Funeng Technology released a new battery: 400 kilometers of energy in 10 minutes

Funeng Technology officially launched a new power battery solution – SPS (Super Pouch Solution), which integrates four innovative technologies: large pouch cells, large pouch battery systems, large pouch battery manufacturing and direct recycling. , cost reduction and efficiency enhancement, and adaptation of models to create products that meet customer requirements and user needs.

Large soft pack battery

The full-pole and multi-pole large soft-pack power cells launched by Funeng Technology change the multi-cell series design of the previous generation, thereby simplifying the battery system structure; it has a charge and discharge rate from 2.4C to 5C or even higher, satisfying Power requirements of various new energy vehicles; semi-solid electrolytes are used to reduce the amount of liquid electrolytes and improve the intrinsic safety of batteries.

Thanks to the high compatibility with the material system, the large soft pack battery is suitable for high nickel ternary to low nickel lithium-rich manganese, lithium manganese iron phosphate, sodium ion, etc., matching different customer requirements.

Large soft pack battery system

SPS large pouch battery system adopts the integrated design of high-efficiency liquid cooling plate and chassis. % to 75%.

While the volume utilization rate has reached a new high, the high-efficiency liquid-cooling plate and heat-conducting sheet provide double-sided liquid cooling and high-efficiency heat exchange with three-sided heat transfer. The heat dissipation efficiency of the battery system is increased by 4 times, and the precise and comprehensive temperature control ensures the cycle life of the battery system. More than 3000 times.

On this basis, a variety of materials form 6-sided protection for the large soft-packed cells, coupled with the design of efficient exhaust channels and heat exchange capabilities, the SPS large soft-packed battery system is equipped with 8-series or higher nickel content cells. The thermal runaway non-diffusion (NO TP) of the single cell can still be achieved.

The all-pole tab and lamination process of the large soft-packed cells bring lower internal resistance and better low-temperature discharge performance. The liquid-cooling plate and nano-insulation materials balance the internal temperature of the battery system. The new low-temperature rapid self-heating design meets the requirements of SPS poles Normal charging in cold conditions. The experimental data shows that in the -20 ℃ environment, the capacity of the SPS system remains more than 90%, and the charging time is shortened by half.
Compared with models equipped with 4680 cylindrical batteries, the volume utilization rate of Funeng Technology SPS is 12% higher, it has 3 times the cycle life, and the thermal conductivity is increased by 60%.
In view of the power of 300-350kW of fast charging piles in the future, SPS uses large soft-packed cells with different charging rates to achieve a unified configuration of “charging for 10 minutes and lasting 400 kilometers” to meet the travel and energy replenishment needs of various users.
Funeng Technology SPS can flexibly adjust the chassis height from 85mm to 145mm by adjusting the thickness of the battery cells. It is equipped with large soft-packed cells with different energy densities. The battery system capacity covers 80kWh to 150kWh, meeting the electrification needs of various passenger vehicles. The same chassis and one battery can meet the needs of all passenger cars, shorten the research and development cycle for vehicle enterprise customers, reduce procurement costs, and ensure stable supply.
Large pouch battery manufacturing and direct recycling
On the manufacturing side, the commissioning of large soft-coated cells will greatly reduce production capacity investment costs and manufacturing process costs. Equipment investment will be reduced by 50%, plant area will be reduced by 60%, and manufacturing energy consumption and costs will be reduced by 35% and 30% respectively.
It is worth mentioning that Funeng Technology has developed and verified the direct recycling technology of lithium batteries for more than 10 years, which can retain the crystal structure of cathode materials and reuse them, further reducing costs and energy consumption, and increasing the material utilization rate to 99%. above. According to data from a third-party laboratory in the United States, there is no significant difference in performance between cells made of 25% directly recycled cathode materials and cells made of new cathode materials.
