New Chinese battery: 2000 km range included

New Chinese battery: 2000 km range included

There have been several full-blown announcements about a solid-state battery soon to be available in recent years. But no concept has yet reached series production or even the electric fleet. Chinese startup Talent New Energy has so far only offered batteries containing semi-solid electrolytes. They have at least received awards from experts. The developers are now showing off a powerful prototype that should offer a lot more.

The new cell uses a lithium metal cathode and is expected to have a charging capacity of 120 amps and a power density of 720 watts per kilogram of battery weight. For comparison: the company's superior semi-solid batteries have so far managed to achieve a maximum of 400-500 Wh/kg. The Qilin battery from battery giant CATL can be found in this area (see photo gallery). Thanks to ultra-thin composite oxide layers, Talent New Energy's third generation no longer contains any liquid components in the electrolyte and is therefore temperature safe and capable of extremely fast charging.

The Chinese have not yet revealed much about the technical structure of the new super cell. However, Talent New Energy mentions “high capacitance electrode materials.” This means not only the cathode of the lithium metal (i.e. the negative electrode), but also the anode (i.e. the positive electrode). This should consist of lithium-rich manganese materials. When it comes to describing the structure, things get a little fuzzy. The “integrated casting process” aims to ensure a particularly effective ion and electron transport network in the flexible layer materials in the electrolyte. Unfortunately, this general interpretation still holds.

Whether and when this solid-state chemistry can be transferred to series production also remains an open question. However, if this happened, it would indeed be possible to achieve enormous ranges with such high power densities. A modern electric car battery can, at least mathematically, travel 2,000 kilometers between two charging stations. But the big question remains: when will this happen?

Conclusion

Chinese startup Talent New Energy has introduced a new battery cell with an ultra-high energy density of 720 Wh/kg. This means that a modern electric car should have a range of about 2,000 kilometers. But it remains to be seen whether the solid-state battery will enter series production or not.
