Series production of SVolt's new nickel-manganese batteries (NMX) has begun on schedule. SVolt made the announcement at a ceremony in Jintan, China.

Already in January 2021, pilot production with 10 tons of cobalt-free cathode material was successfully completed at the battery cell factory in Jintan. SVolt has now been mass-producing the cobalt-free cathode material since April.

NMX batteries in Great Wall electric car

SVolt is initially producing two sizes of NMX batteries (115 Ah and 226 Ah), which are 75 percent nickel and 25 percent manganese. Thanks to the complete elimination of the heavy metal cobalt, one of the most expensive and controversial cathode elements, and a lowered nickel content, SVolt's cobalt-free NMX cells are not only more sustainable, but also about 5 percent less expensive than classic NCM battery cells, according to the company. As a result, they address the broad mid-range market in particular.

With the help of the new technology, SVolt has also succeeded in significantly improving the cycle aging as well as the calendar aging of the NMX cells compared to conventional NCM battery cells. This means that more than 2500 charging cycles can be achieved.

Great Wall Motors' ORA Cherry Cat is the first electric car to benefit from SVolt's NMX batteries. From the end of 2023, the novel batteries will also be produced at the planned plant in Saarland for the European market.
