Mie Prefecture, Japan prototype out of sheet can be bent all-solid lithium-polymer rechargeable battery
Mie Prefecture Industrial Support Center announced the trial out of the printing process using only the "flaky all-solid lithium-polymer rechargeable battery." According to reports, the product is safe, ultra-thin, flexible, large area and so on. Physical products will be in March 2010 3 to 5 days at the Tokyo Big Sight International Convention and Exhibition Center at the show "the first session of the International Battery Exhibition" on display.
The lithium-ion rechargeable battery cathode layer, electrolyte layer and cathode layer of all the technical production by volume of the volume. Is not used between layers of membrane. Using LiFePO4 as cathode and carbon compounds such as electrolytes used by the cross-linked polyethylene oxide polymer material composition of the film, the negative electrode uses Li4Ti5O12 with graphite and silicon compounds. The polymer electrolyte material is in solid form rather than the gel (Gel), as did not use a flammable organic electrolytes, security is high.
The cell size is A6 size, thickness of 450μm. The initial capacity of 45mAh, the capacity of 1 / 2 to discharge when the voltage is 1.8V. Discharge frequency can be within 0.02C ~ 1.0C to make changes 6Y270,75UYF.
The original all-solid lithium-polymer rechargeable batteries there's topic is at room temperature under low temperature environment can not be driven, the battery can be 0 ~ +25 ℃ temperature use. Charge-discharge cycle over 100 times, is currently being implemented evaluation experiments.
New battery development center Mie University, Mie Prefecture Industrial Research Institute, Suzuka Industrial College, Jinsheng Industrial (Kinseimatec), KUREHA ELASTOMER, Shin-Kobe Electric, Toppan Printing and Ming-Cheng chemical industries involved in the battery development.
