What is the cycle life of lithium iron phosphate batteries?button cell battery cr1620

　　1、 Lithium iron phosphate batteries have different discharge rates in different environments:

　　Firstly, the editor would like to introduce that lithium iron phosphate batteries have different discharge rates in different environments, with the minimum discharge rate reaching 0.5c and the maximum discharge rate reaching 10c. Regardless of the discharge rate, this type of battery will be very flat during the discharge process. Generally speaking, the voltage is very stable and almost unchanged, only when the power generation of lithium iron phosphate batteries is about to end, It will only be discovered that it will experience a sharp decline, which can effectively demonstrate that lithium iron phosphate batteries have excellent discharge characteristics, indicating that their true lifespan is very long.

　　2、 Display of lithium iron phosphate batteries under different temperature conditions:

　　Secondly, the editor would like to introduce that lithium iron phosphate batteries also exhibit different discharge phenomena at different regulated temperatures. We set the temperature to -20 ° C to above 40 ° C. At this point, you will find that lithium iron phosphate batteries can generate 100% of their power at 23 ° C, while at 0 ° C, their discharge capacity is 78%, That is to say, the discharge rate of lithium iron phosphate batteries varies under different temperature conditions. Therefore, when estimating the performance of lithium iron phosphate batteries, it is important to keep them in a specific temperature range. This way, the estimated results are better than others. However, based on their performance under extreme temperature conditions, the true lifespan of lithium iron phosphate batteries is very long, It can achieve over 570 discharge cycles.

　　3、 Experiment on placing lithium iron phosphate batteries at zero voltage:

　　In the experiment of placing a lithium iron phosphate battery at zero voltage, you will find that after the battery is fully charged for 3 days, it continues to discharge in such an environment, and its capacity changes very little. This indicates that its capacity recovery is very good.What level of after-sales service can lithium batteries achieve?

　　In recent years, the production of lithium-ion bicycles in China has shown an upward trend. In 2013, the production of electric bicycles reached 35 million, of which 2.6 million were lithium-ion bicycles, a year-on-year increase of 52.9%. The penetration rate of lithium-ion bicycles in electric bicycles has increased to 7.4%. Since 2014, the market situation of lithium-ion bicycles has shown good performance compared to last year. In the first half of this year, its sales reached 1.98 million vehicles, a year-on-year increase of 67.8%, and its penetration rate was around 10%.

　　The future of light electric vehicles will definitely be dominated by lithium batteries, which is a consensus in the industry. However, incomplete after-sales service, inconsistent standards, and high prices have always been considered the three main reasons why lithium-ion bicycles have not been rapidly promoted in China. In addition to price factors being considered the biggest obstacle to promotion, neglected after-sales service often becomes a fatal injury for lithium-ion bicycle manufacturers.

　　Lithium battery manufacturers lack understanding of the electric vehicle industry, and their marketing methods and ideas for the electric vehicle industry are not right, especially for after-sales service. "Zhang Yajun, General Manager of Tianjin Meilixing Lithium Tram Technology Co., Ltd., said that for enterprises accustomed to consumer lithium batteries, it is difficult to identify with or have no understanding of after-sales service in the electric bicycle industry, So, within a decade, many lithium-ion battery manufacturers have attempted to enter the electric bicycle industry, but after a period of time, they have exited, including now that such problems still exist

　　With the introduction of favorable national policies, many lithium-ion bicycle manufacturers that focus on exporting have turned to exploring the domestic market since 2012, seeing the huge opportunities in the Chinese market.

　　According to data from the High Tech Lithium Battery Industry Research Institute (GBII), between 2013 and 2014, the compound growth rate of China's lithium battery bicycle production exceeded 50%, higher than the growth rate of electric bicycle production. As the price of lithium-ion batteries gradually approaches that of lead-acid batteries, relying on advantages such as superior battery performance and ease of use, it is expected that by 2016, the sales of lithium-ion bicycles in China will reach 10 million units, with a penetration rate of 22.2%.
