Nonflammable battery

Nonflammable battery developed by scientist…

Researchers at the Swiss Federal Institute of Technology (ETH) in Zurich have announced they successfully tested a new solid-state battery model that can handle higher temperatures and improve fire safety compared to older Lithium-Ion batteries.

  • Scientists have developed a lithium-ion battery that consists entirely of solid compounds.
  • And is non-flammable, even at very high temperatures.
  • Lithium-ion batteries store a lot of energy in a small space.
  • It’s making them the energy source of choice for mobile electronic devices.
  • Such batteries Today are using in mobile phones, laptops, e-bikes and electric cars.

About Battery:-

  • In conventional lithium-ion batteries as well in most other batteries, the positive and negative poles – the two electrodes – are made of solid conductive compounds; charges move between these electrodes in a liquid or gel electrolyte.
  • If such a battery is improperly charged (overcharging) or left sitting out in the Sun, the liquid can ignite or the gel can swell up.
  • This is not the case with solid-state batteries, which are currently in development in research laboratories worldwide.

Jennifer Rupp, Professor at ETH Zurich said ,

“Solid electrolytes do not catch fire even when heated to high temperatures or exposed to the air,” 

  • Researchers developed an improved electrode-electrolyte interface.
  • The scientists tempered the battery at 100 degrees Celsius.
  • Its naver been before.

New model removes fire safety risk

The Lithium-Garnet compound replaces classic Lithium-based salts and organic solvents used with Lithium-Ion and other types of batteries in the past.

There have been many cases where these liquid and gel substances have heat over their normal temperature, expand, and then explode or catch  fire due to the rising temperature inside the battery.

The new solid-state compound has the highest known conductivity for Lithium ions, allowing the charging and discharging process to occur, while any heat expansion takes place using the space made available via the pores.

As such, the battery can function properly at higher temperatures, which classic models couldn’t reach.
