Australian breakthrough: New smartphone battery could triple lifespan
Australian scientists have introduced an innovative type of battery designed for smartphones. They claim that the new battery will be more durable and suitable for reuse, potentially extending its lifespan up to three times.
If the predictions of Australian researchers are realized, smartphone replacements could become less frequent in the future. Many users are familiar with the issue where the phone's battery loses its efficiency after about two or three years, causing the device to discharge quickly. The new batteries being developed are not only expected to last longer but also to 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 complicated and not cost-effective. To address this, scientists from RMIT in Melbourne 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 Hz 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 the standard battery life in smartphones being 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 allow for less frequent phone changes, the introduction of 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 implementing this technology in the market.
