With the rapid development of the smart home industry, lithium-ion batteries have become the core power support for various household appliances. With the advantages of light weight, long battery life, low power consumption and high safety, they have gradually replaced traditional nickel-cadmium and nickel-metal hydride batteries, and are widely used in portable and wireless household appliances. They have profoundly changed people's lifestyles, provided important support for the miniaturization and convenience upgrade of home appliance products, and their performance directly affects the user experience and service life of home appliances.

　　The core advantage of lithium-ion batteries for household appliances is their adaptability to the diversified use scenarios of home appliances, taking into account practicality and safety. Compared with traditional batteries, they have higher energy density, can provide more durable power in the same volume, and are suitable for small household appliances with high-frequency use such as wireless vacuum cleaners, portable juicers, and electric toothbrushes. A single charge can meet the needs of multiple uses, eliminating the need for frequent charging and improving the convenience of use; at the same time, their self-discharge rate is low, and the power loss is slow when idle, which can maintain stable power even when not in use for a long time, suitable for home appliances used intermittently such as humidifiers and smart speakers.

　　Safety is the core consideration of lithium-ion batteries for household appliances. Such batteries are all equipped with an intelligent protection system, which has overcharge, over-discharge, short-circuit and over-temperature protection functions, which can effectively avoid problems such as battery bulging and leakage, adapt to the long-term use needs of home appliances, and ensure the safety of home use. In addition, it is more environmentally friendly, free of heavy metal pollution, and recyclable, which conforms to the development trend of green home appliances. It is widely used in various household equipment, from small portable home appliances to large energy storage home appliances, covering all aspects of life. Today, with the iteration of battery technology, lithium-ion batteries for household appliances have continuously upgraded in terms of battery life, service life and safety, which not only meet the low power consumption needs of home appliances, but also achieve energy saving and consumption reduction, promoting household power equipment to develop in a more intelligent, green and convenient direction, and becoming an indispensable part of modern family life.
