Researchers at Linköping University, Sweden, have developed a sustainable and cost-effective battery using zinc and lignin that can be recharged over 8,000 times.
This battery aims to provide affordable energy storage solutions for low-income countries where electricity access is limited, additionally, it offers similar energy density to lead-acid batteries but without toxic lead. It maintains about 80% performance over its lifespan and retains charge for a week. Zinc and lignin are cheap and abundant, making the battery recyclable and cost-effective.
The researchers aim to scale production for larger applications, emphasizing the importance of starting with green technology in infrastructure development to avoid climate catastrophe.
