Revolutionizing Sodium-Ion Batteries
Researchers have made significant strides in developing sodium-ion oxide cathodes using a unique core-shell structure. These particles feature a nickel-rich core encased in a cobalt and manganese-rich shell. The manganese-rich outer layer is crucial for maintaining structural integrity during the charging and discharging cycles, while the nickel core enhances energy storage capacity.
Despite their promise, these sodium-ion batteries faced challenges, particularly the gradual decline in energy storage capabilities over time. Investigations revealed that these issues stemmed from cracks forming within the particles due to stress at the interface of the core and shell. Remarkably, further analysis indicated that these cracks originated deep within the particles, contrary to previous assumptions.
To combat this problem, scientists employed advanced synchrotron technology and one of the world’s top supercomputers, resulting in innovative ways to create crack-resistant cathodes. The breakthrough change in the heat treatment process led to the production of robust particles that maintained their energy storage capacity through 400 cycles.
The potential for future sodium-ion batteries is considerable, offering low costs, longevity, and energy densities similar to those in current lithium-ion technologies, which could significantly benefit electric vehicles. Looking ahead, researchers plan to enhance sustainability by aiming to eliminate nickel from the cathodes, further pushing the boundaries of battery technology.
