A battery refers to a portion of the space in a cup, tank, or other container or composite container that contains an electrolyte solution and metal electrodes to generate electricity, and a device that can convert chemical energy into electrical energy. It can be divided into positive and negative electrodes. With the advancement of technology, batteries generally refer to small devices that can generate electricity. Like solar cells. The performance parameters of batteries mainly include electromotive force, capacity, specific energy, and resistance. By using batteries as an energy source, a current with stable voltage, stable current, long-term stable power supply, and minimal external influence can be obtained. The battery structure is simple, convenient to carry, easy to charge and discharge, and is not affected by external climate and temperature. Its performance is stable and reliable, and it plays a significant role in various aspects of modern social life. The IEC standard, also known as the International Electrical Commission, is a worldwide standardization organization composed of various countries' electrical committees. Its purpose is to promote standardization in the field of electrical and electronic technology worldwide. The standard for nickel cadmium batteries is IEC285, the standard for nickel hydrogen batteries is IEC61436, and the standard for lithium-ion batteries is IEC. Generally, the battery industry is based on SANYO or Panasonic standards. The commonly used IEC standard for batteries is IEC602851999 for nickel cadmium batteries; The standard for nickel hydrogen batteries is IEC614361998.1; The standard for lithium batteries is IEC619602000.11. The commonly used national standard for batteries is GB/T11013 for nickel cadmium batteries_ 1996GB/T18289_ 2000; The standard for nickel hydrogen batteries is GB/T15100_ 1994 GB/T18288_ 2000; The standard for lithium batteries is GB/T10077_ 1998YD/T998_ 1999, GB/T18287_ 2000. In addition, the commonly used standards for batteries include the Japanese industrial standard JIS C for batteries and the enterprise standard for batteries developed by SANYOPANASONIC company
