The first phase, rich in ethylene carbonate (EC) or propylene carbonate (PC) liquid electrolyte of the binary. In 1996 the birth of the early lithium-ion battery, the electrolyte of EC or PC content was high, usually about 50%, then the use of anode materials for petroleum coke, and the embedded layer of the PC is not sensitive. At this point the poor performance of lithium-ion battery, capacity is also low, mainly used in the field of mobile phone batteries VGP BPS9 , VGP BPS9/B , VGP BPS9A , VGP BPS9A/B , VGP BPL9 , VGP BPS10 .
The second phase, rich in diethyl carbonate (DEC), dimethyl carbonate (DMC) and other components of the electrolyte low niandu . 1997 to 2004, in order to further improve the conductivity of the electrolyte to improve the type of electrolyte and graphite anode material compatibility, PC will not be using the basic, EC in the amount of control between 15% -35%. In order to improve the film-forming nature of the electrolyte, a new type of solvent such as methyl ethyl carbonate (EMC) with the EC, such as occur with the use of additives is also the beginning of this stage have emerged, and a small amount into the production phase of industrialization. At this time lithium-ion battery performance and capacity increased significantly longer Sony battery life, nickel-metal hydride, lead-acid battery market is fast alternative.
The third stage, diversified liquid electrolyte lithium-ion battery. In recent years, lithium-ion battery electrolyte developed very quickly, and optimize the program is also very much of the lithium salt electrolyte more than one, more complex solvent composition. In addition, the high temperature electrolyte, electrolyte temperature, electrolyte security, high-power battery electrolyte to occupy a prominent place to start. At the same time, the solvent is also a new and emerging applications. Therefore, to further improve battery performance, functionality, specialization more pronounced, thereby promoting the lithium-ion battery industry to enter the period of rapid development. At this point, the lithium-ion batteries continue to seize market share of traditional batteries toshiba PA3285U-1BRS , toshiba PA3399U-1BRS , but also continuously develop new applications, from digital products, energy storage batteries to toys, power tools, electric bikes and so on.
Lithium-ion Evo N610C battery electrolyte future direction of development will be: more secure, more stable, longer life lithium-ion electrolyte development and application (such as ionic liquids, but also the stability of the electrolyte salt, such as security), as well as to match, security better performance of the positive and negative laptop battery electrode material (such as lithium iron phosphate, etc.), so that the lithium-ion battery in the rapid spread of the field of electric vehicles.
