No, a single battery cell cannot truly charge and discharge simultaneously—but advanced systems create this illusion. Imagine your phone plugged in while gaming: it seems
Vanadium redox flow batteries are expected to be the most commonly deployed type of flow battery, primarily because of their ability to be charged and discharged without degrading.
Flow Battery ClassificationsAdvantages and DisadvantagesFuture DirectionsBibliographyMost redox flow batteries consist of two separate electrolytes, one storing the electro-active materials for the negative electrode reactions and the other for the positive electrode reactions. (To prevent confusion, the negative electrode is the anode and the positive electrode is the cathode during discharge. It is to be noteSee more on knowledge.electrochem SolarReviews

There are both benefits and drawbacks to charging and discharging a battery at the same time. On the positive side, it can help in reducing downtime for critical systems and
Capacitors have fast sub-second response times, deep discharge capability, and can deliver high power but for only short times, so these devices are more suitable for power quality

A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane. Ion transfer inside the cell (accompanied by current flow through an external circuit) occurs across the membrane while the liquids circulate in their respective spaces.
Since these energy sources are intermittent, flow batteries can store excess energy during times of peak generation and discharge it when demand is high, providing a stable
No, a battery can''t be charged and discharged at the same time. If a battery is connected to a charger delivering 1 A and a load drawing 3 A, then the battery will be discharged at 2 A.
Redox reactions occur in each half-cell to produce or consume electrons during charge/discharge. Similar to fuel cells, but two main differences: Reacting substances are all in the liquid phase.

The main difference between flow batteries and other rechargeable battery types is that the aqueous electrolyte solution usually found in other batteries is not stored in the cells around the positive electrode and negative electrode. Instead, the active materials are stored in exterior tanks and pumped toward a flow cell membrane and power stack.
In contrast with conventional batteries, flow batteries store energy in the electrolyte solutions. Therefore, the power and energy ratings are independent, the storage capacity being determined by the quantity of electrolyte used and the power rating determined by the active area of the cell stack.
Flow batteries can release energy continuously at a high rate of discharge for up to 10 h. Three different electrolytes form the basis of existing designs of flow batteries currently in demonstration or in large-scale project development.
There is no simultaneous charging and discharging going on. Draw out the circuit and follow the currents. You can conceptualize the above example as 1 A charging the battery and 3 A discharging it, but the battery sees the sum. Again, draw a diagram and it should be more clear. Handwaving makes everything difficult to understand.
