Why we need a polymer lithium-ion battery ?

Friday, September 21, 2018 1:05:12 AM America/Los_Angeles

In the past ten years, with the rapid development of communication technology, mobile phone color screen technology, MMS technology, Bluetooth technology and camera technology have appeared successively, which puts higher requirements on the capacity, volume, weight and electrochemical performance of the battery. Traditional liquid lithium batteries have become increasingly unable to adapt to new demands. The emergence of a new polymer lithium-ion battery (Li-Polymer) caters to this demand.

Frequently Asked Questions about Lithium Battery

Monday, September 17, 2018 8:40:03 PM America/Los_Angeles

Overcurrent and short circuit current

An overcurrent or short circuit is caused by an unknown cause (when the battery is discharged or the positive and negative electrodes are accidentally touched by metal). To ensure safety, it is necessary to stop the discharge immediately.

These lithium-ion batteries can't catch fire because they harden on impact

Thursday, August 23, 2018 7:54:55 PM America/Los_Angeles

Lithium-ion batteries used in consumer electronics are notorious for bursting into flame when damaged. These incidents occasionally have grave consequences, ranging from burns to house fires to the crash of an airplane. Inspired by the weird behavior of some liquids that solidify on impact, researchers have developed a practical and inexpensive method to prevent these fires. They will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.

Performance And Test Conditions of Lithium Battery

Wednesday, August 22, 2018 9:28:21 PM America/Los_Angeles

Standard Test Conditions:

Test should be conducted with new batteries within one week after shipment from our factory and the cells shall not be cycled more than five times before the test. Unless otherwise specified, test and measurement shall be done under temperature of 20±5℃ and relative humidity of 45~85%. If it is judged that the test results are not affected by such conditions, the tests may be conducted at temperature 15~30℃ and humidity 25~85%RH.

Expanding the limits of Li-ion batteries: Electrodes for all-solid-state batteries

Tuesday, August 14, 2018 10:19:14 PM America/Los_Angeles

Scientists have addressed one of the major disadvantages of all-solid-state batteries by developing batteries with a low resistance at their electrode/solid electrolyte interface. The fabricated batteries showed excellent electrochemical properties that greatly surpass those of traditional and ubiquitous Li-ion batteries; thereby, demonstrating the promise of all-solid-state battery technology and its potential to revolutionize portable electronics.

Looking inside the lithium battery's black box

Thursday, August 2, 2018 7:49:37 PM America/Los_Angeles

Researchers report the use of SRS microscopy, a technique widely used in biomedical studies, to explore the mechanism behind dendrite growth in lithium batteries, the first team of material scientists to directly observe ion transport in electrolytes. They were able to see not only why lithium dendrites form but also how to inhibit their growth. Visualizing ion movement could help improve the performance of electrochemical devices, from batteries to fuel cells to sensors.
