Into 2002, today, the lithium-ion battery in the other cell phone handset manufacturers have also been widely used and popular. However, in polymer lithium-ion battery, but also far from all mobile phone manufacturers to get popularity of the product is widely used remains to be seen. On the other hand, although a lot of advantages of lithium-ion batteries, but there are shortcomings, such as charge and discharge times of high prices and less so. Lithium battery charge and discharge only 400-600 times, specially modified products, but 800 times. The nickel-metal hydride rechargeable battery can reach more than 700 times, some good quality product charge and discharge up to 1,200 times, such a comparison, the nickel-metal hydride battery live longer than lithium batteries. In addition, the price of nickel-metal hydride batteries is much lower than the lithium batteries. Moreover, strictly speaking, lithium batteries have the same memory effect, but it’s very low memory effect, basically negligible. Here is the anti-explosivecell phone jammer .
A new generation of polymer lithium-ion polymer battery technology is already very high degree, so the shape can be of thin (the thinnest 0.5 mm), and any area of any shape, greatly improved battery design flexibility , so it can meet the demand, made of any shape and capacity of the battery. Meanwhile, the polymer lithium ion battery unit of energy than the current lithium-ion batteries in general increased by 50% of its capacity, charge and discharge characteristics, safety, operating temperature range, cycle life and other aspects of environmental performance over a large lithium-ion battery rate increase. cell phone jammer can make all cell phone within the shielded range lose the signal within 1s.
Currently marketed liquid lithium-ion (LiB) over-charging the battery in the case, and therefore likely to cause safety valve ruptured fire situation, it is very dangerous, so necessary to ensure that the installation of the battery protection IC circuit does not occur over charge of the situation. The polymer lithium-ion batteries, this type of battery is relatively liquid lithium-ion battery has good resistance to charge and discharge characteristics, so outside unprotected IC circuit requirements can be relaxed. In addition, in charge, the polymer lithium-ion battery can be charged using constant current IC with Li-ion secondary battery used in CCCV (Constant Currert-Constant Voltage) charging time required for comparison, can shorten the waiting time for many cell phone jammer has no radiation towards the human body.
Although almost all manufacturers have in recent years tend to use lithium-ion battery, but the world’s major mobile phone manufacturers the choice of battery or have their own characteristics and habits, such as once in the same historical period: Nokia: The Ni- MH (nickel-metal hydride) battery, LiB (liquid lithium-ion) batteries, not the use of LiP (polymer lithium-ion) batteries. Ericsson: The Ni-MH battery, LiB battery, LiP batteries. Motorola: The Ni-MH battery, LiB battery, did not use LiP batteries. Not difficult to find, from the earliest use of mobile phones LiP polymer lithium-ion batteries on this matter, Ericsson reflect the true nature of their cell phone technology pioneer. According to the information I find that, at present polymer lithium-ion battery factory in Japan SONY, Panasonic, GS, several companies, produced in 2000 reached 21 million, of which 50% of Ericsson mobile phone support. 3g cell phone jammer is applicable to the location full of explosive gas compound.
