At the ARPA-E Energy Innovation Summit in Washington DC in February, start-ups and research organisations showed off the latest inventions in the multiple paths to cleaner energy.
PolyPlus Technology is developing lithium air and lithium water batteries that promise a big jump in the storage capacity of lithium ion batteries. The company has developed a material that will allow batteries to operate using the dissolved oxygen in water or the air, which its says is key to making energy-dense lithium air batteries viable.
The company's plan is to start making lithium water batteries for underwater uses, such as robots, in two years. Then it intends to make a lithium air battery one year later, and perhaps three to five years from now, a rechargeable lithium air battery.
