12V LFeLi Battery offers up to 20 times longer cycle life and five times longer float/calendar life than lead acid battery, helping to minimize replacement cost and reduce total cost of ownership.
Detail
Lithium iron Phosphate battery (LiFePO4) has a nominal voltage of 48VDC. It is comprised by 16 cells of 3.2V each. The internal structure of LiFePO4 battery cell is shown in the figure on the right. Shown is the olivine structure of LiFePO4 as the positive electrode of cell. Aluminum foil functions as current collector of positive pole. A polymer membrane separates positive and negative electrodes of the cell. The electron (e-) can't pass through the polymer separator but Li+ can pass through it freely. The negative electrode which consists of graphite is shown in the figure on the right. Copper foil is the current collector of negative electrode. There is organic electrolyte in the cell which is sealed by Al-plastic composite film.
Detail
Air-condition of communication base station is used to guarantee the equipments work normally. Wireless facilities, transmission facilities, power supply facilities work well at 40℃, but the lead acid battery which constitutes power supply is sensitive to surrounding temperature. The battery requires 25℃ operating temperature and its service life will reduce to half when temperature rises by 10℃. As a result, it is significant to develop a battery specially for communication, which is energy saving, lower emission, and has a longer temperature range and service life.
Detail
Pure Lead used to optimize the high rate and float life. Punched continuous grid strip – better metal crystal structure Continuous, double pasting process – high consistency and reliability High Temperature Curing for Standby application to improve cycling ability COS welding, TTP and ABS heat sealing - Low internal resistance and Low self-discharging rate rapid charging acceptance and cyclic endurance for a superior performance in extreme environmental conditions. Jar formation is involved which is more under Environment friendly consideration
