Key Market Challenges

Lower Energy Density Compared to Lithium-Ion Batteries

One of the primary challenges facing the Global Aqueous Battery Market is the lower energy density of aqueous batteries compared to lithium-ion counterparts. Energy density, measured in watt-hours per kilogram (Wh/kg), determines how much energy a battery can store relative to its weight. Lithium-ion batteries typically offer an energy density of 150–250 Wh/kg, while most aqueous batteries currently range between 30–100 Wh/kg. This substantial difference limits their applicability in sectors where high energy storage per unit weight is crucial, such as electric vehicles (EVs), portable electronics, and aerospace applications.

The lower energy density of aqueous batteries is primarily due to their water-based electrolyte composition, which has a lower electrochemical stability window than the organic electrolytes used in lithium-ion batteries. This means aqueous batteries operate at a lower voltage, reducing their overall energy output. Consequently, industries that require compact and lightweight energy storage solutions continue to favor lithium-ion technology despite its higher cost and safety risks.

Another drawback of lower energy density is the increased size and weight required to achieve the same energy capacity as lithium-ion batteries. For example, a grid-scale energy storage facility using aqueous batteries would need significantly larger and heavier battery systems compared to a lithium-ion-based facility with the same storage capacity. This can increase space requirements, transportation costs, and installation complexity, making aqueous batteries less attractive for applications with spatial constraints.

While research is ongoing to improve the energy density of aqueous batteries—such as developing advanced electrode materials, optimizing electrolyte compositions, and utilizing hybrid battery chemistries—progress has been gradual.
