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.

Facebook bans Myanmar military

Facebook said on Wednesday it would ban the rest of the Myanmar military from its platform.

The big picture: It comes some three weeks after the military overthrew the civilian government in a coup and detained leader Aung San Suu Kyi, causing massive protests to erupt throughout the country. Military leaders have been using internet blackouts to try to maintain power in light of the coup.

It's harder to fill the Cabinet

Data: Chamberlain, 2020, "United States of America Cabinet Appointments Dataset" Chart: Will Chase/Axios

It's harder now for presidents to win Senate confirmation for their Cabinet picks, an Axios data analysis of votes for and against nominees found.

Why it matters: It's not just Neera Tanden. The trend is a product of growing polarization, rougher political discourse and slimming Senate majorities, experts say. It means some of the nation's most vital federal agencies go without a leader and the legislative authority that comes with one.
