subject: Lithium-ion battery materials, a high energy density batteries [print this page] NiMH batteries are nickel hydrogen ions and synthesis, power reserve of more than 30% nickel-cadmium batteries, lighter than nickel-cadmium batteries, has a longer service life and environmental pollution, no memory effect. Ni-MH battery drawback is the price a lot more expensive nickel-cadmium batteries, performance is worse than the lithium batteries.
Lithium-ion battery materials, a high energy density batteries. Lithium-ion battery or a smart battery that can meet with the special original smart charger, to the shortest charge time, the largest life-cycle and the maximum capacity. Lithium-ion battery is the best battery performance. With the same size nickel-cadmium batteries, nickel metal hydride battery compared to the maximum power reserve, lightest, longest, shortest charge time, no memory effect.
No memory effect greatly facilitates mobile phone users, users do not have to discharge before each charge and then when they charge, and can be arbitrary at any time on the phone charge. Dell inspiron 640m battery Dell inspiron b120 battery Dell xps m1210 battery Dell inspiron xps m1710 battery
Cycle Jiushi use, we are using the battery, concern is the use of time, to measure the battery's in the end can be a performance using multi Zhangshi Jian Zhe Yang, Jiu Liao Xun Huan provides the number of definitions. Actually the user to use the ever-changing, because Tiaojianbutong of test is not comparable, there must be more we must standardize the definition of cycle life.
GB so cycle life under test conditions and requirements: room temperature at 25 degrees under normal conditions in accordance with the IEC standards can charge up to 500-1000 week; by 1C charge and discharge performance of accelerated life testing, up to 300 - more than 600 weeks.
A. This definition provides a deep-cycle life testing is conducted in a way full of deep discharge
B. In accordance with the provisions of the cycle of life, after the implementation of this model to more than 300 times since there are still more than 60% capacity
