There are three types of lithium-ion batteries used in automobiles: lithium iron phosphate batteries, ternary lithium-ion batteries, and polymer batteries. Which one is easiest to use?
Ternary lithium-ion batteries, lithium iron phosphate batteries, lithium polymer batteries, and lithium iron batteries have relatively lower output current and higher safety (around 400 degrees Celsius). The safety temperature for ternary lithium-ion batteries has now reached 250 degrees Celsius, making both batteries quite safe in everyday production environments. Polymer batteries are the least safe of the three types because they are prone to expansion. In terms of battery capacity, ternary lithium-ion batteries weigh only 60% of lithium-ion batteries. The consistency of ternary lithium-ion batteries is generally over 95%, while lithium iron phosphate batteries have a maximum consistency of 40%. This means that only 40% of lithium iron phosphate batteries have the same performance as ternary lithium-ion batteries, guaranteeing 95% consistency. Therefore, ternary lithium-ion batteries are still the preferred choice for electric vehicles, as they are not composed of two separate batteries, and their consistency may not be as good.
(1) Lithium-ion batteries are rechargeable batteries made primarily of lithium cobalt oxide. They are characterized by high energy conversion, high voltage of each battery, and large capacity (for the same capacity). They are lightweight, have no memory effect, and are the most environmentally friendly batteries, but their price is higher than other batteries. While they have high energy density, they are generally not made into very large capacity batteries due to the risk of explosion and fire. However, with technological advancements and the rationalization of protection circuits, lithium-ion batteries are now used in modern electric vehicles. (2) Ordinary batteries are lead-acid batteries, mainly composed of lead plates. These batteries are large, heavy, and have a memory effect. Lead pollution is severe. Their advantages are low cost and the ability to combine high-capacity, high-voltage batteries. They are mainly used in automotive ignition batteries and backup power supplies for engine rooms. However, they also pose a fire risk. The country currently controls the production of these batteries by small and medium-sized companies to prevent the spread of pollution.
