General Information

• The SUNSYNK-L3.0 battery is not fully charged when shipped. We recommend installing within three\ months after arrival;

• During the maintenance process, do not re-install the batteries in the SUNSYNK-L3.0. Otherwise, the performance of the product will be reduced;

• It is forbidden to dismantle any battery in the SUNSYNK-L3.0, and it is not permitted to dissect the battery;

• After the SUNSYNK-L3.0 battery is over-discharged, we recommend charging the battery within 48 hours.
  The SUNSYNK-L3.0 can also be charged in parallel. After connecting the batteries in parallel, the charger needs to connect to the output port of any SUNSYNK-L3.0.

• Never attempt to open or dismantle the battery! The inside of the battery does not contain serviceable parts.

• Disconnect the SUNSYNK-L3.0 Li-Ion battery from all loads and charging devices before performing cleaning and maintenance activities

• Place the enclosed protective caps over the terminals before cleaning and maintenance activities to avoid the risk of contacting the terminals.

Inspection

Inspect for loose and/or damaged wiring and contacts, cracks, deformations, leakage, or damage of any other kind. If you find any damage to the battery, it must be replaced.

• Do not attempt to charge or use damaged batteries.
• IMPORTANT: Do not touch the liquid from a ruptured battery.

Regularly check the battery’s state of charge. Lithium Iron Phosphate batteries will slowly self-discharge when not in use or whilst in storage. Consider replacing the battery with a new one if you note either of the following conditions:

• The battery run time drops below 70% of the original run time.
• The battery charge time increases significantly.

Cleaning

If necessary, clean the Li-Ion battery with a soft, dry cloth. Never use liquids, solvents, or abrasives to clean the Li-Ion battery.

BATTERY RECOVERY

Aluminium, copper, lithium, iron, and other metal materials are recovered from discarded LiFePO4 batteries by the advanced hydro-metallurgical process. The process can reach a recovery efficiency of up to 80%. Next, the process steps are presented

Recovery Process and Steps of Cathode Materials

Aluminium foil as a collector is amphoteric metal. Firstly, it is dissolved in NaOH alkali solution to make aluminium enter the solution in the form of NaAlO2. After filtration, the filtrate is neutralized with sulphuric acid solution and precipitated to obtain Al (OH)3. When the pH value is above 9.0, most of the aluminium precipitates and the obtained Al (OH)3 can reach chemical purity after analysis.
The filter residue is dissolved with sulphuric acid and hydrogen peroxide. Thus, lithium iron phosphate enters the solution in the form of Fe2 (SO4) 3 and Li2SO4, separated from carbon black and carbon coated on the surface of lithium iron phosphate. After filtration and separation, the pH value of the filtrate is adjusted with NaOH and ammonia water. First, iron is precipitated with Fe (OH) 3, and the remaining solution is precipitated with saturated Na2CO3 solution at 90ºC.
Since FePO4 is slightly dissolved in nitric acid, the filter residue is dissolved with nitric acid and hydrogen peroxide, which directly precipitates FePO4, separates impurities such as carbon black from the acid solution, leaches Fe (OH) 3 from filter residue respectively, and precipitates Li2CO3 with saturated Na2CO3 solution at 90ºC.

Recovery of Anode Materials

The recovery process of anode materials is relatively simple. After the anode plates’ separation, copper’s purity can be more than 99%, which can be used to further refine electrolytic copper.

Recovery of Diaphragm

The diaphragm material is mainly harmless and has no recycling value.

List of Recycling Equipment

Automatic dismantling machine, pulverize, wet gold pool, etc.

TRANSPORTATION REQUIREMENTS

Transport the battery products just after packaging. It can be transported using cars, trains, and ships. Avoid exposing the packaging to severe vibration, impact, or extrusion during transportation. Also, avoid exposing the packaging to direct sunlight or rain.
Always check all applicable local, national, and international regulations before transporting Lithium Iron Phosphate batteries.
In some instances, transporting end-of-life, damaged, or recalled batteries may be especially limited or prohibited.
The transport of the Li-Ion batteries falls under hazard class UN3480, class 9. The battery falls within packaging group PI965 Section I for transport over water, air, or land.
