Application scenarios of energy storage batteries

　　The application of energy storage batteries is very extensive, including:

　　Electric energy storage: used for peak shaving and valley filling in the power grid, frequency regulation, emergency backup, etc.

　　Household energy storage: a household energy storage system used for nighttime power supply and emergency power supply of solar photovoltaic systems.

　　Portable energy storage: a power source for portable electronic devices such as laptops, mobile phones, and outdoor equipment.

　　Communication energy storage: As a backup power source for communication base stations, it ensures the stability of the communication network.

　　With the advancement of technology and the reduction of costs, the application of energy storage batteries in various fields will continue to grow. Especially lithium-ion batteries, due to their high energy density and long lifespan, are expected to dominate the energy storage market in the future. Meanwhile, new energy storage technologies such as flow batteries and sodium ion batteries are also constantly developing and are expected to play a greater role in the future energy storage market.

　　What are the commonly used standards for batteries?

　　Common IEC standards for batteries: The standard for nickel hydrogen batteries is IEC61951-2:2003; The lithium-ion battery industry generally follows UL or national standards.

　　Common national standards for batteries: The standards for nickel hydrogen batteries are GB/T15100_1994 and GB/T18288_2000; the standards for lithium batteries are GB/T1007_1998, YD/T998_1999,GB/T18287_2000。

　　In addition, the commonly used standards for batteries also include the Japanese Industrial Standard JIS C for batteries.

　　IEC, also known as the International Electrical Commission, is a global standardization organization composed of national electrical commissions, with the aim of promoting standardization in the field of electrical and electronic engineering worldwide. IEC standards are standards developed by the International Electrotechnical Commission.

　　The main components of nickel hydrogen batteries are: positive electrode sheet (nickel oxide), negative electrode sheet (hydrogen storage alloy), electrolyte (mainly KOH), separator paper, sealing ring, positive electrode cap, battery case, etc.
