The performance of lithium battery and lead acid batteries

Source: 2020 - 04 - 19 he hits: times of lithium battery and lead acid batteries differ in that the battery voltage is different, different weight of battery, battery capacity, battery charging and discharging cycle life is different, the price of the battery is different, one is a lead-acid battery is not environmental protection, environmental pollution, and environmental protection batteries, lithium ion battery and its application field is different also, lithium batteries can be used in digital products, storage products, power products, while lead-acid batteries can only be used for some electric power and energy storage products, let's take a look at what is the difference between the lithium battery and lead acid batteries. Lithium battery and lead acid batteries, lithium batteries, and 1 environmental difference of lead-acid battery: the lithium battery belong to environmental protection battery, the national support can be seen on the development of new energy strategy, support the development of new energy electric vehicles lithium battery is helpful to reduce the amount of pollution in addition to pollution, and when the lead-acid battery manufacturer after close lead-acid battery factory, a regulated lead-acid battery has even started to reduce pollution in this area, and the power lithium ion battery and new energy subsidies. 2, charge: the difference between a normal charging 4. 2 V lithium-ion batteries, lithium ion battery is a rechargeable lithium ion batteries, lead-acid battery can charge 2. 4 V, general water or maintenance-free lead-acid batteries, lead-acid battery VRLA is mainly composed of lead and its oxide is a kind of electrode, electrolyte battery acid solution, lead-acid battery charging status, the main components are all lead sulfate is negative, the lithium cathode for lithium battery charging status. Lithium battery pack 3. Different voltage: the nominal voltage of lithium-ion batteries is 3. 7 v, can be in any series parallel combination into different voltage of lithium battery pack; The nominal voltage of the single gate lead-acid storage battery is 2. 0 v, in six commonly used in the application of the single gate in series with the lead-acid battery constitute the nominal 12 v lead-acid battery, including 24 v lead-acid battery. 4. High energy density is different: the lithium battery energy density, lithium battery now than can achieve 240 wh/kg. The lead-acid battery energy density is commonly 40 wh/KG. Because of the lead-acid battery very mature, the energy density of the lead-acid. By 2020, lead-acid battery energy density is expected to reach 45 wh/KG. 5, different weight: if will be in accordance with the 2200 mah lithium-ion batteries. 7 v18650 lithium battery to calculate the weight, it generally is about 47 g, and the same 2. 0 v lead-acid battery weight is about 2. 0 kg, that is to say, lead-acid battery weight is much heavier than lithium battery weight. 6, different discharge: lithium ion, lithium battery discharge lithium battery anode, lithium battery cathode, lithium ion moves between the anode and cathode, the electrode itself does not change the lithium ion battery anode graphite crystal, lithium oxide cathode, usually the high discharge energy, when the design can also support the high rate discharge, 30 c discharge under the condition of lead-acid batteries, the main composition of the anode is lead dioxide, a major component of the cathode is lead. Lead-acid different in lithium battery 7, cycle life: battery cycle life is what we call durability, more durable than lead-acid batteries, lithium-ion batteries because lithium battery charge and discharge more than 500 times, and there is no memory function, general lithium battery life between 4 to 5 years; And lead-acid batteries are usually in a deep deep discharge, 400 times have memory, lead-acid battery life of about two years, if the use of lead-acid battery maintenance is free, it is necessary to pay attention to the cell loss less water, generally do not need to add distilled water. 8. Different prices: lead-acid battery than lithium battery is relatively cheap. In 12 v10ah batteries, for example. Lithium battery and lead acid batteries variance analysis, found that more and more people begin to replace the lead-acid battery and lithium battery, namely before some customers like to use lead-acid batteries are now beginning to slowly accept lithium battery, which promote the environment, in fact, sometimes the lead-acid battery and lithium battery can imagine he closed his eyes and saw you accept, or not to take a look at the following lithium battery and lead acid battery is the difference between the advantages and disadvantages of contrast, hope to inspire.
