New battery materials available! The "bombing machine" savior came?

For smart phones, the battery life has been the selling point of the product, not only is the battery life, even the most basic security problems also arise, which means that the battery needs reform? Recently, Northwestern University researchers discovered a new material called COF (Covalent Organic Framework), which will likely break the current status of lithium battery-led mobile devices.

The team led by William Dichtel is currently working on COF research, and they have also made quite a bit of upfront investment. "COF (covalent organic framework)" was crystal structure, this structure is precisely formed for storing electrical energy pores, contribute to the conductive material filling. The study found that the new material can withstand tens of thousands of charge-discharge cycles, the overall capacity of 10 times the traditional material, and recharge rate can be up to 15 times.

In addition to Northwestern University, commercial companies such as Samsung, Apple and Tesla are also striving to improve their battery products in an attempt to increase their storage capacity while reducing weight. A battery company called Amprius even uses nanotechnology in battery technology, using silicon and sulfur to create a very complex electrode structure that ensures that the battery can outgrow standard products in terms of capacity and speed. Regardless of how to improve the charging speed and endurance, or suggest that manufacturers have to invest in the most basic security issues, the future of the battery there is still a long way to go.

How Does 5-axis CNC MILLING WORK?


Milling is the process of cutting and drilling material using a rotating cylindrical tool. This tool is held in a spindle and comes in a variety of sizes and forms. With 5-axis machining, there have two extra rotary axes defined by A, which rotates around the X axis, B, which rotates around the Y axis, and C, which rotates around the Z axis. The combination of additional axes depends on the machine and comes in variations, including AB, AC, or BC.
With 5-axis machining, the table or cutting tool can be tilted, creating the ability to avoid collision with the tool holder and allowing for better access to part geometry. This also ensures improved tool life and cycle time as it helps maintain cutting position and constant chip load. This type of machining offers a push toward single-setup machining, creating shorter lead times and increasing efficiency.
CNC milling is complex machining technique which utilizes several types of pre-programmed CAM and CNC controls to build customized components or parts. We are professional custom CNC milling company and 5 Axis CNC Milling Service provider in China, we offer the manufacturing of precision machined parts and solutions at affordable rates to meet the growing demands of the clients across the world.
