Are lithium batteries really better than lead-acid batteries?

In 1860, Prantet of France invented a battery using lead as an electrode. The unique feature of this battery is that it can be recharged and can be used repeatedly, so it is called a 'lead-acid battery'. After a hundred years of development, lead-acid batteries are widely used in various industries and fields. So far, almost all cars are equipped with lead-acid batteries as a starting power source for cars. Electric motorcycles also widely use lead-acid batteries as the main power battery. There is no doubt about the cost-effectiveness of lead-acid batteries. However, with the continuous improvement of environmental protection standards, this heavy metal battery product has to choose to reduce the scope of use. Replaced by lithium batteries, lithium batteries have higher energy density and service life, especially lithium iron phosphate batteries, even if the battery life is 5-10 times that of lead-acid batteries, and the weight is lighter. The advantages of strong plasticity are gradually replacing lead-acid batteries. But are lithium batteries really better than lead-acid batteries? The answer is not absolutely one-sided. Comparison of the advantages and disadvantages of lead-acid batteries and lithium-ion batteries: 1) Sealed valve-regulated lead-acid batteries are not afraid of water and do not have high requirements for the use environment. They can work more stably even in harsh environments. However, lithium batteries have higher requirements for the use environment. 2) Lead-acid batteries are resistant to overcharging. Even in general overcharging, they will not have a great impact on the battery, while lithium-ion batteries cannot withstand the damage caused by overcharging at all. 3) Lead-acid batteries are generally solid. As long as the casing is not damaged or dropped, performance will not be affected. Lithium batteries are much weaker than lead-acid batteries. Some slight drops may cause abnormal operation of the entire battery pack. 4) Lead-acid batteries can be recycled and reused. The recycling and reuse of lead-acid batteries is very simple, and the cost is not high, and the recycled materials can be used for other purposes besides remaking batteries, while the recycling of lithium batteries is relatively more efficient. Complexity, high recycling costs, and single use of the main recycled materials. Comparison of the advantages and disadvantages of lithium batteries and lead-acid batteries: 1) Lithium batteries have greater energy density, and their weight is only one-third of that of lead-acid batteries. 2) Lithium batteries have a longer life, can achieve higher discharge efficiency than lead-acid batteries, and have stronger performance. 3) Lithium batteries have strong plasticity. Lead-acid batteries for special-purpose equipment cannot be realized with special-shaped batteries. Lithium batteries can be customized to provide power to the equipment. 4) Miniaturized lithium batteries can be used in devices such as mobile phones and Bluetooth headsets, but lead-acid batteries are not possible. Through the appeal comparison, it is not difficult to find that the lead-acid battery can be based on the market for a hundred years. Because its cost performance is irreplaceable, and it is supported by a mature industrial chain, it is still unsurpassed by lithium batteries in a short period of time. Moreover, lead-acid batteries have their own conditions and advantages that cannot be replaced by lithium batteries. The full range of lithium batteries still needs a long way to go. And with April 15th, the new national standard for electric bicycles ('electric bicycle safety technical specifications') was formally implemented. Lithium batteries on electric vehicles are basically confirmed. According to the new national standard, electric bicycles must have pedal riding ability, maximum design speed no more than 25km/h, vehicle weight (including battery) no more than 55kg, motor power no more than 400 watts, battery voltage no more than 48 volts, and Technical requirements such as anti-tampering, fireproofing, flame-retardant performance, and charger protection have also been added. The use of lithium batteries in electric vehicles is bound to be the mainstream and trend in the future. At present, the use of lithium batteries in electric vehicles is also a better choice. A lighter body can get a longer battery life, and may not accept the higher price of lithium batteries in a short period of time. However, as it goes deeper, the advantages of lithium batteries are gradually emerging. But this does not mean that lithium batteries are better than lead-acid batteries. Both have their own suitable industries and uses. As the market becomes more standardized and the current environmental standards, both lead-acid batteries and lithium batteries can be developed, and Better serve consumers in their respective fields.
