Why  choose  our  battery

AYJ  Factory

Full  automatic  production  line

Others

Small  Manufacturers,  handiwork

Automatic  production  line  avoid  the  quality  problems  
by  hand,  high  efficiency  with  good  quality

Bad  environment,  manual  operation,  it  is  easy  to  appear  
mistake  if  by  full  manual  operation,    low  efficiency,  bad  quality

AYJ  Battery  Cell

after  650  times  cycle  life

Others

after  100  times  cycle  life

The  surface  of  the  battery  cell  is  still  smooth,  thickness
 only  increase  0.1mm,  it  can  be  used  normally

There  will  be  particle  from  the  battery  cell  inside,  thickness  
increase  0.2mm,  easily  caught  fire  and  explode  the  screen

AYJ  welding  machine
                                                                                           

￥300,000  Laser  welding  machine    
                                                                                                                   

Others

￥2000  Foot-type  welding    machine

We  use  big  brand    Automatic  laser  welding  machine,
computer  control  to  make  sure  welding  precision,
fastness,  high  efficiency  with  good  quality

Foot-type  welding  machine,  melted  nickel  by  pressure,  
large  current  ,high  frequency,  high  temperature
High  frequency  is  easy  to  breakdown  the  separator  between
positive  pole  and  negative  pole.
Broken  the  protection  board  IC  to  led  fire  or  explosion
Pressure  by  foot  is  not  stable,  easy  to  crushing  damage  the
PCB

AYJ  FPC

after  3  times  bending  

Others

Common  FPC  after  3  times  bending

FPC  problem  is  the  most  often  problem  during  use.
AYJ  FPC  use  copper  foil  material  which  purchased  
from  public  company,  good  flexibility,  high  conductive,
excellent  heat  exchange  material.
XRM  FPC  can  bear  about  5KG  tension（pulling  force
 testing  Machine）
Greatly  reduces  FPC  break  off  problems.

Common  FPC  Easy  to  break  off  ,bad  flexibility  ,  low
conductive,  high  internal  resistance（FPC  high  resistance  will
cause  temperature  rise  when  FPC  overcurrent,  even  fire）
