A prototype solid-state battery developed by UK startup Ilika has made a significant breakthrough in electric vehicle (EV) technology. The Goliath P1 battery successfully passed the nail penetration test, which simulates a catastrophic incident that can lead to thermal runaway in traditional lithium-ion batteries.
The test involved piercing the battery with a nail, causing it to reach extreme temperatures of 1112°F (600°C). However, the Goliath P1 remained safe and stable, avoiding hazardous swelling, rupturing, explosion, or fire. The external temperature stayed below 176°F (80°C), demonstrating its superior thermal management.
This achievement has significant implications for the EV industry, as solid-state batteries are seen as a promising technology for safer and more efficient electric vehicles. The inherent safety advantage of these batteries could lead to simpler battery pack designs, reducing the need for extra protective packaging.
Ilika’s CEO, Graeme Purdy, stated that the company has designed solid-state cells intended to provide a safer alternative to high-energy lithium-ion batteries. With plans to have a mass-producible version available by 2025, Ilika aims to establish a pilot facility for megawatt-scale production using existing lithium-ion battery manufacturing infrastructure.
The success of the Goliath P1 prototype highlights the rapid progress being made in solid-state battery technology. This breakthrough has the potential to transform the EV industry and support a more sustainable future.
