DC screen with 12V24AH polymer lithium battery performance parametersIn the electric bicycle and small household car market, lead-acid batteries and lithium batteries are in applications because they have interoperable comparative advantages, lithium batteries have electrical properties and convenient advantages, while lead-acid batteries have safety and cost advantages. The performance of these two types of batteries in other applications is also true.

1: Nominal voltage different lead-acid battery monomer nominal voltages: 2.0V lithium electric monomer nominal voltage: 3.6V

2: Internal material, different lead-acid batteries, positive and negative, extremely grease, metal lead, electrolyte 正 正 正 负 极 为 为 为 为 负 负 负 正 正 正 正 正

3: Energy different lead-acid batteries 30WH / kg lithium battery 150WH / kg

4: Different lead-acid batteries: car start, electric car battery lithium battery: mobile phone, computer, power tool, now also used in electric vehicle batteries

5: Different lead-acid batteries of electrical characteristics cannot be high current, life life, short lithium battery can discharge high current, good life.

Everything about the two, the source is based on the properties of the material, the positive and negative electrode material of the lead-acid battery is the lead, metal lead, concentrated sulfuric acid; the lithium ion battery has four components: positive electrode (lithium cobaltate / manganese Sketium / lithium iron phosphate / triple), negative electrode graphite, diaphragm and electrolyte, thereby leading to different mainly:

1, the nominal voltage is different: the monomer lead-acid battery 2.0V, monomer lithium battery 3.6V;

2, the energy density is different: the lead-acid battery 30Wh / kg, lithium battery 110WH / kg;

3, the life expectancy is different, the lead-acid battery is 300-500 times, the lithium battery is more than a thousand times, from the two mainstream technology routes of lithium battery bicycles, the three-dimensional battery and the lithium iron phosphate battery are also relatively large. The three-dimensional lithium battery discharge life is 1000 times, and the life of the lithium iron phosphate can reach 2000 times;

4, charging method: lithium battery uses a limiting limit method, that is, a limit for a limit on current and voltage, and a more charging method of lead-acid batteries, and choosing to be: constant current charging method, constant Pressure charge method, stage and other flow charge and floating charge, can not be described.
