In 1860, Prandtl of France invented a battery with lead as the electrode. The unique feature of this battery is that it can be recharged and used repeatedly, so it is called "lead-acid battery". After a century of development, lead-acid batteries are widely used in various industries and fields, and so far, almost all cars are equipped with lead-acid batteries as car starting power. Electric motorcycles also widely use lead-acid batteries as the main power battery. The cost performance of lead-acid batteries is undeniable, but with the continuous improvement of environmental standards, this heavy metal battery product has to choose to reduce the scope of use. Replaced by lithium batteries, lithium batteries have a higher energy density and service life, especially lithium iron phosphate, even after the group life is still 5-10 times that of lead-acid batteries, and lighter weight. Plasticity and other advantages are gradually replacing lead-acid batteries. But lithium batteries are really better than lead-acid batteries? The answer is not absolute lopsided.
Advantages and disadvantages of lead-acid batteries compared with lithium-ion batteries.
(1) sealed valve-controlled lead-acid batteries are not afraid of water, the requirements of the use of the environment is not high, even in a harsh environment, can work more stable. The lithium battery has higher requirements for the use environment.
(2) lead-acid batteries are resistant to overcharging, even if there is a general overcharge situation, the battery will not cause great impact, while lithium-ion batteries are completely unable to withstand the damage caused by overcharging.
(3) lead-acid batteries are generally more solid, as long as the shell does not appear broken drop, basically will not have an impact on the performance of lithium batteries are much weaker than lead-acid batteries. Some minor drops may lead to abnormal work of the whole battery.
(4) Lead-acid batteries can be recycled and reused, the recycling of lead-acid batteries is very simple, and the cost is not high, and the recycled materials can be used for other purposes besides being made into batteries again, while the recycling of lithium batteries is relatively more complicated, the recycling cost is high, and the main materials recovered are used for a single purpose.
The advantages and disadvantages of lithium batteries compared with lead-acid batteries.
(1) Lithium batteries have greater energy density and weigh only one-third of lead-acid batteries.
(2) The life of lithium batteries is longer and can achieve higher discharge efficiency and stronger performance than lead-acid batteries.
(3) lithium batteries are malleable, some special-purpose equipment shaped battery lead-acid batteries can not be achieved, while lithium batteries can be customized shaped battery to provide power to the device.
(4) miniaturization of lithium batteries can be used for cell phones, Bluetooth headsets and other devices, lead-acid batteries can not be achieved.
Through the appeal of comparison is not difficult to find, lead-acid batteries can be based on the market for a century due to its own cost performance is irreplaceable, and there is a mature industrial chain as a support, which is lithium batteries in a short period of time, such as any is unable to surpass, and lead-acid batteries have their own conditions and advantages can not be replaced by lithium batteries, the full range of lithium batteries still need a long way to go.
And with the April 15 electric bicycle new national standard ("electric bicycle safety technical specifications") officially implemented. The lithium battery on electric bicycles is basically determined. According to the new national standard, electric bicycles must have the ability to pedal riding, the maximum design speed does not exceed 25km/h, the weight of the vehicle (including the battery) does not exceed 55kg, motor power does not exceed 400 watts, battery voltage does not exceed 48 volts, in addition to increased anti-tampering, fire, flame retardant performance, charger protection and other technical requirements. The use of lithium batteries for electric vehicles will be the mainstream and trend in the future.
For now, the use of lithium batteries for electric vehicles is also a better choice. Lighter body can get farther range, may be in a short period of time the consumer in will not be able to accept the higher price of lithium batteries, but with the depth, the advantages of lithium batteries are gradually emerge. But this does not mean that lithium batteries are better than lead-acid batteries, both have their own suitable industries and uses, with the market more standardized and the current environmental standards, lead-acid batteries and lithium batteries can be developed and better serve consumers in their respective fields.
