Scientists from the University of Chicago and the University of California San Diego have come together to create a groundbreaking battery combination. This innovative research collaboration has resulted in the world’s first anode-free sodium solid-state battery, a significant breakthrough in power storage technology.
Previous attempts at combining sodium, solid-state, and anode-free batteries have failed, making this achievement all the more remarkable. “Sodium solid-state batteries are usually seen as a far-off-in-the-future technology,” said Grayson Deysher, the first author of the research paper and a doctoral candidate at UC San Diego.
The traditional lithium-ion batteries commonly used today rely on costly and hard-to-gather materials, such as lithium, as well as liquid electrolytes that pose fire risks. In contrast, the anode-free sodium solid-state battery addresses these concerns on multiple fronts.
Firstly, sodium is an abundant and cost-effective material. While lithium is found in the Earth’s crust at a concentration of 20 parts per million, sodium’s availability is at a staggering 20,000 parts per million. Furthermore, sodium can be sourced from abundant seawater, making it an environmentally friendly choice.
Secondly, the solid-state design of these batteries eliminates the need for liquid electrolytes, enhancing both power and safety. The researchers achieved this by using a unique “solid that flows” current collector made from aluminum powder. This unconventional approach resolved operational issues and allowed for low-cost and high-efficiency cycling.
Lastly, removing the anode from the battery reduces the amount of expensive materials required, making it more affordable without compromising energy storage capacity. This breakthrough in chemistry has significant implications for electric vehicles and other technology that rely on high-performance batteries.
By utilizing abundant materials and implementing improved chemistry, the research team has successfully created a more affordable, environmentally friendly, safe, and powerful power storage solution. These qualities are essential for the transition to cleaner and renewable energy sources, combating heat-trapping air pollution and promoting human health.
The quest for better batteries is well underway, with a record 1.2 million electric vehicles sold in the U.S. last year alone. Each electric vehicle contributes to reducing thousands of pounds of air pollution compared to traditional gasoline-powered cars. Additionally, electric vehicle owners benefit from significant savings by eliminating fuel costs.
The Chicago/San Diego research team is currently seeking patents for this groundbreaking invention, which has demonstrated stable operation through hundreds of cycles during testing. As Professor Y. Shirley Meng from the University of Chicago stated, “We need more batteries, and we need them fast” to accomplish the goal of decarbonizing our economy.
This anode-free sodium solid-state battery represents a significant leap forward in power storage technology, bringing us closer to a cleaner and more sustainable future.
