When will battery technology have a revolutionary breakthrough?

Consumer electronics, automobiles, and grid storage are currently the three industries where batteries are important applications. I call these three industries the three areas where people connect with batteries. Each field has different requirements for batteries, so the batteries used may (sometimes) be very different. The cell phone in your pocket needs a sturdy, safe battery, and weight and cost don’t need to be considered too much. As for the automotive battery industry, there are many batteries required, so cost, weight, and cycle life (if a new Tesla needs to replace a new battery every two years, you will be crazy) become very important. Batteries used to store electricity for houses and power grids do not require high weight or size. Said Winkter Srinivasen, deputy director of research and development at the United States Joint Center for Energy Storage Research. Almost every part of the electronics industry requires batteries, which are also limited by the power output and energy life of the batteries. 'Power Magazine' editor-in-chief Stefano Passerini pointed out that the development or progress of batteries is much slower than in other areas. This is the limitation of the battery itself. You cannot expect to have a battery that can power a mobile phone for a week or a month. Because the maximum energy stored in the battery is determined by the inherent elements. In 1991, Sony introduced the first commercial lithium-ion battery, which is still used as the mainstream electronic device battery technology. Because lithium is the lightest alkali metal element, it has the characteristics of being smaller, lighter, and higher energy density, so it quickly replaced nickel batteries. Among the constituent materials of lithium-ion batteries, there are iron phosphate, manganese, graphite, titanate and other metal and non-metal materials. However, it is necessary to rely on the insertion and extraction of lithium in the positive and negative electrodes to achieve electrical energy and The mutual conversion of chemical energy finally completes the charge and discharge process. However, the technological progress of lithium-ion batteries has been slow. At present, the energy density, high and low temperature characteristics, and rate performance of lithium-ion batteries are far higher than those of lead-acid and nickel-hydrogen batteries, but it is still difficult to meet the rapidly rising demand for electronic products and electric vehicles. In recent years, researchers have worked hard to improve the energy density (volume-to-volume ratio), value, safety, environmental impact, and trial life of lithium-ion batteries, and are designing new types of batteries. But Passerini said that the traditional lithium-ion battery technology is now close to the bottleneck, and there is limited room for further optimization.
