6 FAQs about [Battery solvent field scale]

Can a non-aqueous flow battery be used in organic solvents?

In regard to other non-aqueous flow batteries using organic electrolytes, there is still a long way to go before being put into official use. The modeling research can thereby be carried out in many aspects and scales. For macroscale modeling work, the performance test of full-cell or half-cell in new organic solvents is valuable.

How do we validate the force field of pure EC & PC solvents?

To further validate the force field, we calculate the density, liquid–vapor surface tension and viscosity of pure EC, PC, DMC, and DME solvents with the TraPPE force field using the parameters given in Table 1 and compare them with the corresponding experimental values. The results are shown in Table 2.

Can a flow cell be scaled to a stack-scale battery?

More significantly, there exist many issues when scaling up the flow cell toward the stack-scale batteries. In engineering applications, the stack consists of several flow cells that have enlarged active areas, as shown in Fig. 1 d.

How can numerical modeling help a battery stack?

In the future, numerical modeling is expected to assist flow pattern optimization and provide scale-up pathways for practical applications. In addition, the scaling of flow-field-structured configuration on a graphite plate would highly increase the capital cost of a battery stack.

What makes a good flow battery solvent?

An excellent flow battery solvent should have high conductivity, low viscosity, good stability, and a wide liquid temperature range while ensuring high solubility of the solute. In reality, it is very difficult to develop such an ideal solvent.

What is a suitable electrolyte solution for lithium sulfonimide batteries?

Recent developments have empirically demonstrated that lithium TFSI (bis (trifluoromethane)sulfonimide) salts (at about 1 M concentration) in 1:1 mixtures of the organic solvents 1,2-dimethoxyethane (DME) and 1,3-dioxolane (DOL) are found to be a suitable electrolyte solution for Li/S batteries, satisfying many of the requirements , .
