Hitachi Maxell display laminated lithium-ion rechargeable battery
Recently, Hitachi Maxell rechargeable battery in the exhibition “International Battery Exhibition” exposed to the pyramid reference lithium (Li)-ion rechargeable Lithium “IMS65142235. New products are thicker dimensions 6.5 × width 142 × 235mm long, rated capacity of 10Ah. Rated voltage of 3.7 V, the termination voltage of 2.75 V,inspiron 700m battery , the maximum current of 30A. Hitachi Maxell, said the vision of new products for motorcycles and electric vehicles such as unmanned mobile with the power system and uninterruptible power supply backup, with improved cathode materials and structures, using high-resistant membrane heat to improve the safety of sex.
Using a cathode containing a high thermal stability of spinel type materials of manganese oxide. Membrane used in polyethylene products inorganic materials coated. Although the liquid electrolyte used but it is adapted for layered products. Polyethylene coating by improving the choice of inorganic materials, method and coating method which improves the heat resistance.
In addition to the products mentioned above, Hitachi Maxell is also developed presentation the importance of the energy density of the cylinder-type lithium-ion battery (Figure 2). Previously, the cylinder Society lithium-ion battery, the extraction of 15 ~ 20A current emphasis on export products of density. Although these lithium batteries for power tools, etc., but as products of electric bicycle, lack of capacity there, but also in the 0 ~ -20 ℃ low temperature discharge characteristics in the imperfect. The company said that by improving the material of cathode, anode and electrolyte materials, sony vgp-bsp13/s , the detailed composition and manufacturing process, in improving the energy density, it also improves the flow characteristics of environments at low temperature. Measurements of cell diameter of about 18.3 × 64.95mm length, weighs 45g, rated capacity of 2250mAh and a voltage rating of 3.7V, the termination voltage of 2.75 V, the maximum current 6A. Can estimate the weight of the energy density of about 185Wh/kg.
