VRLA-AGM Battery for Telecom Applications
LEOCH VRLA-AGM batteries are Valve-Regulated Lead-Acid batteries with Absorbed Glass Mat (AGM)
separators. Since1994, LEOCH has made rapid progress by using matured
technology invented more than half a century ago. LEOCH is now able to
design, build and market high quality, long life VRLA-AGM batteries from
2V to 24V, and 0.5AH to 3500AH. LEOCH produces batteries from scratch
and is capable of engineering tools and molds upon our customer’s
request. LEOCH is now one of the fastest developing lead-acid battery
manufacturers in the world.
-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
High Temperature Battery
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.
LEOCH Gel VRLA batteries are
building on our experience in AGM VRLA batteries.
LEOCH battery completely relied on its own technology and strength, and
has successfully developed LEOCH GEL battery. Through simulation and
speedup tests,it has shown good effect, and LEOCH GEL battery’ every
quality indicator has reached the advanced overseas level and has become
a series production.
Lead low-antimony positive plate can
effectively prevent shedding of active material. The spines are casted
by multi-alloy, of which
the crystals are very fine and compact, in order to achieve excellent
corrosion resistance and long cycle life. Negative flat plates are
pasted plates with wavy construction, greatly improving the utilization
rate of active material and high current discharge property. Also the
charging acceptance ability is very good.
Lithium Ion Battery
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
