The 'A Team' singer, who had chart success and rave reviews for his debut album +, said that the LP will be "more guitar-based".
Sheeran, 21, told the Daily Star: "I've already written a large part of the next album. It's going to have a bigger sound. It'll be more guitar-based."
He then joked: "I'll probably end up doing an Adele. I came out of a four-year relationship so maybe I'll write the whole album about the break-up and sell as many copies as she does."
Sheeran, who won two Brit Awards on Tuesday, also revealed where the prizes will sit in his house.
The 'Lego House' star added: "My Brits are going to go on the mantelpiece along with my Lego Millennium Falcon, which is there at the moment."
On the Brit Awards red carpet, Sheeran exclusively told Digital Spy that he is collaborating with two "really big" rappers.
