Provided is a technique of achieving a longer-life lithium ion secondary battery. The lithium ion secondary battery includes a cathode including a cathode active material containing Mn, an anode including an anode active material containing graphite and non-aqueous electrolytic solution including electrolyte, and LiBFand LiPFare allowed to coexist in the non-aqueous electrolytic solution. Especially preferably LiPFis contained more than LiBFin the electrolytic solution. Preferably the electrolytic solution further includes iodide salt. As a result, an oxide of phosphor and boron is deposited on the cathode, thus preventing elution of Mn included in the cathode. The amount of these electrolytes is preferably in the decreasing order of phosphor, boron and then iodine.

Lithium-ion rechargeable battery

A nonaqueous electrolyte and a lithium-ion secondary battery using the same, wherein a mixture of a cyclic carbonate, a chain carbonate, a first phosphoric acid ester wherein bonding between carbons is a single bond, and a second phosphoric acid ester wherein bonding between carbons contains a double bond is used as the nonaqueous electrolyte. It is desirable that the first phosphoric acid ester is a trimethyl phosphate. In addition, it is desirable that the second phosphoric acid ester is a dimethylisopropenyl phosphate.

Nonaqueous electrolyte and lithium-ion secondary battery using thereof

A non-aqueous electrolyte and a lithium secondary battery using the same are provided, which satisfy both flame retardancy and charge-discharge cycle characteristics, and attain a longer lifetime of the battery. A mixture of a chain carbonate, vinylene carbonate, a fluorinated cyclic carbonate and a phosphate ester is used as the non-aqueous electrolyte. It is desirable that the phosphate ester includes trimethyl phosphate and a fluorinated phosphate ester. Further, it is desirable that ethylene carbonate is further contained.

Handheld information terminal device

A conductive fixed static elimination member is provided in a before-magnetic head travel portion which guides a magnetic card to a magnetic card reader unit provided with a magnetic head, such that a protuberance portion thereof protrudes into a card travel groove through an opening formed in one of side walls, and has a conductive cleaning pad affixed to a surface thereof. The magnetic card inserted in the before-magnetic head travel portion is cleaned by the cleaning pad, and if the magnetic card has static electricity, it is possible to eliminate the static electricity by discharging the static electricity to the ground via the cleaning pad having conductivity, the fixed static elimination member, and a magnetic card reader fixing bracket.

Magnetic card reader

A magnetic head is held by a side wall through a head fixing fitting so as to freely advance into and retreat from a card sliding groove. First and second head urging levers are swingably supported through a pin. In a standby state, the magnetic head is away from the card travel groove, and card engaging sections of the first and second head urging levers are staying in the card travel groove. When a magnetic card slides in a card sliding direction, the magnetic card makes contact with a card contact section to push the card contact section away from the card travel groove. This causes the first head urging lever to push out the magnetic head into the card travel groove so that the magnetic head makes contact with the magnetic card.

A solid polymer electrolyte is made up of a polymer compound having a hydrocarbon aromatic group in the backbone thereof and including a side chain expressed by FORMULA 1: wherein 'n' is 1, 2, 3, 4, 5, or 6. The solid polymer electrolyte may be incorporated into a membrane and may be used in a solution for covering an electrode catalyst.
