Scientists at the University of Texas at Dallas have developed a method to significantly increase the lifespan of lithium-ion batteries by solving the problem of degradation of the LiNiO₂ cathode. Using computer modeling, they found a way to make the batteries several dozen times more durable.
The main problem with LiNiO₂ was its structural instability. During battery operation, the material underwent phase transitions and oxygen loss, leading to cracks and a decrease in capacity, especially at high voltages.
The researchers proposed reinforcing the LiNiO₂ cathode with special positively charged ions that form “pillars,” stabilizing the structure and preventing it from collapsing. This would allow the batteries to withstand more charge cycles without losing efficiency.
The researchers are currently working on prototypes and plan to produce hundreds of test batteries every week. If successful, the technology could revolutionize energy storage, providing smartphones, laptops and electric vehicles with significantly longer-lasting batteries.
This discovery complements the general trend of improving lithium-ion batteries. Recently, LeydenJar introduced an innovative battery with a silicon anode, which could also improve the efficiency of current battery technologies.
