Zeekr Launches A Battery To End All Batteries, The 800V Golden Battery
The Zeekr 800V Golden Battery is able to do things no other battery can do
Chinese electric vehicle (EV) maker Zeekr, a brand under the Geely umbrella, has officially launched a new self-developed lithium iron phosphate (LFP) accumulator called Golden “Brick” Battery during the Zeekr Power Day and it is going to put every single other battery out of business with the things it can do.
Zeekr claims that this Golden Battery is super safe, performing extreme testing such as keeping it at extreme cold (-45°C) for 8 hours, and even throwing it into a 1000°C fire, and installing it back in the car, showing it still works. While EV battery fires are a constant fear, this battery does mitigate this quite a bit.
Moreover, Zeekr also claims that the 800V Golden Brick Battery is the world’s first mass-produced LFP battery with volume utilization over 80 percent. The mass production started today, and the Zeekr 007 sedan will be the first vehicle to use it. The 007 will launch on 27 December 2023.
The battery has 83.7 percent volume utilization thanks to an optimized compact “sandwich structure,” ultra-thin separators, and an integrated tray design. For comparison, in June 2022, CATL unveiled its Qilin battery with NMC chemistry and CTP (cell-to-pack) technology.
It also has a record-breaking utilization of 72 percent and 255Wh/kg energy density. Back in 2019, the volume utilization of CATL’s first module-less CTP battery was only 55 percent. Today, about 66 percent volume utilization is a standard for LFP batteries.
On top of that, the Zeekr Golden Brick’s peak charging power is 500kW, and the maximum charge rate is 4.5C. Between 10 percent and 80 percent, the battery can charge 500 km in 15 minutes. At -10 °C, the fast charging speed increases by 25 percent. It is also capable of 16C short burst discharge in 3 seconds.
The battery’s body is also covered with 4000V high voltage-resistant gold-colored insulation film, increasing resistance by 27 percent. The whole pack is also waterproof, reaching an IPX level of 8. Zeekr also dragged it through the mud for 3KM then installed the battery back into the car and it still functioned properly.
While this is no doubt an amazing achievement, it still wasn’t enough for Zeekr as the brand sent the 22-ton roller to drive over it and let the 710kg battery fall 10 metres from the crane, showing no fire, smoke, or exploding. Well, it seems all other EV batteries have plenty of catching up to do.
