The future lithium ion battery (laptop ac adapter) would be more safe

Normal,strict,careful and safe design in battery factory

First, in order to attanining the safe laptop ac adapter battery 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 battery 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 laptop ac adapter 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 laptop ac adapter battery 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.
