  • Publication number: 20240014471
    Abstract: A battery housing includes a first housing and a second housing. An accommodating space with an opening is defined by a bottom plate, two first side plates and two second side plates of the first housing. The second housing includes a body, and two first extending plates and two second extending plates arranged on a peripheral edge of the body. An avoiding region is formed on one second side plate. In a first direction, a width of the second extending plate corresponding to the second side plate provided with the avoiding region is smaller than or equal to a width of the avoiding region, and additionally, a width of the two first extending plates is greater than a width of the second extending plate. The second housing covers the opening of the first housing, and the two first extending plates and the two first side plates are fixedly connected.

  • Publication number: 20130090508
    Abstract: Disclosed is a method for preparing 1-octene in the presence of a catalyst system for ethylene oligomerization, which includes: premixing a part of ethylene gas as raw material with a solvent, mixing with the components a+b, c and d of the catalyst system, and then sending in a reactor; directly sending the rest of ethylene gas in the reactor; discharging the resultant liquid from the upper part of the reactor into an overflow channel; adding a catalysis stopping agent to the overflow channel; and then separating the resultant liquid. The advantages of the method are high selectivity of 1-octene and high catalytic activity.
