Increasing the size of cylindrical lithium-ion batteries (LIBs) to achieve higher energy densities and faster charging represents one effective tactics in nowadays battery society. A systematic understanding on the size effect of energy density, thermal and mechanical performance of cylindrical LIBs is of compelling need.
Pegel et al. [33, 34] proposed a thermo-electrical-electrochemical framework based on the 4680 cell to study the cell size influence on the fast-charging behavior of large-format cylindrical LIBs. All those explorations lead to a consensus that a comprehensive understanding upon the size effect of batteries is desired.
Now, MIT researchers have demonstrated a modeling framework that can help. Their work focuses on the flow battery, an electrochemical cell that looks promising for the job—except for one problem: Current flow batteries rely on vanadium, an energy-storage material that's expensive and not always readily available.
That arrangement addresses the two major challenges with flow batteries. First, vanadium doesn't degrade. “If you put 100 grams of vanadium into your battery and you come back in 100 years, you should be able to recover 100 grams of that vanadium—as long as the battery doesn't have some sort of a physical leak,” says Brushett.
