It can be done, but it isn't cheap.
glazed eyeball alert ...

LiNiCoO or lithium Nickel cobalt oxide is not lithium cobalt oxide. there's many different formulation of li-ion cells. what was available a decade ago has little relevance to chemistry available to day. Lithium technology is one of the fastest changing industries in the world. this is why loss of A123, America's only true lithium cell manufacture to foreign interests would be true long term blow. the technologies of tomorrow paid by US tax payer $$$ could be given away.

Other varieties of li-ion cells include: lithium cobalt oxide - LiCoO2 ; lithium manganese oxide - LiMn2O4 ; and lithium nickel oxide - LiNiO2. All these compounds refer to cathode material. electrolyte of a lithium-ion battery can vary. typically an aqueous fluidic solution of lithium salts, it can also be polymer based for easier shaping and safer puncture characteristics. anode of most cells are made of carbon.

each chemistry has it's own advantage and disadvantages of which LiFePO4 is the most stable.

LiFePO4 has advantages over other types of li-ion batteries. abundance of Iron available makes it relatively low cost. non-toxic making batteries safer to use as well as better for the environment, producing and recycling. with a longer life span in shelf life and cycle life. more stable than other chemistry's and far less likely to suffer from thermal runaway. LiCoO2 cells, can burst into flames if over charged and potentially release hazardous chemicals. Overcharging and overdischarging LiFePO4 cells will damage them, but generally without the explosive side effects. It can shorten cycle life or even result in deformation and a dead cell.
