Japan has developed a flexible lithium ion rechargeable battery
 |
During the "FPD International 2013" event held at the Yokohama Convention and Exhibition Center from October 23 to 25, 2013, the Japan Semiconductor Energy Research Institute unveiled a groundbreaking development: a flexible lithium-ion rechargeable battery. This was the first time the technology had been publicly demonstrated after years of research. According to the institute's representative, the growing interest in wearable devices like smartwatches prompted them to showcase this innovation. Alongside the battery itself, they also presented a bracelet-style device equipped with the flexible power source.
The battery measures 50mm x 40mm and is just 1.6mm thick, with a capacity of 300mAh. The team emphasized its durability, stating that it can withstand over 10,000 bending cycles at a radius of 40mm without any loss of performance. To achieve this flexibility, the researchers improved both the electrolyte material and the laminating process. This advancement could pave the way for more versatile and user-friendly wearable electronics in the future. (Reported by Neejin, "Nikkei Electronics")
This breakthrough highlights the ongoing efforts in battery technology to keep up with the evolving demands of modern electronics. As wearables become more integrated into daily life, the need for compact, durable, and flexible power sources is becoming increasingly important. The Japan Semiconductor Energy Research Institute's work represents a significant step forward in this direction, offering a glimpse into the future of portable energy solutions.
