I have a lenovo y50 laptop that I have bought recently and wanted to take it overseas. I am going to change the electricity from 120v at 60hz to 240v at 50hz. Do you think this will have some negative effects on my laptop's battery? And if so is it from the voltage or speed of the electricity?
-Thanks

You'll need a transformer for that. When I lived back in India, I got a NA 2DS and it wouldn't charge (more like overload since 240v would be going into the 120v device) until I bought a transformer.

input current is different than output current.
that's why transformers exist..
a change about the hertz and input voltage means nothing because it converts it for the device, the ac is changed to dc it goes from 240-100 to lets say 20 volts..
nowadays theese power adapters can be used in almost every country, the incompatibility is just the phisical connector.. this can be checked on it's printed specs

so basically, if you get the right adapter (or a good universal one) there will be no difference for your laptop
the battery charging is even controlled in a chip inside the computer itself actually...

And if so is it from the voltage or speed of the electricity?
frequency is not speed, electricity has always the same speed (not sure if there is a little variation i ain't physician)

Though they might be expected to know a fair bit about things a physician is a medical doctor. A physicist is the term you want, though they might in turn specialise in something very different. Similarly if you are interested in "speed" of electronics then look into inductance, circuit hazard and the Hall effect.

Anyway as others have said it quite different to what you were operating under.

The laptop takes a charger. This charger will convert AC into DC which has no frequency. Said charger may also be rated for 240V and 120V, and both frequencies (I could go into frequency and bog things down, however I won't beyond saying though 50Hz is less than 60Hz the 50Hz is actually harder to handle so while 50 can go to 60 just fine a few 60Hz devices may be troubled so do make sure the label says 50-60Hz).

You can buy devices to convert 240V to 120V, builders use them for all sorts of reasons but you might have to adapt one of those. Most however will not convert frequency in a useful way as that is a pain to do well.
For the most part though it will probably be easier to check if your devices have such options, buy replacement power supplies for the laptop (you are not going to want to lug around a converter with you too) if it does not do it by default.
