A lithium secondary battery comprises a negative electrode capable of intercalating/deintercalating lithium ion, a positive electrode made of a lithium-containing metal oxide as an active positive material, and a nonaqueous electrolyte, and a polyvinylidene fluoride resin is disposed between said negative electrode and positive electrode so that the battery voltage doesn't rise beyond a predetermined value even when said battery is overcharged.
摘要:
The nonaqueous secondary battery according to the invention uses a separator 10 which is a composite resin film with a reinforcing material layer 11 integrally filled with polyvinylidene fluoride resin 12 or a separator 20 which is a composite resin film with a polyvinylidene fluoride resin layer 21 and a reinforcing material layer 22 stacked thereon. In this way, when the reinforcing material layer 11 is integrally filled with the polyvinylidene fluoride (PVdF) resin 12, or the reinforcing material layer 22 is stacked on the polyvinylidene fluoride (PVdF) resin layer 21, even if the polyvinylidene fluoride resin swells, its swelling is limited by the reinforcing material layer 11, 21 in the directions of width and length so that the separator 10 or 20 does not wrinkle.
摘要:
A nonaqueous secondary battery of the present invention comprises a polyvinylidene fluoride resin layer formed on either or both of the surface of the positive electrode and the negative electrode. This polyvinylidene fluoride resin layer exhibits excellent liquid retaining properties and thus can be formed on the surface of the electrodes to reduce the capacity drop during high temperature storage and hence improve the high temperature storage properties of the battery.
摘要:
A method of using a chip identification device is jointly performed by a chip mass-produced by a semiconductor manufacturing process, a first chip manufacturer making the chip, and a chip user assembling a product by using the chip. The method includes inputting a first published passcode, published by the first chip manufacturer, inputting a second published passcode published by a second chip manufacturer, inputting the first published passcode to the chip by the chip user, reading an aggregate of electronic output signals as a read code, sending the read code to the first chip manufacturer to compare the first output code and the read code. The chip is regarded as a counterfeit if the comparison is consistent.

The electronic appliance in the network are divided into the peripheral devices and stem servers managing registration information of the peripheral devices, wherein the stem servers serve as central control using software, and the peripheral devices are managed at device-level by having physical chip identification devices, thus the security of the whole network is efficiently reinforced.
摘要:
A network of electronic appliances includes a plurality of network units of electronic appliances. The network units include a first network unit and a plurality of second network units. The first network unit is connected to at least one of the second network units. Each of the network units includes a stem server and a plurality of peripheral devices connected to the stem server. The stem server includes at least one passcode and at least one list of a plurality of registration codes. Each list is associated to a respective passcode. Each registration code of one list associating to one passcode corresponds to a respective peripheral device. Each registration code is generated in response to a respective passcode using physical randomness of a respective peripheral device in correspondence to the passcode. An address of each identification cell is defined by several word lines and bit lines.
