How to choose lithium battery?

Russian president demanded that exports of Russian gas to "unfriendly" countries be settled in rubles. The demand has raised concerns in Germany about possible supply disruptions and the impact on industry and households if utilities do not pay in robles. Europe gets about 40% of its gas from Russia. Last year, Europe imported about 155 billion cubic meters. Germany, Europe's largest economy, depends heavily on Russian gas.

The chief executive of Germany's E.ON said the German economy would face "significant damage, which should be avoided if possible" without Russian supplies. He also said it would take Germany three years to wean itself off Russian gas.  

In the event of a supply disruption, Germany's gas network regulator would prioritize home heating over industrial use, so energy-hungry manufacturers such as steelmakers would be the first to suffer, he said.

The volatile international situations will continue to affect the markets and prices of many commodities like the lithium battery.

Lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries. The electrolyte of lithium-ion batteries is fluid, so they are more unstable than lithium-polymer batteries, and they may explode if they are beaten by external forces or use substandard chargers. Many portable electronic products such as mobile phones and laptops use lithium batteries. In other words, many people have a "bomb" by their side. You must pay attention to the following points for safety reasons when purchasing.

1. Is there a clear indication of the capacity? Batteries that do not have a marked capacity (e.g. 1000mAh or 1000mAh) are likely to be of poor quality or recycled. Many cheap batteries on the market are made of recycled battery cores. Although the price is low, the lifespan is short, and the quality is unstable. Careless use may damage the phone.

2. There is no guaranteed standby time. Standby time refers to the continuous use time after the battery is installed in the mobile phone to the subsequent charging. Generally, the batteries sold on the market cannot guarantee the standby time for customers. This is because the quality of the batteries is unstable. Many cheap batteries use poor quality battery cores, so the standby time is short.

3. Whether to install a safety protection circuit board. Without a protective circuit board, the lithium battery is at risk of deformation, leakage and explosion. Under the vicious price-cutting competition, various companies seek lower-priced protection circuit boards or omit this device, making the market full of lithium batteries with a danger of explosion. Consumers cannot tell whether there is a protective circuit board from the appearance, so it is best to choose a reputable merchant to buy.

On January 19, 2022, The Ministry of Industry and Information Technology will guide relevant units to speed up the formulation of lithium battery coding standards.

Lithium primary battery

manganese dioxide

With metal lithium as the negative electrode and heat-treated manganese dioxide as the positive electrode, the separator is made of PP or PE film. The cylindrical battery is the same as the lithium ion battery separator. The electrolyte is an organic solution of lithium perchlorate, cylindrical or a button type. . The battery needs to be produced in a dry environment with a humidity of ≤1%.

Features: low self-discharge rate, annual self-discharge can be ≤ 1%, fully sealed (metal welding, laser seal) battery can meet ten years of life, the semi-sealed battery is generally five years, if the work control is not reasonable, it can not reach this life. Yiwei, which has done an excellent job developing cylindrical lithium-manganese batteries, has realized automatic production. The battery can be tested for short-circuit and over-discharge without explosion.

Generally, there is a button-type lithium battery on the motherboard of a desktop computer, which provides a weak current and can be used generally for about three years. Some hotels also use lithium-manganese dioxide batteries for access control cards, instruments, etc., which are used year by year decline.

Thionyl chloride

With metal lithium as the negative electrode, the positive electrode and the electrolyte are thionyl chloride (thionyl chloride), the cylindrical battery has electricity after assembly, and the voltage is 3.6V. quality) battery with the highest capacity. It is suitable for electronic instruments and equipment that cannot be maintained frequently and provides good current.

Other lithium batteries include lithium-ferrous sulfide batteries, lithium-sulfur oxide batteries, etc.
