CASIO NP-60 Digital Camera Battery,New,600mAh, 3.7V, Li-ion, Casio Battery Pack
Zanasil
First, in order to attanining the safe casio np-60 battery(np-60|np60)
investigate index,need to adopt regular anode or cathode material and
guarantee the surfeit in designing the minus. The lithium ion can
embed and emerge at the anode and cathode pole of the samdwich under
the normal charging and discharging situation,commonly, will not cause
the damage of the crystal structure and also will not become a crystal
to pierce the diaphragm to make inner part short-circuit.
In the production line, the factory still need strictly control the
pole slice consistency,preventing lithium ion gather on the surface of
the minus pole, simultaneity adopting the battery septum with the hot
close characteristic,the PE film hole in the two side of the compound
film will close,the lithium np-60 resistance will augment,temperature
will get up slower when the temperature up to 120℃; Should add
something for preventing over charge in the electrolyte,when the
voltage over the rating voltage, the additive will converge, add the
battery resistance quickly and lower the battery fever quantity; The
casio battery np-60 lithium ion battery should have the safe valve,the
safe valve can open to leak to press etc. when the internal pressure
is bigger than the certain value.
Moreover, the control of the manufacturing environment is also very
important, because the impurity led in the manufacture can cause the
lithium casio camera battery np60 safe problem. End, the each battery
cores still need to make many abuse trial test,such as over charge,hot
box,pinprick, squeeze, the temperature pound, exterior short circuit,
drop into the etc., investigating its safe function very well.
