There is provided an organic polymer porous body having a first cyclic structure equipped with a 6-membered ring (A) or a 5-membered ring having three bonds; a second cyclic structure equipped with a 6-membered ring (B) having two or three bonds; and a carbon-carbon triple bond that links the first cyclic structure to the second cyclic structure. At least one of the first cyclic structure and the second cyclic structure contains at least one nitrogen atom.

A negative electrode material capable of absorbing and desorbing lithium is comprised of a mixture of coke and graphite. The amount of graphite in the mixture is near to that which induces percolation transition. Preferably, the amount of graphite in the mixture is 2 to 37 wt % relative to the total amount of the coke and graphite. The coke may be prepared by heating raw coke from oil or coal at 500 to 900.degree. C. The coke may be 0.06 or more in the atomic ratio of hydrogen to carbon and 0.003 or more in the atomic ratio of oxygen to carbon. The graphite may be 0.5 .mu.m to 30 .mu.m in a mean particle size. Lithium secondary batteries comprising the negative electrodes have a large discharge capacity.

A front-end spoiler arrangement formed on an under cover of a vehicle has to sufficiently reduce not only front lift acting on front wheels, but also air drag. The front-end spoiler arrangement comprises a front part, a ridge, a step, and a rear part. The step defines a space at the rear part. The front part and the step prevents an increase of the air drag, and air whirls s produced in the space generate downward force.
