1. Capacity. Capacity refers to the amount of electricity that a LiFePO4 battery can release during a single charge and discharge process, usually expressed in ampere hours (Ah) or milliampere hours (mAh).
2. Energy density. Energy density refers to the electrical energy stored per unit mass or volume of a LiFePO4 battery, usually expressed in watt hours per kilogram (Wh/kg) or watt hours per liter (Wh/L).
3. Cycle life. Cycle life refers to the number of times a LiFePO4 battery can undergo charging and discharging cycles without failure under specified conditions, usually expressed in terms of times or years.
4. Charging and discharging efficiency. The charge/discharge efficiency refers to the ratio of the output electric energy to the input electric energy of a LiFePO4 battery during a single charge/discharge process, usually expressed as a percentage.
Electric vehicles refer to vehicles powered by electric energy and driven by electric motors. Compared to traditional internal combustion engines, they have advantages such as energy conservation, emission reduction, low noise, and low operating costs. One of the core components of electric vehicles is the power battery, which determines the range, charging and discharging speed, safety performance, etc. of electric vehicles. Currently, the main types of power batteries used in the market include nickel hydrogen (Ni-MH), nickel cobalt aluminum (NCA), nickel manganese cobalt (NMC), ternary materials (NCM), lithium titanate (LTO), and lithium iron phosphorus (LFP).
The lifepo4 battery is often used in applications where safety is a concern, such as electric vehicles and energy storage systems. LifePo4 batteries also have a relatively low energy density compared to other types of lithium-ion batteries, which means they may not be suitable for applications that need to store a lot of energy in a small space.
One of the main advantages of lifepo4 batteries is their high energy density, which allows them to store large amounts of energy in a small volume. They also have a relatively long lifespan and are resistant to the effects of overcharging, making them a popular choice for a variety of applications.
Combining CATL, EVE, GOTION, Great Power, ATL's etc. world-class lithium cell supply resources with professional safety battery PACK packaging technology, Rongke provides an efficient, one-stop shop for all our customers' energy storage needs. Using thousands kind cell specifications, we can deliver a wide range of battery size and capacity solutions to meet the needs of Battery Energy Storage & Systems, from customized design and manufacturing to certification, sales, service and more.
Optimal product safety is the foundation of everything we do. When designing products, we apply multi-dimensional (structural, electrical and thermal) redundant safety protection via scientific tools such as FMEA (Failure Mode and Effects Analysis) and simulation. We adopt at RSD' life prediction system combined with rigorous safety management to supervise the life-cycle conditions of our products. We also collect, analyze and archive all supervision data to ensure our users can rely fully on the safety of our products.
At this stage, 5,000 square meters have been put into use, with a monthly production capacity of 5 million US dollars. The second phase of the factory building is planned to add 5,000 square meters in the second quarter of 2023, and the monthly production capacity will reach 10 million US dollars by then. The third phase of the plant plans to add another 5,000 square meters in the fourth quarter of 2023, and the monthly production capacity will exceed 15 million US dollars.
LiFePO4 battery is a lithium ion battery using lithium iron phosphorus (LiFePO4) as the positive electrode material, with graphite carbon electrode and metal back plate as the negative electrode. LiFePO4 batteries have the advantages of high energy density, long life, low maintenance, and high safety, and are suitable for various fields and scenarios, such as solar energy storage systems, electric vehicles, and portable devices.
The charge and discharge process of LiFePO4 batteries is a reversible electrochemical reaction, in which lithium ions move back and forth between the positive electrode and the negative electrode, accompanied by the flow of electrons. During charging, lithium ions are released from the positive electrode (LiFePO4) and moved through the membrane to the negative electrode (graphite). At the same time, electrons flow into the negative electrode from an external power source, making the negative electrode negatively charged. During discharge, lithium ions are released from the negative electrode (graphite) and moved through the membrane to the positive electrode (LiFePO4). At the same time, electrons flow out of the negative electrode and into the positive electrode through external loads, making the positive electrode positively charged.
