Alternative battery chemistries - developments and challenges

摘要

1. The current constitutents of LIBs are "critical raw materials"; upcoming pressure on ressources 2. SIBs are a "drop-in" technology and have the potential to be cheap, sustainable, safe. 3. SIB are at higher TRL, scale-up of materials and cell production. 4. Organic electrode based on porphyrins can deliver good capacities at very high rates, for several 1000 cycles. 5. Mg-S batteries need non-nucleophilic electrolytes. A new Cl-free electrolyte shows very good performance. First full cells have been fabcricated. 6. Major issues: overpotentials, capacity degradation upon cycling (polysulfide) 7. Anionic batteries offer high theoretical capacities and a plentitude of new battery chenistries which need to be explored.
