Organic batteries have long been considered the holy grail of sustainable energy storage because they are lightweight, recyclable, and free from toxic metals, but they have always fallen short in power and stability.
Now, a research team from China and Singapore has built an organic polymer battery that rewrites those limits, achieving record voltage and longevity without sacrificing sustainability.
The result is a battery that not only lasts but performs like never before.
The study, led by scientists from Nanjing University of Posts and Telecommunications, the National University of Singapore, the Suzhou Institute of Nano-Tech and Nano-Bionics, and A*STAR, unveiled a hexaazatriphenylene-based polymer—called HAT-TP—that sets a new benchmark in energy storage.
It delivers an impressive initial discharge voltage of 1.32 volts and retains 93.4% of its capacity after 40,000 cycles.
This achievement marks one of the most durable performances ever recorded for aqueous zinc–organic batteries, a field that has struggled with poor cycling stability and capacity fading.
