Japanese engineers from NEC Corporation have developed a flexible, soft battery that is only about 0.33mm thick and can be charged in just 30 seconds.
NEC claims that this battery was developed for applications such as RFID (Radio Frequency Identification) cards and can provide enough energy for these cards to operate for several weeks without needing to be recharged.
This type of battery is derived from “organic batteries,” a technology developed by NEC that allows the use of environmentally friendly materials as compared to the chemical substances found in typical batteries. According to NEC, the company began its research in this field in 2000.
These thin batteries are crucial for RFID cards. Most of these cards are “passive” devices. They do not have the capability to send data on their own; they only function within a specific radio frequency range and at distances of just a few centimeters. The improved cards will resemble radio transmitters more closely, allowing them to send data over greater distances, so they can be read without needing to be close to a reader.
Earlier this year, NEC also introduced a larger version, considered as an emergency power reserve for personal computers. This battery would help maintain a PC for about 15 seconds after the main power is cut off, providing enough time to back up data and shut down the machine safely.
