A reaction engineering approach to non-aqueous battery lifetime
Longer lifetime will improve the economic and environmental costs of Li-ion batteries. Predicting and controlling lifetime requires better understanding of chemical side reactions. Here, we argue that battery side reactions are essentially a problem of catalytic selectivity. In this reaction engineering context, we discuss the advantages and …

What Can Replace Battery Electrolyte?
Sulfation can shorten the life of a battery because it interferes with the normal operation of the cells. Under normal conditions, sulfuric acid in the electrolyte solution is absorbed into the lead plates as the battery discharges power. It is then released back into the electrolyte solution as the battery charges.
Semi‐solid flow battery and redox-mediated flow battery: two …
Despite that the use of low-cost microporous separator reduces the upfront cost of the reactor per unit of area, the operating current density (mA cm −2) and the specific power (W cm −2) will determine whether the final power cost for SSFBs is lower than that of conventional RFBs.That is, power capacities directly determine the size of the …
