Solid-state EV battery defeats 1112°F thermal runaway, withstands extreme heat
The Goliath P1 remained safe and stable, avoiding the hazardous swelling, rupturing, explosion, or fire typically associated with traditional lithium-ion battery failure.
Aprototype solid-state battery, named the Goliath P1 and developed by UK startup Ilika, has made waves in the electric vehicle (EV) industry due to its significant benefits and implications. The battery achieved a major breakthrough by passing an important safety test known as the nail penetration test.
This test simulates a catastrophic incident that often leads to dangerous thermal runaway—a condition in which traditional lithium-ion batteries, which use liquid electrolytes, can explode or catch fire.
During this test, the Goliath P1, which uses a solid electrolyte, stayed at a temperature below 176°F (80°C). This is much lower than the 1112°F (600°C) often reached in thermal runaway events associated with lithium-ion batteries.
The company in a press release said :
In the nail penetration tests the P1 cells neither exploded nor caught fire, with external temperatures remaining below 80°C.
Furthermore, the Goliath P1 showed none of the hazardous swelling, rupturing, explosion, or fire that typically occur when traditional lithium-ion batteries fail.
Solid state batteries to boost EVs
Dr. James Robinson, leader of the UK Safebatt Project, which focuses on improving EV battery safety, expressed his excitement about these results.
Dr. James Robinson, leader of the UK Safebatt Project remarked:
While there is still further testing to be undertaken, there seems to be an inherent safety advantage in nail penetration tests for this cell type over conventional state-of-the-art cells
Solid-state batteries are emerging as a promising technology in the quest for safer and more efficient electric vehicles. As the world moves towards achieving NetZero emissions, EVs are expected to be essential in this transition.
Solid-state batteries, known for their improved safety and high energy density, have the potential to transform the EV industry.
The inherent safety of solid-state batteries, as shown by Ilika’s successful nail penetration test, addresses the significant concerns linked with conventional lithium-ion batteries
This increased safety could lead to simpler battery pack designs by reducing the need for extra protective packaging. As a result, vehicles could become lighter and safer, with a greater driving range.
