China’s New EV Battery Survives 36-Ton Tank Smash in Real-World Test That Leaves Experts Speechless and Worried

In a groundbreaking display of innovation and engineering prowess, a Chinese automobile company has unveiled a revolutionary EV battery that defies conventional safety standards. This remarkable battery, developed with high-quality and flexible materials, survived the seemingly impossible task of withstanding the crushing weight of a 79,200-pound (36-ton) tank. This feat not only highlights the advanced safety technology employed but also sets a new benchmark for battery resilience in extreme conditions. As the world moves toward more sustainable transportation solutions, such technological breakthroughs are crucial for ensuring the safety and reliability of electric vehicles.

EV Battery Endures Extreme External Impact

The demonstration was nothing short of spectacular, as the battery packs emerged unscathed, showing no signs of fire, explosion, or thermal runaway. Simulating a real-world scenario where a vehicle’s battery might face severe external impact and compression, the test involved a 79,200-pound tank repeatedly driving over the battery pack. This intense pressure is 1.8 times higher than China’s standard safety requirements for EV batteries, making the battery’s survival all the more impressive.

The manufacturer confirmed that the battery pack maintained its structural integrity without any bulging, leakage, or fire. This was verified through a detailed onsite inspection, which revealed that the energy storage device endured compression forces well beyond the new national standards. Such resilience ensures that the battery can withstand extreme conditions, reassuring consumers about the safety of the electric vehicles equipped with this technology.

Aegis Gold Brick Battery Offers Minimal Heat Generation

This test marked the first time a battery’s safety was demonstrated using such an unconventional method. Traditionally, battery safety is tested through crash simulations, lifecycle tests, or puncture tests. However, using a 79,200-pound tank to test the Aegis Gold Brick battery’s resilience was a unique and bold approach.

The Aegis Gold Brick battery, specifically designed for the Geely Galaxy E5, is engineered to generate minimal heat, have increased thickness, and exhibit low internal resistance. During the test, the tank rolled over both individual battery cells and a group of ten cells, yet the battery remained intact. This innovative testing method underscores the battery’s ability to withstand extreme conditions while maintaining optimal performance.

High-Quality, Flexible Materials Maintain Strength

Developed with high-quality and flexible materials, the battery incorporates an aluminum oxide heat-resistant coating to prevent cell rupture and thermal runaway. This robust design enables the battery to meet and exceed new safety standards set by China’s Ministry of Industry and Information Technology, which will take effect in July 2026.

Reports indicate that the Geely Aegis Gold Brick battery has undergone 36 rigorous test scenarios, surpassing the 24 tests required by current Chinese national standards. Impressively, 23 of these tests exceed China’s existing safety requirements. The battery’s design includes four energy-absorbing cross-sections and a 0.1-inch-thick (2.6 mm) “sandwich” structure bottom plate, enhancing safety through liquid-electric separation and electrical isolation.

Setting New Standards for Battery Safety

The Galaxy E5, equipped with this innovative battery, has consistently demonstrated excellent performance in extreme high-temperature tests and comprehensive safety trials conducted by the China Automotive Technology and Research Center (CATARC). The vehicle has received prestigious certifications, including the NESTA six-dimensional electrical safety certification and five-star safety ratings from Euro NCAP and ANCAP.

The company’s decision to open its battery safety patent portfolio to the wider industry reflects its commitment to advancing battery technology and enhancing safety standards globally. By sharing these innovations, Geely aims to foster collaboration and drive further advancements in the EV industry, ultimately benefiting consumers and promoting sustainable transportation solutions worldwide.

The successful demonstration of the Aegis Gold Brick battery’s resilience under extreme conditions is a testament to the remarkable engineering and innovation in the EV industry. As electric vehicles continue to gain popularity, ensuring the safety and reliability of their batteries becomes paramount. This groundbreaking achievement raises an intriguing question: How will such advancements in battery technology influence the future of electric vehicle safety standards and consumer confidence?
