ABSTRACT:
An improved non-aqueous electrolyte cell according to this invention includes a negative electrode which is a composite sintered body of a carbonaceous sintered material retained on an expanded metal mesh collector. The expanded metal mesh has a sheet thickness T, a mesh long width center distance LW, a mesh short width center distance SW, a mesh long width maximum opening, a; and a mesh short width maximum opening, b, all carefully specified to obey predetermined conditions in order to provide improved secondary cells having high energy density. The expanded metal mesh collector has a specified configuration to prevent carbon layer cracking and/or separation of the carbon layer, caused by shrinkage of the carbon layer on sintering or by expansion/shrinkage of the carbon layer during charging and discharging, to secure stable cell characteristics.
