An eco friendly type often buys rechargeable batteries to reduce toxins, however what happens when you need a different size battery? They’re simply forced to buy more batteries. Well thanks to designers Pyeong Joo Goh, Jong Seung Choi and Ji Soo Hong all collaborated and designed AtoD rechargeable batteries. AtoD is a single nickel hydroxide battery core wrapped in memory foam which gives the battery to morph into any battery size between AAA to D.

The concept does have its issues. One is the issue that the AtoD battery may not even have enough juice to keep a larger product running. Now the issue has been looked over and at this moment in time it seems as though AtoD battery’s may be used simply as a short term replacement. Another problem is the issue of heat when in contact with the memory foam coated battery. Despite a few questions, AtoD battery proves to be an intriguing concept that definitely has huge potential. It’ll be interesting to see how the concept improves as technology grows.
