A lithium battery, known in English as "lithium battery," is a type of rechargeable battery that uses lithium ions as a key component of its electrochemistry. The English term for this technology is “lithium battery,” and it is widely used in various electronic devices due to its high energy density and long life span.
The definition of a lithium battery in English can be succinctly described as follows: A lithium battery is a type of battery that relies on lithium ions moving between the anode and cathode to generate electrical energy. This movement of ions is facilitated through an electrolyte that is typically a lithium salt in an organic solvent. The lithium battery’s construction allows it to store more energy in a smaller and lighter package compared to other battery types, such as nickel-cadmium or lead-acid batteries.
The term "lithium battery" in English directly translates to "锂电池" (lǐ diànchí) in Chinese. In technical contexts, you might encounter variations such as "lithium-ion battery" (Li-ion battery) or "lithium-polymer battery" (LiPo battery), depending on the specific type of lithium technology used. Each variation refers to the type of electrolyte and the battery's construction, influencing its performance characteristics and applications.
When discussing the technical specifications of lithium batteries in English, several key parameters are commonly highlighted:
1. Voltage: Lithium batteries typically have a nominal voltage of 3.7 volts per cell, which is higher than the 1.2 volts of nickel-cadmium (NiCd) batteries and the 2.0 volts of lead-acid batteries.
2. Capacity: Measured in milliampere-hours (mAh) or ampere-hours (Ah), the capacity indicates how much charge the battery can store. High-capacity lithium batteries can offer significant energy storage in compact sizes.
3. Energy Density: Lithium batteries have a high energy density, often ranging between 150 to 200 Wh/kg (watt-hours per kilogram), which allows them to provide more power per unit of weight.
4. Cycle Life: This refers to the number of charge and discharge cycles a lithium battery can undergo before its capacity significantly diminishes. Typically, lithium batteries can handle around 300 to 500 cycles.
5. Temperature Range: Lithium batteries operate effectively within a temperature range of approximately -20°C to 60°C (-4°F to 140°F), although performance can vary based on specific battery chemistry and design.
For those seeking detailed technical specifications and documentation in English, manufacturers often provide datasheets that include precise information on performance, safety standards, and usage guidelines. These datasheets are essential for engineers and designers who need to integrate lithium batteries into their products and systems, ensuring optimal performance and safety.
In conclusion, understanding the terminology and technical specifications of lithium batteries in English is crucial for anyone working with these advanced energy storage solutions. Whether you are dealing with their definition, translation, or technical specs, a comprehensive grasp of lithium batteries enables more informed decisions and effective use in various applications.
