Ways to improve the safety of lithium batteries

Lithium batteries have the characteristics of small size, large capacity, and long service life. Lithium batteries come in many forms and are widely used in consumer products such as mobile phones, notebook computers, cameras and clocks, medical equipment such as pacemakers, and even military and aerospace equipment. Researchers at the University of Cambridge said in October last year that they have developed a new battery lithium-oxygen battery or air battery that can still reach 90% efficiency after 2,000 recharges. The researchers said that it may take 10 years for this battery to be put into commercial use. Last week, Forbes stated that the U.S. Army Research Laboratory University of Maryland and U.S. researchers said that they have developed a salt water (water-in-salt) lithium battery, which has the potential for time and efficiency of lithium batteries, but at the same time does not Use of toxic chemicals and environmental pollution, such as sulfuric acid, lead, and cadmium. Batteries with relatively low processing hazards will have long-term effects on the environment and consumers. In April 2015, Tesla announced that it would establish a new business unit, Tesla Energy, to provide consumers and companies with home battery solutions. This has triggered intense discussions about the rapidly rising energy storage market. According to Forbes, given that Tesla has ordered more than 100,000 household battery solutions, this non-toxic, water-based lithium battery may be a good product. These new batteries are particularly suitable for applications that require kilowatts or megawatts of energy, such as electric vehicles, and can also be used for battery safety and toxicity priority applications, such as aircraft, naval vessels, spacecraft, and non-flammable batteries. The researchers said that the use of a water-based electrolyte containing a high concentration of lithium salt is a breakthrough. It changes the chemistry of the battery and forms a thin protective layer on the anode. The protective film is very important to the stability of the battery and to achieve the same performance as the existing lithium battery. Edward Schafer, director of the Energy and Power Division of the US Army Research Laboratory, said the discovery may improve battery safety. He said that the applications of the new battery include equipment carried and worn by soldiers, as well as the supply of safer and smaller energy storage equipment for equipment with limited space such as submarines.
