In a significant advancement in battery technology, Japanese company Elecom has launched the world’s first powerbank powered by sodium-ion batteries. This innovative device, named the Elecom DE-C55L-9000BK, boasts a capacity of 9,000 mAh and is designed to last for nearly 13 years, with the ability to handle up to 5,000 charge cycles about ten times more than traditional lithium-ion batteries.
Sodium, which is abundant and does not require water or mining for extraction, offers a more environmentally friendly alternative to lithium-ion batteries. Sodium-ion batteries are also capable of functioning in extreme temperatures, ranging from -35 to 50°C, making them more versatile for various conditions.
The Elecom powerbank features two output ports: one Type-C port that can deliver 45W and one USB-A port with an 18W output. Together, they can provide a total output of 20W. The powerbank is equipped with LED indicators to show the current charge level. According to Elecom's tests, it can charge an iPhone 16 1.4 times, a 10th Gen iPad 0.6 times, and a 2022 MacBook Air 0.3 times.
Charging the powerbank is efficient as well, the Type-C port can charge it at 30W, allowing it to fully recharge in just 2 hours. Weighing in at 350 grams, it is heavier than many similar powerbanks, which typically weigh around 200 grams.
The Elecom powerbank is priced at approximately $67 (or 9,980 yen) and is available for pre order at Elecom Store, with shipping expected to start at the end of this month. While the price may seem high, it reflects the current production levels of sodium-ion technology. Fortunately, these batteries can be manufactured using existing lithium-ion production infrastructure, which could help reduce costs in the future.
However, sodium-ion batteries do have some limitations. They are less dense, hold less charge, and are heavier than their lithium-ion counterparts. Additionally, they have a maximum amperage limit of 5 Amps unless upgraded. As a result, sodium-ion batteries may not completely replace lithium-ion or silicon-carbon batteries anytime soon, but they could find a place in budget smartphones, gadgets, and home appliances that require lower power.
