Prototype battery types pictures and prices

The UNSW team's proton battery utilizes the TABQ material as the anode. This material exhibits superior proton storage capabilities and a lower redox potential range compared to previous organic materials. These properties contribute to the battery's high capacity and long cycle life.

“Proton batteries are gaining attention as an innovative and sustainable alternative in the energy field, and have been hailed as one of the potential solutions to next-generation energy storage devices,” concluded the press release.

These properties contribute to the battery's high capacity and long cycle life. In tests, the prototype proton battery demonstrated impressive performance. It achieved a long cycle life of 3500 cycles. It also exhibited high capacity and maintained its performance even in cold temperatures.

Lithium batteries also have very big challenges regarding fast-charging applications, safety, and they have low efficiency in cold temperature,” remarked Sicheng Wu, a PhD candidate from the School of Chemistry. Proton batteries offer a compelling alternative. They utilize protons, which are abundant and environmentally benign.

Plus, they can store up to three times more energy and experience less degradation over time than lithium-ion batteries. In 2024, Harvard researchers revealed a design that enables ultra-fast charging and thousands of cycles without degradation in solid-state batteries.

Where the original used a nickel-cobalt-manganese, the new and improved version uses lithium-iron-phosphate instead. The battery works on the same principle, using a thin nickel foil to rapidly hit extreme temperatures and charge up before cooling again, but these new materials offer a couple of advantages.
