Mya Le Thai develops ultra-durable battery technology

Scientist Mya Le Thai, a Vietnamese-American researcher, has developed a method to significantly increase the lifespan of rechargeable batteries. While conducting research as a doctoral student at the University of California, Irvine (UCI), Le Thai discovered that coating gold nanowires with manganese dioxide and an electrolyte gel could prevent the structural degradation typically seen in battery materials.

During testing, the device demonstrated remarkable durability, completing 200,000 charge-discharge cycles within three months without significant capacity loss. For comparison, standard laptop batteries typically last between 300 and 500 cycles, and conventional nanowire structures often fail after 5,000 to 7,000 cycles.

Researchers suggest this technology could theoretically extend the functional life of devices like laptops, smartphones, and electric vehicles to a scale equivalent to 400 years of use. This breakthrough offers the potential to create much longer-lasting electronics and reduce the environmental impact of lithium-ion battery waste.
