4 types of button battery cr2032 technology for electric vehicles

The development of electric vehicles is inseparable from the reform of batteries. Many articles have mentioned the problems that electric vehicles are currently facing, such as the button battery cr2032 life of electric vehicles and the inconvenience of charging. While we are complaining, is the button battery cr2032 technology of electric vehicles really stagnant? In fact, this is not the case. Major manufacturers are also constantly reforming the button battery cr2032 quality and capacity of electric vehicles. There are several types of batteries on the market: lead-acid batteries, lithium iron manganese phosphate batteries, lithium iron phosphate batteries, lithium cobalt oxide batteries and ternary polymer lithium batteries, etc., and the current button battery cr2032 life of electric vehicles has also been improved. So, what is the specific situation of current button battery cr2032 technology? Lead-acid button battery cr2032: Lead-acid button battery cr2032 is the most common button battery cr2032 in daily life. The main advantage is stable voltage and low price, but it also has problems such as low specific energy, short service life and frequent daily maintenance. In China, lead-acid batteries are widely used in low-speed electric vehicles in China. In addition to the advantages mentioned above, the price of this button battery cr2032 is also lower than that of other batteries. Lead-acid batteries are available in 2V, 4V, 6V, 8V, 12V and 24V series, with capacities ranging from 200mAh to 3000mAh. So let's calculate the discharge time of lead-acid batteries. Here is a formula that can be used to roughly calculate: rated capacity × discharge capacity rate × [1 + temperature coefficient × (ambient temperature - 25)] / discharge current = discharge time. Although lead-acid batteries are cheap, their button battery cr2032 life is relatively low. Therefore, it is not very appropriate for electric vehicles to be powered entirely by this type of button battery cr2032. Lithium iron phosphate batteries are lithium-ion secondary batteries, which are mainly used as power batteries. Moreover, they have a high discharge efficiency. The charge and discharge efficiency under rate discharge conditions can reach more than 90%, while that of lead-acid batteries is about 80%. Among batteries, lithium iron phosphate batteries are also safer than other batteries. The theoretical life span can reach 7 to 8 years, and the actual service life is about 3 to 5 years. The performance-price ratio is theoretically more than 4 times that of lead-acid batteries. Let's talk about its disadvantages. The price of lithium iron phosphate button battery cr2032 is higher than other types of batteries. In addition, the button battery cr2032 capacity is small, the driving range is short, and it can't be reused after being scrapped. There is no alternative price. In summary, the application of lithium iron phosphate button battery cr2032 in electric vehicles will increase the overall cost, and the button battery cr2032 cannot be recycled, which will cause waste and consumption of resources. The button battery cr2032 of TESLA electric vehicle adopts the NCA series (nickel cobalt aluminum system) 18650 lithium cobalt oxide button battery cr2032 provided by Panasonic, and the capacity of a single button battery cr2032 is 3100 mAh. TESLA adopts the strategy of button battery cr2032 pack. The button battery cr2032 unit of 85kWh MODELS uses a total of 8142 18650 lithium batteries. Engineers first distribute these batteries one by one in bricks and sheets to form a whole button battery cr2032 pack, which is located on the bottom plate of the vehicle body. Cobalt oxide lithium button battery cr2032 has a stable structure, high capacity ratio, outstanding comprehensive performance, but its safety is poor and the cost is very high. It is mainly used for small and medium-sized batteries with a nominal voltage of 3.7V. When TESLA puts such batteries together, safety becomes a very important issue. TESLA engineers distribute the safety devices in the button battery cr2032 pack to each 18650 cobalt oxide lithium button battery cr2032. Each 18650 cobalt oxide lithium button battery cr2032 is equipped with a fuse at both ends. When the button battery cr2032 overheats or the current is too large, the fuse will be cut off to prevent the entire button battery cr2032 pack from being affected by an abnormal situation (overheating or excessive current) in a certain button battery cr2032. So, from this point of view, although the cobalt oxide lithium button battery cr2032 itself has shortcomings, the cobalt oxide button battery cr2032 pack has a higher range and total button battery cr2032 capacity than other batteries. If the safety of the cobalt oxide lithium button battery cr2032 is improved a little bit, then its promotion in electric vehicles can not only be on Tesla. button battery cr2032 technology is still constantly changing. The era of ternary lithium batteries is gradually coming (lithium iron manganese phosphate button battery cr2032 is a kind of ternary lithium button battery cr2032). So, will the development of electric vehicles be restricted by batteries in the future? In my opinion, batteries will no longer be a constraint on the development of electric vehicles, and the core problem is gradually being resolved.
