What are our options for next-generation batteries?

Almost all smart phones in the world now use lithium-ion batteries, but what is annoying is that most smart phone batteries can only barely last for a day in normal use. Nevertheless, lithium-ion batteries have been used in electric vehicles, and energy storage grids are also coming. It seems that lithium has a bright future. One of the most fascinating events recently is that Tesla Motors announced that their newly launched residences are Powerwall batteries. The order has continued until mid-2016. The market demand is very strong and will soon reach an annual battery capacity of 35 gigawatt hours. The processing expects US household electricity consumption to be 1.2 million watt-hours per day. Lithium-ion battery products were first introduced by Sony in the 1990s. At that time, many people believed that lithium-ion batteries were a major breakthrough in rechargeable batteries: with their higher working voltage and higher energy density, lithium-ion batteries beat It was the dominant nickel metal hydride battery (NiMH). In addition, the use of lithium-ion batteries has also promoted the development of portable electronic devices. If there is no lithium ion battery, the weight of the latest Galaxy smart phone may reach three times the weight of the current mobile phone, and the volume will be twice as much. However, recently, lithium-ion batteries have begun to be under pressure. In more modern portable devices and the battery life of electric vehicles, the performance of lithium-ion batteries is not really satisfactory. In addition, compared with gasoline-powered vehicles, lithium brings more serious safety issues, especially the danger of fire.
