2024 June 27th, Hangzhou. Geely Auto Group have released their latest generation of self-developed lithium iron phosphate short blade battery that offers best in class battery life, charging speed – and ultimate safety. Geely Auto’s New Short Blade EV Battery Technology will become the new benchmark for EV batteries with industry leading safety, compact size, higher energy density, better volume utilization, and increased flexibility in accommodating different pack designs.

New Standards for Safety

The New Short Blade EV Battery Technology uses a high-strength, high-thermal stability, high-heat-resistant diaphragm, with a highly stable separator paired with safe electrodes resulting in higher energy density and safety. In addition, Geely Auto has applied its self-developed Self-Fusing technology on the electrode surfaces to block short circuits in event of accidents. If the battery cell is punctured during extreme shock, an aluminum foil layer will fuse into the battery diaphragm to create an insulating layer, preventing short circuits and thermal runaway events.

To date, the standard automotive test for EV battery safety performance is the single needle puncture test, however Geely Auto has been testing the New Short Blade EV Battery Technology with eight simultaneous puncture needles, which significantly increase the amount of damage received in extreme crash situations. During testing, it was simultaneously punctured by eight steel needles in unison, each with a diameter of 5mm and left to stand for 1 hour with zero ill effects.

In addition, the New EV Battery Technology underwent a 5.8mm (5.8×42mm) infantry rifle bullet penetration test, with no thermal ignition events.
