Electrolytes for Low Flammable Accumulators

Original language description

The development of modern technologies in area of portable electronic devices and electromobility made a main problem rising, the safety of accumulator. Thanks the low weigh, high energy density, zero memory effect the lithium ion batteries are the most common batteries used in such devices. The main components of lithium ion batteries a part of packaging and regulation circuits are cathode and anode materials, electrolyte and separation. As positive materials are used oxides like LiCoO2 or LiFePO4. For negative electrode materials are used different modification of carbon (natural, synthetic). The electrolyte is based on mixture of organic solvents like ethylene carbonate and dimethyl carbonate with lithium salt (LiPF6 at 1 mol l-1 concentrations). All these parts are flammable and that is why we need to deal with safety questions and search for new low flammable electrolytes. One of the possibilities are using of flame retardants. The flame retardants are used as additives into electrolytes. This paper shows the influence of flame retardant on the specific conductivity of electrolytes.
