aims at the market dividend of lithium-ion light-duty vehicles under the new national standard, and Tianneng’s lithium battery "changing array" layout.
On August 19th, Tianneng Lithium Battery's third 819 battery festival was held in Changxing, Zhejiang. Tianneng Lithium Battery has launched two major series of fist products for lithium battery light vehicle sharing, leasing, and battery swapping.
is different from the previous ternary material product lineup. The new products launched this time are: SLFP super lithium iron phosphate series battery products and LMFP lithium iron manganese phosphate series products.
Senior Engineer Lithium Battery was informed on site that both products are 48V20Ah in line with the new national standard capacity specifications. Among them, the specification of SLFP super lithium iron phosphate monomer is 3.2V-2000mAh, and the cycle life can reach 2000 times; the specification of LMFP lithium iron phosphate monomer is 3.6V-2100mAh, and the cycle life can reach 1000 times.
Tianneng Lithium Battery Dr. Fei Chen introduced that the two series of new products launched by Tianneng Lithium Battery have further optimization and innovation in terms of materials, battery cell structure design, PACK design, and manufacturing process. In terms of
materials, Tianneng’s two products use advanced super lithium iron phosphate materials and the latest lithium iron manganese phosphate material technology, composite carbon source coating, chain carboxylate electrolyte, and ceramic coating diaphragms. And high-performance artificial graphite anode. In terms of cell structure design, the company establishes a computer model to simulate the battery operation process, and conducts finite element thermal analysis on the electrodes to guide cell design. Based on the sample test data, the company further optimized the computer model, and through PDCA improvements, optimized the cell structure to the greatest extent to ensure the performance and safety of the cell. In addition, the company has also optimized key components such as caps and sealing rings. In terms of
PACK design, Tianneng adopts a brand-new waterproof and dustproof design, with a protection level of IP67. CQC certified fireproof materials are used to make the shell and bracket, thereby improving the flame retardant performance of the PACK. On the
software, through multiple protections, provide system security solutions. Such as: developed 13 strings of lithium battery protection board , voltage, current and temperature detection and protection functions, battery capacity calculation, electromagnetic lock, fire alarm and other functions. In terms of the manufacturing process of
, the company has an internationally advanced production line and adopts strict process control, especially dust, temperature and humidity have strict regulations.
Aiming at the application trend of lithium batteries in the new travel field of light vehicles, Li Mingjun, deputy general manager of Tianneng Co., Ltd. and president of Tianneng's lithium battery business unit, said that the main research and development directions of lithium battery technology for two-wheel electric vehicles in the future will focus on three points: safer , Smarter, longer life and environmentally friendly.
1. If lithium batteries want to be safe, there are at least three safety requirements: material safety, design safety, and process control safety. There must be reliable raw materials, standardized and unified standards, mature manufacturing processes, and more standardized charging and discharging environmental management technologies.
2. Lithium batteries need to be smarter, improve the in-depth development of BMS lithium battery management system technology, realize lithium battery overcharge protection, thermal management temperature protection, power management, GPS and Beidou positioning anti-theft protection, IoT remote monitoring and upgrade correction Management, human-computer interaction and other functions. So that the lithium battery becomes a smarter energy power device.
3. Lithium batteries need to be longer-lived and environmentally friendly. At present, Tianneng has been able to completely independently produce lithium batteries of two materials, ternary and lithium iron phosphate, through research and technology research on basic materials.
"Tianneng Lithium’s latest SLFP super lithium iron phosphate series battery products and LMFP lithium iron manganese phosphate series products have taken into account these demand points." Li Mingjun emphasized that Tianneng LMFP lithium iron phosphate series products have iron Lithium-level safety, ternary energy.
In the field of light-duty vehicle lead-acid batteries, Tianneng firmly occupies the leading position in the industry. After the new national standard is fully implemented, it will rely on new technologies, new products, heavy investment, and with the help of traditional offline channels, as well as in shared travel, exchange and lease With deep ploughing of the market, Tianneng's lithium battery products are expected to stand out.
At present, Tianneng has 5GWh battery cell production capacity. The battery core products cover cylindrical covering cylinders, soft packs, and squares; the material system covers two major systems: ternary and iron-lithium; and the market covers twoWheel vehicles, commercial vehicles, energy storage fields, 3C fields, special vehicles and AGV fields.
Li Mingjun said that the company will further expand its production capacity and increase production capacity by 3 times within three years to reach a production capacity of 100,000 units. While expanding and strengthening two-wheeled vehicles and low-speed four-wheeled vehicles, it will focus on the energy storage market, commercial vehicles, 3C fields, special vehicles and AGV fields, and overseas markets.
