A cell in which liquid leakage or destruction may be prevented as the apparent energy density per unit volume of the cell is maintained. The cell uses, as a cathode active material, a compound of an olivinic crystal structure having the formula Li x Fe1-y M y PO4, where M is at least one selected from the group of Mn, Cr, Co, Cu, Ni, V, Mo, Ti, Zn, Al, Ga, Mg, B and Nb and 0.05 <= x <= 1.2 and 0 <= y <= 0.8. By adjusting the amount of the electrolyte solution, the amount of the void in the container is set so as to be not less than 0.14 cc and not more than 3.3 cc per 1 Ah of the cell capacity.
Pile dans laquelle les fuites ou la destruction du liquide peuvent être prévenues par maintien de l'énergie volumique apparente par unité volumique de la pile. La pile est dotée d'une cathode dont la matière active est un composé ayant une structure cristalline olivinique de formule Li x Fe1-y M y PO4, où M est au moins un des éléments suivants Mn, Cr, Co, Cu, Ni, V, Mo, Ti, Zn, Al, Ga, Mg, B et Nb, et 0,05 <= x <= 1,2 et 0 <= y <= 0,8. En ajustant la quantité de solution électrolytique, la quantité de vide dans la pile est établie de manière à ne pas se situer sous 0,14 cc, et à ne pas excéder 3,3 cc par 1 Ah de la capacité de la pile.
