　　The penetration rate of soft-pack lithium battery technology in power batteries is accelerating

　　The penetration rate of soft-pack lithium battery technology in power batteries is accelerating. my country's new energy vehicle market is growing rapidly, and power batteries are the source of power for new energy vehicles. With the performance advantages of high safety performance, high energy density, and long service life, the application proportion of soft-pack lithium batteries in the new energy vehicle market is increasing year by year. Soft-pack lithium batteries have many advantages such as high safety performance, light weight, high energy density, low internal resistance, good cycle performance, long service life, and flexible design.

　　The penetration rate of soft-pack lithium battery technology in power batteries is accelerating

　　With the adjustment of subsidy policies, the maturation of soft-pack lithium battery pack technology and the substantial increase in production line automation, many power battery field, material field, and equipment manufacturers have "changed their formation" to enter the soft-pack market. Soft-pack batteries will occupy a higher proportion of the incremental market. Driven by the core goals of high energy density and high endurance, the penetration rate of soft-pack lithium batteries in the new energy vehicle market is gradually accelerating, and it has also become an important variable triggering changes in the domestic power battery market structure.

　　As an important means of lightweighting and high-energy batteries, soft-pack lithium battery pack technology is expected to continue to increase penetration in newly expanded production capacity, thereby achieving a growth rate higher than the industry's production expansion scale. The process differences between soft-pack batteries and prismatic batteries have led to an upgrade in the demand for high-end lamination equipment and equipment such as liquid injection and packaging in the middle and rear stages. Due to the vast space in the new market, lithium battery equipment companies with certain soft packaging technology foundation are expected to accelerate their layout.

　　Reasons for the accelerated application of soft-pack lithium battery market:

　　First, under the adjustment of subsidy policies, the advantages of high energy density and long cruising range of soft-pack batteries are more in line with market requirements.

　　Second, soft-pack battery technology is becoming increasingly mature, and the application market is further extending from commercial vehicles to passenger vehicles.

　　Third, the degree of automation of the soft-pack lithium battery pack production line has been greatly improved, and the cost of soft-pack batteries has been reduced due to increased production capacity utilization.

　　The editor learned that in terms of market application, the passenger car field covers BAIC New Energy, BAIC Motor, Chery, Zotye, SAIC-GM-Wuling, Great Wall, Zhidou, Jiangling, Chongqing Changan, Jiangxi Changhe, Shaanxi Automobile Tongjia and other car companies. Actively introducing soft-pack lithium battery packs. In particular, the introduction of BAIC New Energy's EC series and Chery's eQ best-selling models has driven a substantial increase in soft-pack battery production capacity.

　　Taken together, with the advantages of safety, high energy density, and flexible design, soft-pack lithium battery packs will occupy a higher proportion of the incremental market. The vast market space of soft-pack batteries has also become a unanimous target for power battery fields, materials fields, and equipment manufacturers.

　　At the technical level, batteries have significantly improved in terms of energy density and group efficiency; at the market level, in addition to battery companies focusing on soft pack technology routes that are actively expanding production, power battery companies that were mainly square at that time also began to accelerate the soft pack lithium Battery pack layout.

　　Benefiting from the growing market demand for lithium battery packs and the accelerated penetration of soft-pack lithium batteries in the power field, my country's soft-pack lithium batteries will maintain a growth rate of 35%. By 2020, its market demand will reach 58.9GWh, with a penetration rate of 58.9GWh. will reach 41%. The market demand for soft-pack lithium batteries in my country is growing rapidly.

　　At this stage, the penetration rate of my country's soft-pack lithium battery packs in the power battery field is still low, only about 12%. As new energy vehicle companies gradually increase their recognition of soft-pack lithium batteries, the penetration rate of soft-pack lithium batteries in the power battery field is expected to increase rapidly. In 2017, my country's soft-pack power batteries have begun to increase in volume, with output value increasing by more than 30% year-on-year. In the future, with the continuous expansion of the new energy vehicle market, the power battery field will become the main driving force for the development of the soft-pack lithium battery industry.

　　Advantages of soft pack lithium batteries

　　●Good safety performance: Soft-pack batteries have less electrolyte leakage, and soft-pack batteries will inflate and crack in the event of safety hazards, unlike hard-shell batteries that will explode if the internal pressure is too high;

　　●Light weight: Soft-packed lithium battery packs are 40% lighter than steel-cased prismatic batteries of the same capacity and 20% lighter than aluminum-cased prismatic batteries;

　　●Large battery capacity: The soft pack saves 20% of the volume, 50% higher than the steel shell battery of the same size, and 20~30% higher than the aluminum shell battery;

　　●Good cycle performance: Soft-pack batteries have a longer cycle life, and 100 cycles of attenuation are 4% to 7% less than aluminum cases;

　　●Small internal resistance: The internal resistance of soft-pack batteries is smaller than that of lithium batteries, and the domestic minimum can be less than 35mΩ, which greatly reduces the battery’s self-consumption;

　　●Flexible design: The shape can be customized according to customer needs, and can be made thinner. Ordinary aluminum shells can only be 4mm, and soft bags can be 0.5mm.

　　The expansion of soft-pack lithium battery production capacity will inevitably lead to changes in related equipment companies. With the improvement of the production technology of soft-pack lithium battery packs and the increasing market requirements for vehicle endurance, soft-pack batteries have obvious advantages in the new energy vehicle market and have begun to gradually increase their share in high-end models. The demand for aluminum-plastic films The volume is increasing rapidly with the expansion of soft pack battery production.
