To date, conventional batteries of solid-state electrodes and liquid electrolytes are proved to meet most of their applications. Conventional disposable systems have greatly satisfied the needs of portable electrical devices, such as zinc manganese batteries and alkaline manganese batteries. The system of lead acid and nickel-cadmium rechargeable batteries act as small energy storage units (for example, applications in rural areas, railways, and communication systems, etc.) and ground, air and sea journey for a long time. Over the years, the research and development of battery industries has been committed to existing systems, especially in terms of battery design and assembly.
However, this situation has changed in recent years. First, the development of semiconductor technology has enabled people to produce a large number of large integrated circuit products (ISI, VLSI, UISI), causing the revolution of the electronic industry. The price of microelectronics products is low, and it has been widely used in a similar equipment such as pocket calculator, electronic watch. In 1990, the output of the electronic watch in 1990 was 400 million. The development of large-scale integrated circuit electronic products requires support for small power supplies, which requires a higher energy and more superior discharge performance than traditional batteries.
Second, the end of the 1960s, the growing energy demand in industrial developed countries, the increasing rush of the world crude oil supply, prompting humans to develop new battery systems to meet the needs, which may be more important factors. This requires humans to more efficiently utilize the remaining mineral fuel resources and gradually turn to the development of cleaning renewable alternative energy sources. The use of discontinuous energy (such as solar energy, wind and tidal energy) and the key to the effective operation of conventional power plants are to provide a suitable energy reserve system. Although there are many energy reserves, such as pump power storage, compressed air storage, etc., but electrochemical storage battery is the preferred mode in most cases, and is easy to transport, flexible, and no sound, no pollution.
In this application, the battery must have the ability to use high-efficiency multiple depth discharge cycles and non-material degradation. Since a large amount of oil is consumed on a vehicle, this is a particularly inefficient utilization energy approach, which will cause environmental pollution in the urban area, so the possibility of replacing the internal combustion engine as the power of the vehicle is being attached importance. Many countries are currently developing advanced batteries in this purpose. The battery that is used as an electric vehicle power source is also part of the vehicle load, which requires high power quality and high cycle performance.
