Traditional lithium-ion battery technology bottleneck -Lithium - Ion Battery Equipment
“Consumer electronics, automotive and grid storage are the three industries where batteries are currently used. I call these three industries the top three areas where people connect to batteries. Each area has different requirements for batteries, so the Batteries can also be (sometimes) very different. Your phone in your pocket needs a strong, safe battery, and weight and cost don't matter too much. And for the automotive battery industry, many batteries are needed, so the cost and weight and cycle Longevity (you'll be mad if a new Tesla needs a new battery every two years) becomes important. Batteries used to store power for the house and the grid don't require much weight or size." U.S. Winkert Srinivassen, deputy director of research and development at the Joint Center for Energy Storage Research, said.
Almost every part of the electronics industry requires batteries and is therefore limited by their power output and energy life. Stefano Passerini, editor-in-chief of Power Magazine, pointed out, "The development or progress of batteries is much slower than in other areas, which is the limitation of the battery itself, you can't expect to have a mobile phone that can power a phone for a week or a month. Batteries. Because, the maximum amount of energy stored in batteries is determined by the inherent elements.”(Lithium - Ion Battery Equipment)
In 1991, Sony launched the first commercial lithium battery, which is still used as the mainstream electronic equipment battery technology. Because lithium ions are the lightest alkali metal elements, they are smaller, lighter, and have higher energy density, so they quickly replaced nickel batteries.
Among the constituent materials of lithium batteries, there are other metal and non-metal materials such as iron phosphate, manganese, graphite, titanate, etc., but only by the insertion and extraction of the element "lithium ion" in the positive and negative electrodes can it be realized. The mutual conversion of electrical energy and chemical energy, and finally complete the charging and discharging process.
However, technological progress in lithium batteries has been slow. At present, lithium-ion batteries are far higher than lead-acid and nickel-metal hydride batteries in terms of energy density, high and low temperature characteristics, and rate performance, but it is still difficult to meet the needs of rapidly growing electronic products and electric vehicles.
In recent years, researchers have worked hard to improve the energy density (charge-to-volume-capacity ratio), value, safety, environmental impact, and trial life of lithium batteries, and are designing entirely new types of batteries. But Passerini said that traditional lithium battery technology is now approaching a bottleneck, and there is limited room for further optimization.
