This paper presents a new lithium ion battery by using a new fomulation ratio of material in a unit cell. The lithium ion battery used to a safety lamp decreased 1/4, weight to 1/7 by bulk than the existing lead accumulators, and made elevations such as carrying anger elevations and an efficiency of work etc. possible in this study. The life cycle and basic properties of the lithium ion unit-cell(φ 18×65(㎜)) is acquired by the charge-dischang experiment. The nominal voltage, nominal capacity and cycle life output of the lithium ion unit-cell is respectively 3.7V, 2.4Ah, and above 500cycle. Pack type lithium ion battery has the size of 29.5×73.5×115(㎜) and the weight of 300. In addition, the comparison confirming the effectiveness of the new lithium ion battery have been performed.

This paper presents a new lithium ion unit-cell and pack battery by using a new formulation ratio of material. The three types of formulation ratio for the unit-cell were used. The life cycle and basic properties of the lithium ion unit-cell(ψ18×65(㎜)) about one of them were acquired by the charge-discharge experiment. The nominal voltage, nominal capacity and cycle life output of the lithium ion unit-cell is respectively 3.7V, 2.4Ah, and above 500cycle. Pack type lithium ion battery has the size of 29.5×73.5×115(㎜) and the weight of 300g. As the results, the weight and bulk of lithium ion battery used to a safety lamp were decreased to 1/4 and 1/7. In addition, the comparison of the new lithium ion battery and lead storge battery for confirming the effectiveness of the new lithium ion battery have been performed.
