A secondary battery includes: an electric cell layer including a stack structure sequentially including: a positive electrode layer, a separator layer, and a negative electrode layer having an electrolyte higher in conductivity than an electrolyte of at least one of the separator layer and the positive electrode layer.

Secondary battery and method of producing the secondary battery

A laminate cell comprises a power generating element formed by sequentially stacking positive electrode plates and negative electrode plates while interposing separators therebetween; a positive tab connected to the positive electrode plates through a plurality of positive leads; a negative tab connected to the negative electrode plates through a plurality of negative leads; and a cell package formed of a metal composite film, the cell package hermetically sealing the power generating element and an electrolyte. According to the laminate cell, the heat capacity of a portion of the positive tab, onto which a plurality of the positive leads are joined, and the heat capacity of a portion of the negative tab, onto which a plurality of the negative leads are joined, are made larger than that of other portions of the positive tab and the negative tab.

Laminate cell, assembled battery, battery module and electric vehicle

A laminate type battery comprises a substrate, a power generating element which has at least one single cell made by a positive electrode layer, an electrolyte layer and a negative electrode layer which are sandwiched by collecting layers from both sides thereof, and an electric circuit portion having electrode terminals which connect the collecting layers to an external device and circuitries which connect the collecting layers and the electrode terminals. In the battery, the power generating element and the electric circuit portion are formed by stacking a plurality of layers on the substrate, and each of the layers is configured such that the power generating element and the electric circuit portion are formed by stacking the layers.

Laminate type battery and method for manufacturing the same

An electrode for an all solid polymer battery comprises electrode active material particles which can absorb and release lithium ion through oxidation-reduction, a binder polymer, a polar polymer, and lithium salt. Herewith, the electrode for the all solid polymer battery, in which the cycle durability of the electrode is greatly improved, is provided.

Electrode with a phase-separated binder that includes a vinylidene fluoride binder polymer and a polyether polar polymer with a lithium salt

A laminate cell comprises a power generating element formed by sequentially stacking positive electrode plates and negative electrode plates while interposing separators therebetween; a cell package formed of a metal composite film, the cell package hermetically sealing the power generating element and an electrolyte; a positive tab connected to the positive electrode plates; and a negative tab connected to the negative electrode plates. According to the laminate cell, the power generating element and the cell package have approximately rectangular plane shapes, and the positive tab and the negative tab are drawn outward from end edges of long sides of the cell package.
