For electric vehicles and hybrid vehicles, the core technology is the battery. Compared with other types of batteries, although the power lithium-ion battery has the disadvantages of high price and poor safety performance, it has the important advantages of large specific energy and long cycle life. Advantages, so it has a broader development prospects. The technological development of power lithium-ion batteries is also changing with each passing day, with improvements in capacity and structure. Experts said that no matter which technical route the battery manufacturer adopts, it should meet the requirements of high safety in use, wide range of environmental temperature differences, and charging and discharging functionality. Conditions such as strong, high rate discharge and good usability.
Battery capacity involves technology and cost. Lithium-ion batteries can be divided into small batteries and large batteries according to their size. Small batteries are usually used in 3C electronic products. Related technologies and industries have developed very maturely, and overall profits are decreasing. More than 85% of current lithium-ion battery products are small batteries.
Large batteries are also commonly known as power batteries, and there are also two types of small power batteries and large power batteries. The former is mainly used for electric tools and electric bicycles, and the latter is used in the fields of electric vehicles and energy storage. At present, three types of electric vehicles, namely pure electric (EV), plug-in hybrid electric (PHEV), and hybrid electric (HEV), are in a period of rapid development and have attracted much attention from the industry. As the core of the future automobile industry, the development of the power lithium-ion battery industry has received unprecedented attention and has been raised to a strategic height by major countries. According to calculations by industry authorities, in recent years, the power lithium-ion battery market will exceed the scale of the global mobile phone lithium-ion battery market. This change will trigger a new round of investment in related manufacturing equipment and plants, and at the same time, a new entry into power lithium Major manufacturers in the ion battery industry will intensify technical competition in related fields.
At present, whether to use a single large-capacity battery technology solution or a small-capacity battery parallel technology solution has always been a matter of debate in the industry, and which technical route to use depends on the result of the battery pack. It depends on whether the size, weight, Product quality, performance, price, ease of installation and other aspects are competitive.
