Abstract

This battery is provided with: electrodes including a positive electrode and a negative electrode; and a particle-containing insulating portion provided between the positive electrode and negative electrode and including particles and a resin, the particles being made of a substance that undergoes a dehydration endothermic reaction, and having a flat shape with an aspect ratio of 2 / 1 or greater.

Description

technical field [0001] The present invention relates to a battery, an electrolyte, a battery pack, an electronic device, an electric vehicle, an electric power storage device, and an electric power system. Background technique [0002] In recent years, there are various types of portable electronic devices, and their size and weight are reduced. In order to make a portable electronic device smaller and lighter, a battery used as a power source of the portable electronic device also needs to be smaller, and an accommodation space within the portable electronic device needs to be efficiently used. [0003] Lithium-ion secondary batteries are well known to have high energy density and thus are best suited to meet such demands. For example, a lithium ion secondary battery having a laminated film as its external member is commercialized because such a battery is manufactured to have light weight, high energy density, and a very thin shape. [0004] A lithium ion secondary batte...
