The battery industry is constantly evolving, looking for solutions safer, more durable and sustainable. The Japanese company ELECOM presented the First PowerBank in the Based world On Sodium-ion technology, a real revolution in the portable batteries sector. This new device stands out for its reduced environmental imprint, a higher level of safety and a clearly longer life of life than traditional lithium -ion batteries.
Currently, the Lithium ion batteries they are the most common and feed devices such as Smartphone, tablet and laptop. According to the forecasts of Global Market Insightstheir market will grow with an annual compound rate (Cagr) of 15.8% between 2025 and 2034. However, these batteries have several disadvantages: they are heat sensitivewith a high risk of overheatingand their production has a strong environmental impact. The extraction of materials such as lithium and cobalt In fact, it generates high emissions of Co₂ and contributes to the exhaustion of natural resources.
To counter these problems, Elecom has developed the Powerbank de-C55L-9000based on technology Sodium-ion. Unlike lithium accumulators, this model uses sodium for cathode and sodium salts as electrolytematerials more abundant, easier to find and less polluting. In addition, the production process results less harmful to the environmentcontributing to greater sustainability in the portable batteries sector.
A powerbank resistant even at extreme temperatures
In addition to being more ecological, the De-C55L-9000 boasts exceptional resistance to adverse climatic conditions. It can work in a temperature range between -35 ° C and 50 ° Cbeing ideal for those who are in extreme environments such as deserts, mountains or regions characterized by strong thermal excursions.
From the point of view of the safetyElecom has equipped the device with an advanced thermal protection systemcapable of constantly monitoring the temperature to prevent the risk of overheating and thermal instability. With a capacity of 9,000 mAhPowerbank can recharge a phone with a 80 mh battery 2.9 times and a 3,000 mAh model 1.7 times.
One of the main strengths of this PowerBank is his high longevity. If a traditional lithium ion battery guarantees between 500 and 1,000 charging cycles, the de-C55L-9000 reaches up to 5,000 cycles before suffering a significant drop in performance.
The only disadvantage is represented by slightly higher weight Compared to lithium models: with its own 350 gramsis heavier due to the less energy density of Sodium-ion technology. However, its price remains competitivewith a cost of 9,980 ¥ (about 61 €)an interesting investment for those looking for a safer and more ecological alternative.
