Differences Between Flow Batteries and Lithium Ion Batteries. In the quest for better energy storage solutions, flow, and lithium-ion batteries have emerged as two of the most promising technologies. Each type has its own unique set of characteristics, advantages, and limitations.
Let''s dive into the advancements in battery technology between Vanadium Redox Flow Batteries (VRFBs) and lithium-ion batteries, exploring how each stacks up in terms of expansion flexibility, energy density, safety, lifespan, cost-effectiveness, and market growth.
On every count, nanoelectrofuel flow batteries appear to beat lithium-ion batteries for use in EVs and larger systems.
Ok, so you are probably wondering two things: am I going to need a periodic table to finish this post, and why does this all matter?This matters because, unlike Li-ion batteries, flow batteries have liquid electrolyte stored in external tanks rather than in each battery cell (see figure). Since the energy-carrying electrolyte is physically separate from the power-producing stacks, much like an automobile with an internal combustion engine and a separate fuel tank, flow batteries have their energy and power decoupled. If you want a longer duration battery, buy a bigger gas tank, not a bigger gas tank and a bigger engine, which is required in Li-ion batteries.
Unlike an automobile with its engine, however, a flow battery can recharge the electrolyte after discharge (have you ever seen an engine run in reverse to produce gasoline and air?). And unlike Li‑ion batteries, the electrolyte gets charged and discharged by flowing through all the cells and stacks at the same time, so there is one common state of charge (SoC) rather than many individual SoC''s for each individual cell. This, in turn, means that cell and stack balancing is not required.
So, do all these differences lead to lower degradation, improved safety, and longer-duration capability compared to Li‑ion batteries? Well, you know what they say, the devil is in the details and the proof is in the pudding.
The Devil and the PuddingFirst, let''s dive into the details behind the claims that flow batteries have lower degradation, improved safety, and are better for long-duration applications. Then we will see if there is proof to support these claims. The following list highlights claims about flow battery advantages and disadvantages compared to Li-ion systems and if each has a significant impact (or supporting data) to substantiate.
Flow battery manufacturers claim that throughput-dependent degradation is very low, giving flow batteries a distinct advantage over Li-ion batteries that degrade more rapidly.
Time-dependent degradation (calendar fade) in flow batteries is near-zero.
Flow batteries can increase their energy output (kWh) without increasing their power output (kW), which cannot be done in Li-ion batteries and saves significant cost on long-duration (i.e. multi-hour) applications.
Flow batteries have a lower fire risk than Li-ion batteries.
Flow batteries are safer to service than Li-ion batteries.
Flow batteries have simpler monitoring and controls and less degradation than Li-ion batteries because no cell-to-cell or stack-to-stack balancing is required.
Flow batteries have more accurate measurement of SoC, allowing for wider operating range of the battery and less degradation than Li-ion batteries.
Flow batteries have a complex balance of plant that requires pumps, plumbing, and electrolyte tanks for electrolyte management, which add capital costs and operation and maintenance requirements.
Flow battery system mass is relatively high, which means they are more attractive for stationary applications, where Li-ion systems are more versatile.
Flow batteries have a lower dc round-trip efficiency (RTE) than Li-ion systems.
Flow batteries are far behind Li-ion batteries in market penetration and diversity of markets.
As a final consideration, many players in the flow battery industry have recently stumbled, including Imergy, Aquion, and ViZn, and it is likely that only a few will be able to capitalize on the potential advantages of flow batteries. Whether it is reviewing performance history, design details, company leadership, or financials, DNV is well positioned to help identify risks and navigate design considerations to make the best-informed decision about this nascent technology.
Wind and solar photovoltaic are widely deployed, carbon free energy sources. But they are highly intermittent, and coping with this irregular power flow has traditionally required peaker plants usually powered by natural gas, oil or coal.
Grid-scale battery storage promises to eliminate the need for the peaker plants, and multiple battery projects have been deployed around the world. Which battery technology is best for this application, however, is still at issue.
