Lithium-ion batteries are common in today's consumer electronics and mobile gadgets. Without them, no cost, no laptops or smart phones or digital cameras and camcorders. Even electric vehicles as a power source using a huge amount of lithium-ion batteries. However, no battery is immune from sudden failure or phase failure, due to permanent loss of capacity during storage. Scientists in Singapore have developed a tiny chip, which in real time monitors the "health" of the battery and reports the analysis results to the user.
Today batteries already supplied with a chip that monitors the voltage, temperature and current level of remaining charge. If the battery is overheated - the system warns the user about it, is a shining example of iPhone, which is displayed on the screen corresponding to the alert, if you permanently leave your gadget in direct sunlight. However, the current model battery monitoring chip is not able to anticipate potentially dangerous damage of the battery, that is exactly what Professor Rashid Yazami spodviglo from the Institute of Energy Research at Nanyang Technological University in Singapore to develop its own version of the microprocessor.
"Faulty lithium-ion batteries are a serious danger for electric vehicles and even some models of modern aircraft, which contain huge sets of such batteries. Just one a failed battery can cause a chemical reaction, followed by a fire nearby batteries, which may cause an explosion. I dream that in the future each battery will be equipped with such a chip, that will minimize the risk to the lives of people, "- explains the professor.
Professor Yazami at the time invented a graphite anode, which is still used in lithium-ion batteries, so listen to his opinion many experts. He developed an updated model of the chip accurately monitors any changes in the condition of the battery, in addition, of course, has the above-mentioned parameters, which are able to monitor and old processors. The professor has developed its own unique algorithm based on the equations of electrochemical thermodynamics, which will warn the owner or an electric gadget that soon one or more of the batteries may be damaged.
Updated processor quite small and portable so that it can be integrated into virtually any battery ranging from mobile devices to large-sized sets of batteries in electric vehicles, and aircraft. The development of the chip has been going on for more than five years, and now she has moved into a phase of commercial release of the final product.
