Influences of Temperature ranges on Material of Lithium Ion Batteries

Published Date: 2017-07-28 01:30 Category: News Center

With the increasing demand for energy, people on the battery requirements are also rising, many products require the battery can work in a variety of extreme conditions. Lithium-ion batteries as a new energy storage teced in every aspect, including product R&D, supplier management, material control, product process control, finished Shipping and after-sales service.

We adhere to the customer-oriented requirements, to provide customers with satisfactory products with pragmatic and rigorous attitude, to provide customers with products beyond the expectations with innovative technology and craftsmen spiri/d/Uploadfile/image/20170728/20170728033715391539.jpg" alt="" width="450" height="330" title="" align="" />

1. The cathode material

Positive electrode is the transit center of lithium ion and electron, it is easy to phase change. On the other hand, in the case of deep cha( ( #`|l"pl"Y"T"S"j"j"@h|Hl" l"h|hX d rging, the side reaction at the electrode-electrolyte interface tends to cause the electrode structure to become unstable.

2. The anode maerred to as the delay time and the lowe#`|( ( Xe|j"j"Y"T"S" T" T"g|j"j"ign:justify;"> (2). Positive and negative compaction

If the positive and negative compaction is too high, it can reduce cycle performance of tgeFeatures:

High and stable operating voltage: standard voltage is 3.6V and the operating voltage throughout the life of the period to maintain a significant stable.

Better storage life and reliability: with low self-discharge characteristics, the annual self-discharge rate 2%, while its use of stainln be recycled. In addition, high compaction of positive and negative is hard to ensure the high preserving fluid volume. Preserving fluid volume is the basis of cell to cycle normal or more cycle times.

gmn mercury, cadmium, lead and other heavy metals, no environmental hazards.

Good sealing performance: Li-SOCl2 battery is fully sealed battery. The battery cover is welded to the battery casen

(3). Excessive negative

As for lithium cobalt oxide added graphite system, graphite cathode becomes short boarde/image/20170525/201terial

The work of the negative electrode material is often dependent on the effective passivation layer, which will cause the passivation structure to be destroyed and cause side reactions, and the decrease in temperature will reduce the permeability of lithium ions.

3. The electrolyte

Under low temperature conditions, the electrolyte viscosity increases, hinder ion migration and electrode wettability, reduce the ratio of performance, in addition, the conductivity will cause the electrode around the lithium ion consumption. Under high temperature conditions, the electrolyte is susceptible to chemical changes and reacts with the charged electrode.

4. Other materials

In addition to cathode materials, anode materials and electrolyte materials, lithium-ion batteries also have some auxiliary materials, such as diaphragms, adhesives and current collectors and so on. Although these materials are hardly electrochemically active, they are rarely studied, but they are also important factors that protect the battery from working properly under extreme conditions.
