発明の名称 (英語) NEGATIVE ELECTRODE FOR POTASSIUM ION SECONDARY BATTERIES, NEGATIVE ELECTRODE FOR POTASSIUM ION CAPACITORS, POTASSIUM ION SECONDARY BATTERY, POTASSIUM ION CAPACITOR, AND BINDER FOR NEGATIVE ELECTRODES OF POTASSIUM ION SECONDARY BATTERIES OR NEGATIVE ELECTRODES OF POTASSIUM ION CAPACITORS
発明の概要(英語) Provided are: a potassium ion secondary battery which is not susceptible to deterioration of charge/discharge capacity even if charging and discharging are repeated, and which has a long service life as a secondary battery; a potassium ion capacitor; a negative electrode for the potassium ion secondary battery; and a negative electrode for the potassium ion capacitor. A negative electrode for potassium ion secondary batteries and a negative electrode for potassium ion capacitors, each of which contains a carbon material that is capable of absorbing and desorbing potassium and a binder that contains a polycarboxylic acid and/or a salt thereof. A potassium ion secondary battery which is provided with the negative electrode or the capacitor. A binder for negative electrodes of potassium ion secondary batteries or negative electrodes of potassium ion capacitors, which contains a polycarboxylic acid and/or a salt thereof.
特許請求の範囲(英語) [claim1]

[claim2]
2. The aforementioned carbon material contains the graphite, cathode for the kalium ion accumulator of claim 1 statement or cathode for the kalium ion capacitor.
[claim3]
3. The aforementioned poly- carboxylic acid and/or that salt, poly- acrylic acid, the poly- acrylic acid alkaline metal salt, includes 1 where it is chosen kinds at least from the carboxymethyl cellulose and the group which consists of the carboxymethyl cellulose alkaline metal salt, claim cathode for the kalium ion accumulator of 1 or 2 statements or cathode for the kalium ion capacitor.
[claim4]
4. Furthermore, the cathode collector which includes the aluminum is contained, either of the claim 1-3 cathode for the kalium ion accumulator of 1 section statements or cathode for the kalium ion capacitor.
[claim5]
5. Either of the claim 1-4 the kalium ion accumulator or the kalium ion capacitor which has the cathode of 1 section statements.
[claim6]
6. Poly- carboxylic acid and/or that salt is included, for kalium ion accumulator cathode or the binder for kalium ion capacitor cathode.
