Battery life of electronic devices has always been a major problem affecting the experience, from smartphones to popular wearable devices. Obviously, you won't buy a smartwatch that recharges every day, so researchers are actively developing new types of batteries to fundamentally solve the problem. A new wide-temperature button battery using lithium fluoride (br) is expected to provide wearable devices with a battery life of more than 10 years without charging, according to the latest research results. According to reports, laboratory researchers have developed a new type of battery based on lithium fluoride (br) chemical formula, which can provide electricity for wearable devices and health care equipment for 10 years. Lithium fluorocarbon wide-temperature button batteries can be as small as coins and can power low-power fitness trackers or wearable devices that assemble sensors for years. Wearable devices mainly send users a small amount of information, do not need much electricity, can extend the life of cfx batteries. "but the battery can't be rechargeable. It's a disposable battery." But to be sure, the br battery is nothing new. The company is already selling special batteries based on lithium fluoride wide-temperature button batteries for motherboards, backup power supplies, night vision goggles and other electronic devices, which can come in different sizes. The br chemical formula is known to be one of the highest theoretical energy capacity chemical reactions relative to other popular chemical reactions for lithium batteries. "the battery is based on the old theory, but the design is new. This is a big breakthrough. " In the experiment, the researchers developed and tested a real br battery, using solid electrolytes to increase the energy capacity of the battery. The existing lithium batteries use positive cathode and negative positive electrode, and lithium ion can move between them when charging. During charging, lithium ions are moved from the cathode to the anode for storage. During discharge, lithium ion moves from anode to cathode and supplies power to the equipment. The new br battery design has solid lithium thiophosphate multipurpose electrolytes which can be used as ion conductors and cathodes. Electrolytes can carry storage charges and help to increase the energy capacity of batteries. Br battery prototype products use solid electrolytes, while ordinary batteries use liquid electrolytes.
