New smartphone battery tech boosts durability and recyclability
Australian scientists have introduced an innovative type of battery designed for smartphones. They claim the new battery will be more durable and suitable for reuse, potentially extending its lifespan up to three times.
If Australian researchers' predictions are realized, smartphone replacements could become less frequent in the future. Many users are familiar with the problem where the phone's battery loses its efficiency after about two or three years, and the device quickly discharges. The new batteries these scientists are working on are expected to not only last longer but also be more recycling-friendly.
Are we on the brink of a smartphone battery revolution?
In their research, specialists highlight that only 10% of used phones in Australia are recycled. A similar situation exists in other parts of the world because processing devices with lithium-ion batteries is complex and not cost-effective. To change this, scientists from RMIT in Melbourne have used MXene—a compound comparable to graphene with high electrical conductivity—instead of lithium.
Although MXene rusts over time, engineers from RMIT have found a way to solve this problem. Tests have shown that exposing the battery to sound waves at a frequency of 10 hertz for a minute effectively removes rust, allowing the battery to be reused.
How long will the new battery last?
This process can be repeated twice, meaning that with smartphones' standard battery life of about three years, new MXene batteries could last up to nine years.
Of course, this assumes that other smartphone components operate flawlessly. Even if the new batteries do not result in less frequent phone changes, introducing such a solution is a step towards more efficient battery recycling. Ultimately, this could help reduce the amount of electronic waste. Researchers are already seeking business partners interested in bringing this technology to the market.
