How to order and request for quatotion, lead time ?
  • How to order?
    Get an answer before you buy. Whether a quote or a specification request from our lipoly battery section, you can count on our lighting fast follow up. We do not provide telephone support, the reason being that it is impossible to offer a quality product at an attractive price or answer your questions without making some compromises. We have decided to compromise on human resources rather than the technical.
  • Quotation
    Tell us the quantity you want to order by e-mail.
    The price depends on the quality of your order.
    Also we accept the small order for startup phase company or new project.
  • Lead time
    The regular lead time of lipoly sample or small order is 3-5 working days.
  • Shipment
    UPS/DHL/FedEx Door to Door.
What is room to swell of lipoly battery?
Lipoly Battery will have a sligh swell in the charging. So it will affects your mechanical design? The answeri we gave is that you do not have this worry about these.
Because all lipoly battery we produced have reasonable tolerances:

Thickness tolerances is ± 0.3mm,
length is ± 1.0mm,
width is ± 0.5mm.

What’s more, the swell usually only affects the thickness of the battery, and it is within our tolerances. It means that thickness tolerances is ± 0.3mm (Maximum tolerances is ± 0.5mm), that is swell range.

What is the life cycle of lipoly battery (Self-discharge) ?
  • Standard: After 500 cycles, the capacity will be <80%.
    It will be affected by the situation of discharge/recharge, and battery environment like temperature, humidity.
  • Temperature range:
    Charge: 0 to + 45 ° C
    Discharge: -20 to + 60 ° C
    Charge retention / Storage:
    1 year at -20 to 20 ° C> 70%
    3 month at -20 to 45 ° C> 70%
    1 month at -20 to 60 ° C> 70%
    If the temperature is too low, the capacity will be significantly reduced;
    If the temperature is too high, the battery is prone to internal short circuit;
    In addition, we can make encryption that are suitable for low temperature or high temperature, but need to re-create and use a special electrolyte.
  • LiPoly Batteries that lose 20% of their capacity must be removed from service and disposed of properly.
    Discharge the battery to 3V/Cell, making sure output wires are insulated, then wrap battery in a bag for disposal.
  • Product Warranty: Product warranty is limited to original defects in material and workmanship for 90 days from the day of purchase. Warranty does
    not cover collateral damage, misuse, abuse, incorrect charging and other inappropriate use of this product.
Analysis the loss capacity of lipoly battery.
  • After analysis the loss capacity of lipoly battery, we got the main reason is overcharge that charging voltage is over the prescriptive voltage (4.2V) and then keep charging. In this process of overcharge will result in loss capacity of lipoly battery. The main points are as follow
  • The overcharge of graphite anode of lipoly battery
    The overcharge of positive reaction of lipoly battery
    The oxidizing of electrolyte when overcharging
    Lithium ion will be easy deposited on the cathode and stop lithium ion implanted. The efficiency of discharge and capacity of lipoly battery will be lost.
  • The circulatory lithium ion will be reduced.
    The deposit lithium ion of metal will be reacted with electrolyte to Li2CO3 and LiF.
    The lithium ion of metal will be happened between negative and septum, and it may increase internal resistance of lithium polymer battery.
    Rapid charging is anther way to loss capacity of lipoly battery. When we doing rapid charging lipoly battery, discharge current is high, polarization will be happened on cathode, lithium ion will deposit obviously. The main reason of loss capacity of lipoly battery when we rapid charging is the matter of electronic chemical inertness, such as Co3O4, Mn2O3 and so on. They break the balance of capacity between cathode and anode. But the losing capacity of lipoly battery is irreversible.
  • Self discharge of lipoly battery is the losing capacity when the battery is not using. It have two condition when self discharge happened. No.1 is reversible losing capacity and No.2 is irreversible losing capacity. Reversible losing capacity is the capacity of lipoly battery will be recovered in next charging. Irreversible losing capacity is that the capacity of lipoly battery can’t be recovered in next charging. The influencing factor have the material of cathode/anode, technology, temperature and so on.
what’s discharge rate and charge rate for lipoly battery ?
  • The discharge rate is 0.5C-2C
  • Peak discharge: 2C
  • If you want High-rate discharge, please contact us. We also have stock some 3C-5C lipoly batteries.
Can the lipoly battery be certified for special requirements, such as IEC62133 ?
Yes, the additional certification is possible for medium-to-high volume projects but more time and effort is involved. Please discuss your individual requirements with your LiPoly Battery representative.
