A National Science Foundation-funded research has discovered the root cause of why lithium metal batteries fail -- bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as "dead" or inactive lithium that the battery can no longer access. The discovery challenges the conventional belief that lithium metal batteries fail because of the growth of a layer, called the solid electrolyte interphase (SEI), between the lithium anode and the electrolyte. The researchers made their discovery by developing a technique to measure the amounts of inactive lithium species on the anode -- a first in the field of battery research -- and studying their micro- and nanostructures. The findings could pave the way for bringing rechargeable lithium metal batteries from the lab to the market.

Preparations continue in Surfside, Fla. for the demolition of a portion of the Champlain Towers South still standing after much of the building collapsed in the early morning hours on June 24.

Miami-Dade County Mayor Daniella Levine Cava told reporters on Sunday that bringing down the remainder of the collapsed condominium in a controlled fashion is crucial to the safety of search and rescue teams.

Those teams have paused their work so demolition can take place. Levine Cava said officials are still unsure of a specific time that the demolition will occur.

"Our top priority is that the building can come down as soon as possible — no matter what time that occurs — and safely as possible," Levine Cava said at a morning news conference.

The number of confirmed dead from the collapse remains at 24. The number of people unaccounted for remains at 121.

Preparations for the demolition come as Tropical Storm Elsa is tracking towards southern Florida. The storm is expected to hit the area Monday and Tuesday.

The instability of the building could be made worse by the storm, which is expected to bring strong winds and rain at the beginning of the week. Mayor Levine Cava said that as soon as the demolition has occurred, search and rescue efforts are expected to resume.

Ahead of Elsa's arrival in Florida, Gov. Ron DeSantis issued a state of emergency Saturday for 15 counties, including Miami-Dade.

On Sunday, he expressed optimism that the Surfside area may be spared from the worst of the storm.

"We could see some gusts, but it has tracked west over the last day and a half — more so than the initial forecast," he said. "So, we'll just keep watching that."

SURFSIDE, Fla. — Crews used explosives late Sunday night to demolish the remaining structure at Champlain Towers South in Surfside, Fla.

The heavily damaged condo building was knocked down at about 10:30 p.m. Eastern time.

The targeted blast caused the tower to fold and crumble, sending a large plume of dust and debris over a section of the beachside community. A crowd watching from a distance prayed as the building came down.

Before the structure was leveled, Miami-Dade County police urged residents who live nearby to remain indoors and shelter in place.

Miami-Dade County officials said removing the tower was an essential step so search and rescue teams could resume scouring the rubble pile for victims of the disaster.

Officials suspended recovery efforts on Saturday because of concerns about the danger posed by the unstable building.

"It will be safe to resume the search activities very shortly after the blast and that's when we'll resume it," said Miami-Dade County Mayor Daniella Levine Cava at a press conference Sunday evening.

Demolition of the tower was also accelerated because of Tropical Storm Elsa, which could hit South Florida with high winds and heavy rains as early as Monday.

Search efforts had been ongoing since the morning of June 24, when much of the 12-story condo complex suffered a "progressive collapse" and dozens of apartments were reduced to rubble in a matter of seconds.

The number of confirmed dead from the disaster remains at 24, with the number of people unaccounted for at 121.

Rep. Debbie Wasserman Schultz, D-Fla., told reporters Sunday the demolition of the remaining tower added to the sorrow for families who lived in the complex, destroying homes and possessions.

"So often demolitions of buildings are a spectacle, it's almost like a show," Schultz said. "This demolition is a tragic situation."

Local officials assured former residents and the public that everything possible had been done to rescue pets left behind in the structure.

"Folks can be comfortable we're not leaving anyone behind, including our beloved pets," Surfside Mayor Charles Burkett told reporters.

Multiple investigations are already underway into the cause of the collapse.

Documents acquired by NPR from an anonymous source show the condo association's board received warnings from an engineering firm beginning in 2018 that the structure needed extensive repairs.

A memo sent by the association to Champlain Towers South residents ahead of a May 2021 board meeting acknowledged the "desperate needs of the building."
