mutual conversations at the time: I am truly sorry. They were inappropriate and it was because of my failings that this discomfort was brought on you,” Weaver said.
  • “The truth is that I'm gay,” he added. “And that I have a wife and two kids who I love. My inability to reconcile those two truths has led to this agonizing place.”
