리튬 배터리

Lithium-ion battery characteristics

A. High energy density
The weight of lithium-ion battery is the same Capacity of nickel-cadmium or nickel-metal hydride batteries half, the volume is 40-50% of nickel-cadmium, nickel-hydrogen of 20-30%.

B. High voltage
A lithium-ion cell operating voltage of 3.7V (average), equivalent to three series of nickel-cadmium or nickel metal hydride batteries.

C. No pollution
Lithium-ion batteries do not contain harmful metals such as cadmium, lead and mercury.

D. Does not contain metallic lithium
Lithium-ion batteries contain no metallic lithium and are therefore not subject to the restrictions imposed by aircraft transport on the prohibition of carrying lithium batteries in passenger aircraft.

E. Cycle life is high
Under normal conditions, lithium-ion battery charge-discharge cycle can be more than 500 times.

F. No memory effect
The memory effect refers to the phenomenon that the capacity of the battery is reduced during the charge-discharge cycle of the nickel-cadmium battery, and the lithium ion battery does not have such effect.

G. Fast charging
The use of constant voltage and constant voltage charger with a rated voltage of 4.2V can make the Li-ion battery fully charged in one to two hours.

스마트폰을 위한 어떤 종류의 배터리가 더 좋은가요? Li-Ion 또는 LiPo?

Did you ever think about why your phone works at all? Probably not. But, if you think about it, all portable gadgets rely on a battery to keep ticking – and some have better battery life than others. That’s why we’re going to take a peek at what keeps your phone ticking and why some batteries do better than others. On the basis of chemistry used for ions carrying electrolyte material, Lithium battery can be classified into Lithium ion and lithium Polymer. Lithium ion battery uses liquid lithium ion as electrolyte while lithium polymer use solid or gelatin like polymers as electrolyte. Lithium ion batteries have high energy density and cost less than lithium polymer. Lithium polymer batteries are light weight and have improved safety . However their cost is high (30% average) as compared to lithium ion. Also the the energy density of Li-Polymer battery compared to Li-Ion Batteries is quite less. Lithium ion batteries tend to lose charge with ageing even when not us...

What is KC certification? The KC (Korea Certification) certification mark signifies compliance with Korea’s product safety requirements for electrical and electronic equipment and components that utilise power from AC 50-1000V. The KC certification procedure for products includes the following steps: 1. Application - The application process involves the submission of an application form and product description. In addition, the manufacture must obtain a certificate of registration. 2. Factory inspection - Production equipment and processes are inspected and audited for compliance with applicable safety criteria. 3. Product testing - The product is tested consistent with the requirements of the applicable safety standard(s). 4. EMC testing - The product is tested for electromagnetic compatibility (EMC) and immunity. 5. Post-certification surveillance - Regular factory inspections and market surveillance are required to verify continued compliance following cer...

신기술로 인해 배터리가 코발트에서 분리 될 수 있습니다. Posted by batterymanufactory.com

Lithium-based batteries use more than 50 percent of all cobalt produced in the world. These batteries are in your cell phone, laptop and maybe even your car. About 50 percent of the world's cobalt comes from the Congo, where it's largely mined by hand, in some instances by children. But now, a research team led by scientists at the University of California, Berkeley, has opened the door to using other metals in lithium-based batteries, and have built cathodes with 50 percent more lithium-storage capacity than conventional materials. "We've opened up a new chemical space for battery technology," said senior author Gerbrand Ceder, professor in the Department of Materials Science and Engineering at Berkeley. "For the first time we have a really cheap element that can do a lot of electron exchange in batteries." The study will be published in the April 12 edition of the journal Nature. The work was a collaboration between scientists at...
