리튬 이온 배터리의 성능을 향상시키는 BNA. Posted by batterymanufactory.com

Recent research published in a paper in NANO by a group of researchers from Northeastern University investigate the effect of hierarchical Bi2MoO6 nanosheet arrays growing on three-dimensional Ni foam synthesized by one-step template-free route. The obtained BNAs used directly as binder-free integrated electrode for Li-ion batteries (LIBs) exhibits a super high reversible discharge capacity of 2311.7 μAh/cm2, and an excellent cycle stability.

리튬 이온 배터리의 성능

With the rapid development of modern technology, a variety of portable electronic products have become the requirement of time. Li-ion batteries (LIBs) are the optimum selection by virtue of long cycle-life and high energy density properties. Meanwhile, LIBs are viewed as one of the most promising technology in various fields including the defense industry, space technology, electric vehicles and other fields. Nowadays, commercial LIBs mainly use graphite as the anode material. However, graphite can hardly provide the high capacity and high energy density necessary to satisfy the demand required for high power application of the next-generation LIBs due to its low theoretical specific capacity.

Thus, development of high-performance anode materials with high capacity as well as low insertion voltage is urgently needed. In terms of their high capacity, lots of metal oxides have attracted great interest in recent years. However, most metal oxides have low conductivity, high desertion voltage and structural instability, which result in poor rate capability, low power density and poor cycling stability. These shortcomings limit the application of metal oxides as anode materials for LIBs.

Among the numerous metal oxides, Bi2MoO6 with high theoretical capacity (791 mAh/g) and low desertion voltage (<1.0 V) has been widely studied for its excellent photoelectric properties, but, there are few reports on the nanostructure Bi2MoO6 as anode material for LIBs, not to mention the Bi2MoO6 integrated electrode.

Thereafter, developing an effective strategy to prepare the Bi2MoO6 integrated electrode and then exploring their electrochemical performance toward lithium is of great importance. To tackle the issue of low intrinsic conductivity, inferior cycling stability for Bi2MoO6 as anode material, the researchers proclaim an effective strategy to the synthesis of hierarchical Bi2MoO6 nanosheet arrays (BNAs) on the three-dimensional (3D) Ni foam by one-step template-free hydrothermal method. Remarkably, BNAs-integrated electrodes exhibit excellent electrochemical properties (a super high reversible discharge capacity of 2311.7 μAh/cm2, more than 500 times of cyclic stability), when used as the anode electrode for LIBs.

Undoubtedly, this work disclosed a new comprehension for improving the performance of LIBs with metal oxides as the anode material. It can improve the cycle stability and capacity of lithium-ion battery and is expected to be used in portable electronic devices in the future.

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...
