How to understand high rate polymer lithium battery

Time:2020-12-25 Views:228

  High-rate polymer lithium battery, let's first understand the concept of rate. How to understand the discharge rate? Discharge rate refers to the current value required by the battery to discharge its rated capacity within a specified time. The data value is equal to the multiple of the battery's rated capacity, usually represented by the letter C. Generally speaking, if the C number is greater than 1, it means a high rate. High rate is a relative concept. The larger the C number of a lithium battery, the higher the rate of the battery.

  The concept of polymer lithium battery

  Next, talk about what is a polymer lithium battery. Its full name is polymer lithium ion power battery, which is a kind of lithium ion battery. Lithium-ion battery is a high-rate rechargeable battery, which mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ is intercalated and deintercalated back and forth between the two electrodes: when recharging the battery, Li+ is deintercalated from the positive electrode and inserted into the negative electrode through the electrolyte, the negative electrode is in a lithium-rich state; the opposite is true during discharge.

  Combining high-rate and polymer lithium batteries means that polymer lithium-ion power batteries with a large discharge C number are high-rate polymer lithium batteries. They are generally not used in digital products such as mobile phones, but are used in those who need Explosive electric vehicles, various model airplanes and remote control model vehicles, etc.

  High-rate polymer lithium battery brand

  High-rate polymer lithium batteries require a large discharge C number, but not every factory produces a high rate of lithium batteries. There are various lithium batteries, and the batteries of lithium battery manufacturers are also very different. In strategy and technology Each has its own focus. At present, the Grignard battery produced by Gripp Battery also has many high-rate polymer lithium batteries, and the battery life is relatively long. It is well-known in the aircraft model industry for its battery cell technology and battery durability. In addition, there are some other brands of high-rate lithium batteries, which will not be introduced one by one again.

  As we all know, the price of high-quality lithium batteries is not cheap. The high-rate polymer battery has strong power and provides racing power for competitive remote-controlled cars and model airplanes. This also has a large loss of battery, and the service cycle is relatively low compared to other rates. The battery is short, so it is also necessary to pay attention to the service life of these high-rate lithium batteries. It is a wise choice to choose high-rate polymer lithium batteries that have a longer cycle of use.
