Are Car Batteries Lithium Batteries?

[DeDiana]

Currently, most cars still use lead-acid batteries instead of lithium batteries. Reasons why cars still use lead-acid batteries instead of lithium batteries: The compromise is largely due to "safety" factors. Although lithium batteries perform excellently, their stability is not very good. During high-current discharge, they may cause internal short circuits and lead to explosions. The second reason is high-current characteristics. Since cars require a large instantaneous current when starting, the battery pack needs to provide sufficient current amplification capability, which is precisely an area where lithium batteries are not proficient. Another important factor is low-temperature performance: lithium batteries operate very efficiently at room temperature, but in environments below -10 degrees Celsius, their discharge performance rapidly deteriorates. This makes them unsuitable for a wider range of usage environments, which is also a key reason why lead-acid batteries cannot be replaced at this stage. Most common driving habits that harm the battery: Using in-car electrical devices for extended periods while the engine is off. This is a situation many car owners frequently encounter in daily use and is also easily overlooked. For example, to save fuel, many drivers turn off the engine while waiting in the car and use the audio system to listen to the radio or watch DVDs. While this achieves the goal of saving fuel, it can deeply harm the battery.
