Engineers have developed a battery that is less expensive than a lithium-ion battery

By On Aug 26, 2022

Engineers created a battery from cheap and plentiful elements that can provide low-cost backup storage for renewable energy sources.

The new architecture, which is less expensive than lithium-ion battery technology, employs aluminum and sulfur as electrode materials, with a molten salt electrolyte in between.

As the world expands its wind and solar energy facilities, there is a growing demand for large-scale, cost-effective backup systems to provide electricity when the sun goes down and the air is calm, according to ScienceDaily.

Most of these applications are still too expensive for today’s lithium-ion batteries, and alternative possibilities such as pumped hydro need a topography that is generally not accessible.

Researchers at MIT and others have invented a new type of battery that is completely built with plentiful and affordable materials, which could help fill that gap.

The new battery architecture, which employs aluminum and sulfur as electrode materials with a molten salt electrolyte in between, is detailed in Nature by MIT professor Donald Sadoway and 15 colleagues from MIT, China, Canada, Kentucky and Tennessee.

Sadoway, professor emeritus of materials chemistry at John F. Elliott, adds, “I wanted to design something better, much better, than lithium-ion batteries for small-scale stationary storage and eventually automotive use,” according to ScienceDaily. .

Lithium-ion batteries are not only expensive, they also contain a flammable electrolyte, making them unsuitable for shipping.

So Sadoway began scouring the periodic table for accessible and abundant metals on Earth that could replace lithium.

According to him, the economically dominant metal, iron, lacks the electrochemical characteristics necessary for an effective battery.

However, aluminum is the second most prevalent metal on the market and the most abundant metal on Earth. “So I said, well, let’s just create a metal bookend,” he continues.

The next step was to determine what to combine the aluminum with for the second electrode, as well as what type of electrolyte to use in the medium to transport ions back and forth during charging and discharging.

Sulfur is the least expensive of the non-metals, so it was chosen as the second electrode material. Sadoway explains that for the electrolyte, “we are not going to employ the flammable, volatile organic liquids” that occasionally cause dangerous fires in vehicles and other lithium-ion battery uses.

They analyzed various molten salts with relatively low melting temperatures — close to the boiling point of water, compared to around 1,000 degrees Fahrenheit for common salts.

The three elements they ended up with are cheap and generally available: aluminum, which is similar to supermarket foil; sulfur, which is often a waste product of industries such as oil refining; and salts. “The components are cheap and the device is safe – it cannot burn out,” explains Sadoway.

Scientists demonstrated in their tests that battery cells could withstand hundreds of cycles at extremely fast charging rates, with a predicted cost per cell about one-sixth that of equivalent lithium-ion cells.

They found that the charging rate was heavily dependent on operating temperature, with 110 degrees Celsius (230 degrees Fahrenheit) exhibiting rates 25 times faster than 25 degrees Celsius (25 degrees Celsius).

Towards a better understanding of aluminum sulfur batteries using imidazolium-based electrolytes

Due to the availability of aluminum and sulfur, aluminum sulfur batteries with ionic liquid electrolytes are viable next-generation energy storage systems, as per Sciencedirect.

However, there is now very little understanding of the discharge mechanism, which impedes their growth.

To characterize the discharge and reversibility performance of Al-S cells at different current densities, a mathematical model is constructed that takes into account the complicated electrochemical reduction of sulfide species, as well as the synthesis of the various polysulfides.

The cells revealed various Al2S3 discharge processes and precipitation paths at varying current densities.

The main problem that limited discharge performance at high current densities was the contact resistance between the composite electrode and the current collector.

The reversibility of Al-S cells based on Al2S3 precipitates is very dependent on the operating current density.

The model created will be used by other researchers to improve the electrochemical performance of sulfur aluminum batteries.
