Lithium ion batteries have been widely used in consumer electronics products since their birth. In recent years, it has made great progress in the field of electric vehicles, making carbon-free travel possible. What is the difference between them? Generally speaking, in consumer electronic devices such as mobile phones and smart watches, lithium ion batteries with high energy density are used, such as lithium lithium cobalt oxide. Although such batteries may bring some safety hazards, but because of their small size and inseparability from the shape of the human body, the use environment is generally not so harsh, so the risk is generally controllable.

In the case of all new batteries, the battery capacity test discharge table. The capacity of the ordinary power lithium battery is about 1000-1500mah, while the capacity of the ordinary lithium battery is above 2000mAh, and some can reach 3400mah. In contrast, the energy density of power lithium batteries on electric vehicles is generally not as high as that of consumer electronics products to reduce safety risks. After all, the power battery pack of an electric car is composed of hundreds of batteries. If the risk probability of a certain battery increases, the risk probability of the entire battery pack will greatly increase.

This is why electric car companies will design more complex active/passive cooling systems for power battery packs than digital electronic products, as well as accurate battery control systems. In addition, the life of high-energy density lithium-ion batteries is usually short, and the life cycle of consumer electronics products is mostly around 2 years, far lower than that of electric vehicles. Therefore, high energy density batteries can better meet the needs of consumer electronics products, but are not suitable for electric vehicles.

Power lithium battery refers to a battery that provides power for transportation vehicles, and is generally compared with a small battery that provides energy for portable electronic devices; while a common lithium battery is a primary battery that uses lithium metal or lithium alloy as a negative electrode material and a non-aqueous electrolyte solution Batteries are different from rechargeable lithium ion batteries and lithium ion polymer batteries.

In an interview with the media, Xie Yezhuang predicted that by 2025, electric vehicles will account for 15% of new car sales, but the key to restricting the development of electric vehicles may be whether the power battery can be recycled. If human beings can obtain the raw materials of power batteries from the recovered power batteries, then this problem will be solved, and the electric vehicle industry will also have a longer-term development.
