1. Lithium Battery Electrochemical Theory and advantage
1.1.SES Battery Lithium Battery is a backup battery used for portable equipment and office and factory automation. The battery also working in conjunction with solar cells to make a decentralized power supply system.
1.2.Where “charge” is the operation of supplying the Lithium battery with direct current from an external power source to change the active material in the negative plates chemically,and hence to store the battery electric energy in the form of chemical energy,”Discharge” is the operation of releasing the electric energy from the Lithium battery to operate the external equipment and device.
1.3.SES Battery Lithium Battery is small and lightweight that gives high performance making it very economical to use. In addition to these advantages, the sealed construction eliminates the necessity to fill the battery with water.
2.Battery Construction
The construction of a Lithium battery is shown Figure 1. The following is a description of the different parts that make up our batteries.
(a) Positive and negative plates
Positive and negative plates consist of active
mass and a lead-calcium alloy grid structure.
(b) Separator
Unwoven glass fiber cloth, with a high oxidation
and heat resistance, is used to offer superior electrolyte absorption and retaining ability and satisfactory ion conductivity.
(c)Electrolyte
Diluted sulfuric acid is used as the medium for conducting ions in the electrochemical reaction in the battery

(e ) Container and covers
Container and covers are made of ABS or PP resin, with superior strength and acid resistance
characteristics. The container and covers are sealed to prevent electrolyte and gas leakage.
(f) Positive and negative electrode teminals
Positive and negative electrode terminals may ber fasten tab type,bolt fastening type,threaded
post type,or lead wire type,depending on the battery type,sealing of the terminal is achieved
by a structure which secures long adhesive-embedded paths and by the adoption of strong
expoxy adhesives.
CAUTION: ALWAYS USE A BATTERY BEST DESIGNED FOR THE APPLICATION.
This guide is focused on Industrial Standby applications and NOT Automotive or Traction use.

Product Applications:
BATTERY DISPOSAL/RE-CYCLING
Finally, when a battery has reached the end-of-life it must be returned to the point of sale or to a licensed battery dealer for recycling.
