The days of using conventional power banks are over. A 13-year-long mobile phone battery is introduced in Japan
Many people all over the world now carry power banks or portable batteries, and the number of people using smartphones is rising. Despite continuous advancements, these gadgets, which keep everything at our fingertips, will eventually require portable batteries due to their growing capabilities. Since lithium-ion is the lightest and least dense metal in the periodic table, it provides the best weight-to-energy-storage ratio, which is why the majority of these batteries are lithium-ion.
However, sodium is currently gaining ground, and it is anticipated that sodium-ion batteries will surpass conventional batteries in terms of dependability.
With a lifespan of up to 5,000 full charge and discharge cycles, the first sodium-ion mobile phone power bank was unveiled by the Japanese company Elecom. When compared to the 500–1,000 cycles of lithium-ion batteries, this is an astounding figure. Even with heavy daily use, a 13-year lifespan is anticipated for the portable battery.
What additional benefits are available with these kinds of batteries? These batteries' sodium-ion technology enables them to function in temperatures between -34°C and 50°C without experiencing rapid deterioration, problems with capacity depletion, or slow charging rates at low temperatures. Furthermore, they can be completely discharged for long-term storage or transit, unlike lithium batteries, removing any possible hazards.
What drawbacks does it provide? It only has a 9,000 mAh capacity, despite being about the same size and weight as a 20,000 mAh power bank. This is a new technology that has the potential to advance further and surpass lithium-based batteries in price.
