Passed ISO900 1 certification, testing and approval by the Ministry of Industry and Information Technology, CE certification of the European Union and ROHS certification. In terms of large capacity, high voltage, long life, safety and environmental protection, the battery took the lead in realizing commercialization and large-scale production in China, and its level was first-class in the world, and it was absolutely leading in China, mainly reflected in the synthesis process and material composition of cathode materials for lithium-ion batteries, which overcame the technical bottlenecks of high-power charge and discharge and full-capacity repeated charge and discharge recognized at home and abroad, realized the large-scale production of cathode materials for lithium-ion batteries and filled the gaps at home and abroad. Based on five companies that can produce lithium-ion batteries in the world (A 123 in the United States, PHOSTECH in Canada, Bahai in China, Tian Lei and BYD), the technical indicators of Bahai lithium-ion batteries are in the leading position in the world. The comparison of relevant data is as follows: Battery composition: lithium phosphate battery C-LiFePO4 lithium cobaltate battery LiCoO2 lithium manganate battery LiMn2O4 lead-acid battery NiMH battery has the best safety and environmental protection requirements, and does not explode, catch fire or smoke under abuse test. Moreover, it is most in line with the requirements of environmental protection, without any toxicity, without using any scarce resources, and the stability of heavy metals is extremely poor, very unsafe and easy to explode.
Abuse of the test can easily lead to thermal runaway (while releasing oxygen as an accelerant), so the safety of fire and explosion is acceptable.
It seriously pollutes soil and water sources, destroys air and ecological balance, and also causes metabolic, reproductive and neurological diseases, induces malignant tumors in children, and even leads to death.
Waste lead-acid batteries are difficult to recover, with high utilization cost and poor stability, and there is a fire phenomenon in abuse test. The life (number of cycles) of heavy-duty lead-acid batteries is the best at room temperature, 1C charge-discharge cycles 1000, and the capacity retention rate is above 85% (theoretical cycle number is 2000), which is acceptable.
Excellent safety performance
Lithium ferrous phosphate completely solved the potential safety hazards of lithium cobaltate and lithium manganate. Lithium iron phosphate lithium ion battery is the only absolutely safe lithium ion battery in the world at present, and its stability can reach 400-500℃ at high temperature, which ensures the inherent high safety of the battery and will not explode or burn due to overcharge, overheating, short circuit and impact.
Long service life
The cycle times are high, and the room temperature charge-discharge cycle is 1000, and the capacity retention rate is over 85%, which is 8 times that of lead-acid battery, 3 times that of nickel-hydrogen battery, 4 times that of lithium cobaltate battery and 4-5 times that of lithium manganate battery.
Absolute environmental protection, zero pollution
The battery does not contain any heavy metals and rare metals (Ni-MH battery contains rare metals), and it is non-toxic (CE certification) and pollution-free, which meets the requirements of European ROHS. This is definitely a green battery. Lithium ferrous phosphate material is pollution-free in production and use.
Light weight, 1/3 of lead-acid battery.
Small size, 2/3 of that of lead-acid battery.
The single cell voltage is high, 3.2V, and there are few series connections, so the reliability of the battery pack is high.
It can be used for high current and high power charge and discharge.
Memoryless effect
Rechargeable batteries often work when fully charged, and their capacity will soon drop below the rated capacity. This phenomenon is called memory effect. For example, Ni-MH batteries and Ni-Cd batteries have memories, while lithium iron phosphate lithium ion batteries do not. No matter what state the battery is in, it can be used whenever it is charged, and there is no need to discharge before charging.
Excellent fast charging characteristics.
high-temperature resistance
It can be discharged in the temperature range of -20℃-+75℃, and the peak value of Ferrous lithium phosphate can reach 350℃-500℃, while that of lithium cobaltate and lithium manganate is only about 200℃. Market and marketing adopt the market strategy of subdividing the application market, breaking through at home after abroad.
In the field of pure electric vehicles and special vehicles:
Participate in domestic and international trade exhibitions and explore domestic and foreign customers. In the European and American markets, we have developed dozens of stable customers. In 2009, we added more than 65,438+000 potential customers.
In the field of pure electric vehicles:
Participate in domestic and international trade exhibitions and explore domestic and international markets. Established a strategic cooperative relationship with the top five pure electric vehicle customers in the world. Both the sample list and the small-scale suitable list have passed, and there will be large orders in the future. In China market, according to the characteristics of China market, high and medium prices induce the market to start.
Solar energy application field:
Iron power battery is used as solar storage battery. The solar energy market is very big, and so is its energy storage battery market. In terms of market share: 50% each. The solar energy industry will also develop greatly in recent years. It is powered by an iron-powered battery and will have a great market space.
In the fields of electric power, telecommunications, power tools and national defense construction, it has a broad market:
UPS uninterruptible power supply and iron power battery have very broad application fields. With the increase of social demand, various governments have introduced support policies. We seize the opportunity and develop rapidly.
New industries, new energy and new development
We are constantly developing the application scope of iron power batteries. In the competition of new energy industry, it is rapidly produced and expanded.
Group marketing, the battery part adopts direct selling method, and the products are sold directly to the end users (convenient after-sales service). Electric vehicles open up the market by establishing Bahai sales network.
