Abstract
An organic electrolytic solution secondary cell having a positive electrode, a negative electrode and an organic electrolytic solution, wherein a solvent of the organic electrolytic solution contains a triester of phosphoric acid, and the negative electrode contains a carbonaceous material, further, the carbonaceous material of the negative electrode has the specific surface condition, and carbon dioxide is dissolved in the organic electrolytic solution, whereby safety and shelf stability of the cell are increased, and also cell properties such as the closed circuit voltage, the retention (difference between the charge capacity and the discharge capacity), the discharge capacity and so on are improved.
