Okay.
1. Good safety: Ruanfu lithium batteries are packaged in aluminum plastic film and have good safety performance. When a safety risk occurs, the battery can release energy by swelling or cracking to reduce safety risks.
2. High energy density: Ruanfu lithium battery has high energy density. Compared to other types of batteries, it is smaller, lighter and easier to carry. This makes Rufu lithium batteries widely used in fields such as portable devices and electric vehicles.
Although soft lithium batteries are not popular in China, their international market share reaches 70%. The following are the advantages and disadvantages of soft lithium batteries:
1. Advantages
1. Good safety performance: batteriesithium soft-packed are structurally packaged in lithium-wrapped aluminum-plastic film. batteries usually swell first or crack due to the seal to release energy, and there is no risk of explosion like lithium batteries packed in rigid packaging.
2. Light weight: The weight of the soft pack battery is 40% lighter than the same capacity lithium battery with steel case and 20% lighter than the battery with aluminum housing
3. Small internal resistance: domestic; soft pack The minimum internal resistance of the battery core can be less than 35m?, which greatly reduces the battery's self-consumption
4. Flexible design: size and The shape of soft battery can be designed according to actual needs, unlike hard batteries which only have round and square options.
2. Inconvenients
1. Imperfect supply chain: purchasing some raw materials and production equipment for lithium soft-pack batteries The channel is still relatively single. problems will arise with suppliers, this will have a certain impact on the production and operation of battery companies and the stability of supply of automobile manufacturers;
2. High cost: At present, the high-end aluminum-plastic film used in domestic soft lithium batteries still depends on imports, and the cost is very high ;
3. Few models: existing soft-pack lithium batteries The models are very limited and the cost of developing new models is too high. At this point, soft-pack lithium batteries can only meet a small portion of market demand.
Are flexible lithium batteries suitable forblow them up?
As the above shows, soft lithium batteries will not explode. In extreme cases, this type of battery can crack from the seam to release energy. will not explode like a packed lithium battery to a certain extent. Lithium-ion batteries are at risk of exploding once the energy has accumulated.
In foreign markets, the number of models equipped with soft-pack batteries is still very large. According to incomplete statistics, more than 30 models are equipped with it. Soft-pack batteries have been installed. Among the 20 best-selling new energy passenger cars in Europe in 2020, 15 models are equipped with soft-pack lithium batteries, so there is no need to worry too much about battery safety.
