the Difference between Power Lithium Battery and Ordinary Lithium Battery
Power lithium battery and ordinary lithium batteries are two common types of lithium batteries, which have some differences in application, design, performance, etc. This article will introduce the differences between power lithium batteries and ordinary lithium batteries, so as to help readers better understand these two types of lithium batteries.
1. Use difference
- power lithium battery: The power lithium battery is mainly used in electric vehicles, unmanned aerial vehicles, electric tools and other occasions that require high power output and long cycle charging and discharging. Power lithium battery has high energy density and power density, which can provide continuous and stable power output.
- Ordinary lithium battery: ordinary lithium batteries are mainly used in portable electronic products, mobile communication equipment, digital cameras and other occasions that require small power and lightweight. Ordinary lithium batteries usually pay attention to energy density and safety, but do not need to bear the requirements of high power output and long-term cyclic charge and discharge.
2. Differences between design and structure
- power lithium battery: power lithium batteries usually use thicker positive and negative electrode sheets and larger electrolyte capacity to provide higher current output and longer cycle life. The design of power lithium battery pays more attention to high power output and cycle stability.
- Ordinary lithium battery: ordinary lithium batteries usually use thinner positive and negative electrode sheets and smaller electrolyte capacity to provide higher energy density and lighter appearance. The design of ordinary lithium batteries pays more attention to energy density and lightweight.
3. Performance differences
- power lithium battery: power lithium battery has high discharge current and cycle life, which can provide stable high power output. The power lithium battery has low internal resistance and high discharge efficiency, and is suitable for applications requiring high performance and high power.
- Ordinary lithium battery
4. Security differences
- power lithium battery: higher safety requirements are usually considered in the design of power lithium batteries, and more safety measures and protection devices are adopted to prevent safety problems such as overcharge, overdischarge and short circuit.
- Ordinary lithium battery: the safety design of ordinary lithium batteries is relatively simple, and basic protection circuits are usually adopted, which may be less safe for long-term high-power output or harsh environment.
5. Cost difference
- power lithium battery: because the power lithium battery requires higher power output and cycle life, its manufacturing cost is relatively high. The price of power lithium batteries is usually higher than that of ordinary lithium batteries.
- Ordinary lithium battery: The manufacturing cost of ordinary lithium batteries is relatively low, which is suitable for large-scale production and popularization. The price of ordinary lithium batteries is relatively cheap.
By understanding the differences between power lithium batteries and ordinary lithium batteries in terms of application, design, performance, etc., the appropriate type of lithium batteries can be selected according to specific requirements. Whether it is used for power applications with high power output or portable devices with high energy density requirements, there are corresponding lithium battery types to choose from.
