“On the cathode side, Prussian blue, a non-toxic dye, is used in a state completely mixed with sodium ions,” Professor Hölzle explains further. It can therefore be assumed that materials research has been a success here. CATL has probably been able to significantly improve the amorphous carbon on the anode side, the so-called hard carbon, in terms of irreversible losses and fast-charging capability. Hölzle, who holds a doctorate in electrochemistry and worked for BASF for a long time and internationally before joining ZSW, continues: “For example, 20 per cent of the capacity has so far been lost during the very first charge,” says Hölzle. “The CATL developers must have succeeded in solving the known problems of sodium-ion cells, which are not new in principle,” explains Markus Hölzle. The next generation is expected to exceed 200 Wh/kg CATL has yet to say when. For example, CATL claims a comparatively low gravimetric energy density of 160 Wh/kg. It mixes lithium and sodium-ion cells to compensate for first-generation weaknesses. Dr Markus Hölzle of ZSW (Center for Solar Energy and Hydrogen Research Baden-Württemberg) to come to a realistic assessment of sodium-ion cells.ĬATL itself gets specific in the presentation: the Chinese company shows the actual cell and a battery system. Therefore, our contributor talked to the battery professionals of P3 Automotive and Prof. And indeed, the replacement of the alkali metal lithium by the next element of this main chemical group would be the opportunity for further clear cost reduction.

(CATL) has made a “breakthrough” with the establishment of basic production for sodium-ion cells, according to its own reading. The potential is huge!Ĭontemporary Amperex Technology Ltd. Schwarzer evaluated the technology by speaking to battery experts from P3 Automotive and Prof. What are the advantages and disadvantages of replacing lithium? Christoph M.
