A research team at The Hong Kong University of Science and Technology (HKUST) has developed a new electrode design that is set to enable the rechargeability of alkaline zinc batteries, one of the most common types of non-rechargeable batteries used in our daily lives, shedding light on a wider application of rechargeable batteries.
Batteries are ever important in the age of smart cities and global digitalization. Yet, a majority of batteries in the market are not rechargeable, or called primary batteries. They are disposed after a single use, an unsustainable practice that poses a serious threat to the environment.
Compared with other types of primary batteries, alkaline zinc batteries are cheap, safe, and energy-dense. They are used in many household items such as flashlights and remote controllers. Given the advantages, there is never a lack of effort from researchers worldwide…
