What is sodium carboxymethyl cellulose? Sodium carboxymethylcellulose (also known as sodium carboxymethylcellulose, carboxymethylcellulose, CMC, Carboxymethyl, CelluloseSodium, and SodiumsaltofCaboxyMethylCellulose) is the most widely used and most widely used cellulosic species in the world Referred to as CMC-Na, it is a cellulose derivative with a glucose polymerization degree of 100-2000, and its relative molecular mass is 242.

First, use the voltmeter plus load to detect the battery storage capacity Detecting the battery storage capacity, it is difficult to be accurate only by using the voltmeter or the multimeter's voltage block without load to check whether the storage of the battery is sufficient When measuring voltage alone, the current consumption is extremely small, so there is no large voltage drop inside the battery, so the display voltage is not low, but if a considerable load is added, such as turning on the headlight (load current 10 to 15A), press The horn (load current 6 ~ 12A), the battery will make the light dim, the horn is hoarse, thus showing insufficient power storage.

Consistency: If the lithium battery pack with poor consistency has a protection board, its capacity will be the lowest according to the bucket principle, which will cause the entire battery pack to not fully discharge power due to one battery core The ground absorbs electrical energy, and over time, the life of the battery pack is short.

Carbon and alkaline batteries, which are often used in daily life, have different prices Ordinary remote control board can use carbon battery, and digital cameras, electric razors use alkaline battery, so how to distinguish alkaline battery and carbon battery is very necessary.

The positive electrode materials are mostly micron or nano-sized particles, which are very easy to absorb moisture in the air, especially the ternary material with high Ni content In the preparation of the positive electrode slurry, if the positive electrode material has high moisture content, the NMP absorbs water during the slurry agitation process, which causes the PVDF solubility to decrease, resulting in the slurry gel being frozen and affecting the processing performance.

The lithium ion battery cell is composed of positive and negative electrodes, an electrolyte and a separator It is a basic structural unit constituting a battery module and a battery pack.

Recently, related companies in the lithium battery industry have announced the first quarter of 2018 results, compiled 31 companies' performance, and analyzed the performance of different companies in the industry chain to find out the development trend of the battery industry in 2018 The following is the detailed performance: The top ten companies in the performance rankings are Tianqi Lithium, Tianci Materials, Han's Laser, Yanfeng Lithium, Hanrui Cobalt, Pioneer Intelligence, GEM, Shengyu Mining, Shanshan and Qitailai.

Along with new launch of BUICK VELITE6 plug-in electric hybrid vehicles approaching, GM group analyzed its power battery parsing system through the blue BUICK new energy technology public class The depth of analysis is even to the level of disassembling.

The full name of ternary lithium-ion battery is "ternary polymer lithium-ion battery", refers to the lithium-ion battery which anode material using nickel cobalt manganese acid lithium It is named according to the "positive pole material".

In 2017, battery market can be said a bustle, over hundreds of billions money rushed in; OEMs started a craze of self-built system; raw material price increases successively and so on All shows a sense of elusive helplessness.
