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 parall...

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 cir...

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 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 o...

Including Apple products, including smart phones, Tablet by built-in lithium battery of the combustion and explosion for the same power-driven mobile power products are also full of wonder, consumers worried about power or it will become another source of this insecurity, and 18650 lithium-ion battery technologies that is one of its weaknesses.     As the world's most mature liquid lithium-ion technology battery types 18650 cylindrical lithium-ion battery or monomers form or in the form of batteries are widely used in mobile devices, in particular on tablets and Smartphones, but 18650 cell structure due to its characteristics, there are inevitably some shortcomings already reported above equipment explosion accident, are made 18650 Lithium-ion battery caused by short circuits: if used incorrectly or because the battery design problems of its own, will make lithium-ion batteries (Group), internal pressure is too large, in the case of pressure relief, the hard shell of ...
