According to this report, when a battery is short-circuited externally, the internal temperature of the battery rises due to Joule heat caused by the short-circuit current (2), and the polypropylene nonwoven fabric used as the separator part softens and melts, causing an internal short circuit in which the positive and negative electrodes come into contact with each other. As a result, the internal temperature of the battery further rose and gas was generated due to the decomposition of the electrolyte, creating a risk of fire or explosion of the battery.

Figure 2 (A) shows the relationship between the current A11 and the measurement time. Figure 2 to+ shows the relationship between battery container temperature and measurement time.The curves in Figure 2 are based on the values of the battery with the higher current value and discharge of two identical batteries. be.

) The temperature of the battery container is approximately 105°C when the battery is Al, and approximately 90°C when the battery is fBl. Thereafter, as time passes, the current value hardly increases and the battery container temperature decreases.

輩は不１」能であった。At the point f (approximately 5 minutes after the short circuit for the two-pair battery to+), the double current value once decreases, and the double current value immediately increases, so the battery container temperature continues to rise. After about 7 minutes, the battery's internal pressure rose and the lid flew off, making further training impossible.

体となるため電流は流れなくなるのである。Let's consider the reason for this (2. In batteries (A, l (in the case of Bl)), a synthetic resin film with micropores used as a separator member at °C will cause a short circuit current (2). When the melting point of each film material (2Al'J-) is reached, the holes for micro-X are blocked by the melt, and the movement of ions is blocked.In other words, the separator member is not only electrically insulated but also Since it becomes an insulator that also blocks the movement of ions, current no longer flows.
その結果として電池温度もそれ以上上昇することなく発

化・溶融し電、池内短絡（１至ること（二なる。On the other hand, in battery (0) using polypropylene nonwoven fabric 7 as a separator member, when the oil temperature rises, the amount of ion transfer decreases because the polypropylene nonwoven fabric shrinks slightly by 14y. Either the current value decreases, or fundamentally the polypropylene nonwoven fabric has larger pores than Film C, so it is impossible to stop the movement of ions, and the current value increases again and the battery temperature increases accordingly. As the temperature rises, the polypropylene nonwoven fabric itself softens and melts, causing a short circuit within the battery (1).

Characteristics measured by short-circuiting each group of batteries, which are connected in series (two batteries each), after being acclimatized and held in a constant temperature oven at 70℃ (-). Figure 3 (a) shows the relationship between the current value and the 11th regular intercostal space, and Figure 6 (b) shows the relationship between the battery container temperature and the opening during measurement. The curve adopts the value of the battery with higher current value and temperature among two identical batteries.

Compared to +AI, as shown in Figure 3 (a), the current value hardly increases after being drastically reduced, and as shown in Figure 3 (b), the maximum battery temperature is lower and the characteristic C1 is superior. I understand that.

られる。The reason for this is thought to be C1 as follows. In other words, when we dismantled the short-circuit test characteristics, the polyethylene film was still film-like! However, the polypropylene film had a slight impact (2); It is presumed that ions move and current flows.Also, since polyethylene has a lower melting point, the rise in battery temperature can be suppressed.

業的価値は極めて大である。(f) Effects of the Invention As mentioned above, according to the non-aqueous electrolyte battery according to the present invention (second aspect), a synthetic resin film having micropores is used as a separator member, so even if an external short circuit is caused, Joule heat due to the short circuit current is generated. When the battery temperature rises, the fine pores of the film are blocked by the molten material, preventing the movement of ions, which prevents current from flowing. It can be completely improved and its industrial value is extremely large.
