There are at least two ways to interpret this question. The most likely case is that you are simply asking why batteries need to be inserted into a preexisting device, such as a portable radio, with their positive and negative contacts oriented in a particular way. The reason why batteries need to be oriented in a particular way is that most electronic devices require that the current flows through them in one specific direction to work properly. If it does not, the devices will not work, and likely will fail, perhaps in a spectacular fashion. (Current [electron flow] is from the negative to the positive terminals of the battery.) Devices that consist of a simple resistive element like an incandescent light bulb (not an LED), generally are not actually sensitive to the direction of current flow, and will work if the batteries are inserted backwards, although the mechanical contacts in the battery compartment may not touch the battery ends properly. If you are asking why batteries in general need to be placed in a particular place within an electronic circuit, then you need to take an entire course in electronics just to get started on the subject!
