Ternary materials for lithium ion batteries

Ternary materials for lithium-ion batteries are lithium ion battery technology in the development of a new type of cathode materials for lithium-ion batteries, because of its comparative advantage, ternary lithium-ion battery materials showed broad prospects on the application in the market. Cathode material for lithium-ion battery from lithium to lithium cobalt oxide, manganese oxide, ternary material into three types (In addition to the dynamic type of lithium iron phosphate), So-called ternary materials for lithium-ion batteries is nickel, cobalt, and manganese salts as raw material, nickel and cobalt and manganese are three elements (ternary) battery cathode materials made of mixed in different proportions. The advantages of lithium cobalt oxide significantly, but the high price of Cobalt metal, has the advantages of lithium manganese oxide ratio performance, low cost, high temperature resistance and poor performance, ternary material for lithium-ion battery is integrated the ad

Lithium-ion batteries in parallel charging

Aims to increase the capacity of the lithium-ion batteries in parallel, therefore, parallel charging lithium-ion batteries compared with single lithium ion battery with different design features, mainly on the consistency in design and parallel battery charging current. Characteristics of lithium-ion batteries in parallel are: constant voltage, battery capacity addition, resistance decreases battery life extended. Parallel charging is the core content of the size and role of the current. According to the theory ， current is equal to the current of each branch and, therefore, have been combined as the battery n parallel li ion battery to achieve with the same single-cell charging efficiency, charging current for a number of current lithium-ion batteries, and Ohm's law: I=U/R under the formula, the design is reasonable. However, the parallel battery internal resistance will also change according to the parallel resistance formula, two parallel the total resistance of lithium-

Lithium battery explosion caused by the internal structural design

Panic caused by lithium ion battery cell phone explosion is always the thing after the terror, global brands including Dell, Apple has a similar embarrassment. This makes people think: lithium battery explosion was inevitable right? Is used in cell phones, laptops and other lithium-ion battery, called the lithium-ion battery is fulfilled by the movement of lithium ions between the positive and negative power supply and release of the device, it calls lithium ion can be attached when the shuttle between the positive and negative factors affecting the clean movement. In theory, this design is possible, but in practice, due to extremely powerful lithium-ion batteries are sensitive products, any abnormal conditions can cause problems with the battery. All lithium battery explosion is caused by a short circuit, causing short-circuiting has overcharge, discharge, over current, over heat, which is formed through the internal structure of lithium-ion batteries battery short circuit, the

Energy density of lithium-ion battery and its improvement ways

Lithium-ion battery is currently the main power supply for portable mobile device, ITC (Communications electronics) industry under the background of rapid development, which also shows a steady growth in demand. These last two years, Governments in the development of new energy sources and low-carbon economy policy is making capacity of the lithium ion battery market surge. However, with growth in demand for more powerful lithium-ion battery problem is: how to make the lithium-ion battery in the present volume releases more energy, or that release the same energy can make it smaller. This involves the development of lithium-ion batteries next can have much space. Also, we can transform this problem to how to improve the energy density of lithium batteries. Energy density of lithium-ion batteries is a numerically equal to the battery voltage and capacity of the product, but it's only a few, practical cathode material for lithium-ion battery energy density depends on the energy

Lead-acid batteries and lithium-ion battery charger will universal

Because lithium ion batteries replace lead-acid batteries in accelerating the process of, some people bought lead-acid batteries in electric cars and later replaced lithium battery electric vehicle, can not help but wonder: lead-acid battery charger can be used before on lithium batteries? In this regard, the relevant statistics, it is not feasible. Because of the lead-acid battery charger set for two-stage or three-stage charging mode, lithium-ion batteries and lead acid battery voltage levels are mismatched. There are many types of lithium-ion batteries, battery performance and battery protection board parameters may be different. So is not the same as lead-acid batteries lithium-ion batteries, a universal battery charger. In General, lithium ion battery manufacturer is equipped with a dedicated charger. In order to protect the battery, use a special charger. Is for lithium batteries you need to be aware of the following considerations: 1 In order to extend the battery life,
