The safety of power lithium batteries, including lithium manganate and lithium iron phosphate, is not consistent and varies with different materials used in their construction. When compared to lithium batteries, lead-acid batteries have a relatively mature technology, making them safer to use. This is because their safety standards are higher than those of lithium batteries.
When it comes to environmental protection, lithium batteries are the clear winner as they do not cause any pollution. However, the use of lead-acid batteries can result in heavy metal lead pollution, which is harmful to the environment. This means that electric vehicles that use lead-acid batteries continue to contribute to environmental pollution, whereas those that use lithium batteries do not.
The reason why electric cars equipped with lithium batteries are generally more costly is due to the fact that the price of lithium batteries, despite having the same capacity, is more than double that of lead-acid batteries in the market. As such, many consumers are hesitant to consider purchasing an electric vehicle with a lithium battery due to the steep price tag.
The lithium battery possesses a mass ratio, volume ratio, and energy ratio that exceed those of the lead-acid battery by approximately 40%.
Compared to lead-acid batteries, lithium batteries have a significantly lower self-discharge rate of less than 3%. In contrast, the self-discharge rate of lead-acid batteries is much higher, ranging from 15-30%.
Currently, ordinary lithium iron phosphate batteries have a longer service life than lead-acid batteries. This is mainly due to its lack of memory effect when charged 1500 times, as compared to lead-acid batteries, where the memory effect is very obvious. After charging 1500 times, the storage capacity of lithium iron phosphate batteries is still at 85%, whereas lead-acid batteries can only be charged about 500 times before experiencing a significant drop in storage capacity. It is therefore expected that electric vehicles equipped with lithium batteries will have a longer battery life than those using lead-acid batteries.
When comparing lithium batteries to lead-acid batteries, it's important to note that the voltage platform of lithium batteries is higher, sitting at over 3V, while lead-acid batteries have a voltage platform of 2V. This difference allows lithium batteries to provide about 30% more electricity than high current discharge lead-acid batteries with the same capacity. Ultimately, this makes lithium batteries more efficient and beneficial in terms of providing power to various devices and systems.
With a battery life of over 500 years, this product is truly remarkable. Comparatively, lead acid batteries, which typically have a lifespan of around two years, rely on a memory-based charging and discharging process that is limited to around 400 cycles. In contrast, maintenance-free lead-acid batteries require very little water and do not need distilled water during use. Therefore, it is important to note that this battery is exceptionally durable and long-lasting.
