A lithium-ion secondary battery includes: a single cell that includes a first electrode, a separator stacked on the first electrode, and a second electrode stacked on the separator. The first electrode includes a porous body that includes at least one LLZ-based solid electrolyte of a lithium lanthanum zirconate or the lithium lanthanum zirconate doped with an atom other than a Li atom, a La atom, and a Zr atom, and has a pore, and an active material held in the pore. The separator has a relative density of 80% or more, and includes the at least one LLZ-based solid electrolyte of the lithium lanthanum zirconate or the lithium lanthanum zirconate doped with the atom other than the Li atom, the La atom, and the Zr atom, and at least one of a B atom, a P atom, or a Si atom.

Lithium-ion secondary battery and manufacturing method thereof

An electrochemical device has an electrochemical cell provided with an electrolyte having proton conductivity, an anode provided on one side of the electrolyte, and a cathode provided on the other side of the electrolyte. The electrochemical device is configured so that a solution containing water, an artificial synthetic resin, and an acid is supplied to the anode. The electrochemical device is configured so that an oxygen-containing gas is supplied to the cathode and connecting a load between the anode and the cathode. The electrochemical device is configured so that the inert gas is supplied to the cathode and connecting the voltage application unit between the anode and the cathode.

Electrochemical device

An exhaust purification system of an internal combustion enginecomprises: a filterarranged in an exhaust passage of the internal combustion engine and trapping particulate matter contained in exhaust gas, a catalystarranged in the exhaust passage at an upstream side from the filter in a direction of exhaust flow or supported on the filter, a fuel feed devicefeeding fuel to the catalyst, and a control deviceconfigured to control the feed of fuel by the fuel feed device. The control device is configured to feed fuel from the fuel feed device to the catalyst so as to burn off particulate matter trapped at the filter as processing for filter regeneration, and feed liquid state fuel from the fuel feed device to the catalyst after the processing for filter regeneration.

The exhaust purification system of an internal combustion enginecomprises: a catalystarranged in an exhaust passageof the internal combustion engine, a fuel feed devicefeeding fuel to the catalyst, and a control deviceconfigured to control the feed of fuel by the fuel feed device. The control device is configured to feed liquid state fuel from the fuel feed device to the catalyst when judging that a ratio of high viscosity components in particulate matter deposited on the catalyst is a predetermined value or less.
