New aluminum batteries could be the low-cost alternative to lithium-ion we’ve all been waiting for

By On Aug 28, 2022

The price of lithium-ion batteries has been rising steadily since 2020. The price of lithium alone has skyrocketed by about 500% in the past year. Other minerals used in lithium-ion batteries have also become expensive, and many energy experts suggest that the price of such batteries is also likely to rise in the coming years. Therefore, lithium-ion batteries may no longer be a suitable choice for medium- and large-scale energy reserve systems that store renewable energy.

An international team of researchers has devised an alternative to Li-ion technology. They claim to have developed an inexpensive battery system from aluminum and sulfur. Both are abundantly available on Earth. In fact, aluminum ranks second in availability on the market and first among the most abundant metals in the crust of our planet. Also, compared to lithium-ion batteries, the new batteries could prove to be a more feasible option for powering homes and businesses.

Although lithium-ion batteries are currently the most popular energy storage systems on the planet, powering almost everything from smartphones to smoke detectors to electric vehicles (EVs), due to Despite its high cost and limited supply, the new battery system has many possibilities. to replace Li-ion in some industries, according to the researchers.

The merits of aluminum-sulfur batteries

A battery system contains electrodes (cathodes and anodes, the first is the positive end and the second is the negatively charged end) and an electrolyte (a conductive medium that allows the exchange of ions in order to charge and discharge between the two ends). . The new battery system is composed of molten chloro-aluminate salt as electrolyte and sulfur and aluminum as electrodes.

The researchers decided to go with these chemical elements because they form a combination of cheap and readily available battery cells. They also claim that compared to lithium-ion batteries that come with a flammable electrolyte, aluminum-sulfur batteries could prove to be much safer. Since the electrolyte used in the new batteries has a low melting point, it is better equipped to prevent any incidents of battery fires and short circuits resulting from the natural build-up of dendrites, metal spikes that often form on electrodes of lithium ion batteries. during loading and unloading.

The proposed battery architecture could be useful for energy storage and backup system for homes, medium-scale businesses, and electric vehicle charging stations. Explaining further, one of the study’s authors and professor emeritus of materials chemistry at MIT, Donald Sadoway said in a statement:

“When electric vehicles become common enough on the road that multiple cars want to charge at the same time, as is the case with gas pumps today, if you try with batteries and want fast charging, the amperages are so high that they don’t have that amount of “amperage (maximum electric current that can safely flow through a system) on the line that feeds the installation”. He further added, “So having a battery system like this to store energy and then quickly release it when needed could eliminate the need to install expensive new power lines to serve these chargers.”

The new battery system also performed well in load stress tests, retaining its performance over hundreds of charge cycles. With this in mind, the cost per cell of an aluminum-sulfur battery could be about 83% less than a lithium cell. These tests also showed that aluminum-sulfur battery cells could be charged in just over a minute with a capacity per weight equal to that of conventional lithium-ion batteries. When charged in just six minutes, the charge capacity was 25% greater than that of lithium-ion.

But is this a miracle product? Far. Its biggest limitation is that it needs 90°C, which is almost the boiling point of water, to work. As such, aluminum and sulfur batteries require special insulation and anti-corrosion measures.

Limitations and future of the new battery architecture

Currently, the proposed battery system can easily meet the energy storage demands of activities that require tens of kilowatt-hours of energy as backup. However, the technology is not yet powerful enough to support megawatt-scale power needs. Professor Sadoway has co-founded a company called Ambri to bring this exciting technology to market.

The researchers are currently planning to conduct further tests to further test the scalability and stress resistance of the aluminum-sulfur battery system.

The study is published in the journal Nature.
