For the proof-of-concept, the cells were manufactured to be larger than necessary to avoid unnecessary costs and lengthy manufacturing processes at this early stage. Sodium-ion intercalation batteries—i.e., Thus, insertion/deinsertion of sodium ions in a host material is much more difficult than that of lithium ions.

Researchers at Ohio State University (OSU) have demonstrated the concept of a potassium-air (K?O V), which contributes to the low rechargeability. Potassium, an alkali metal similar to lithium (and sodium) can be used in a rechargeable battery. For comparison, they built a Li?O Credit: ACS, Ren and Wu.

Our concept has the following advantages: Compared to carbon dioxide, solid bicarbonates are easy to handle and highly soluble in aqueous media (96 g L -1 NaHCO 3. Most importantly, after full conversion of the formate, the bicarbonate solution may be recharged with hydrogen to close the cycle. at 20 °C in H 2 O).
