COIN TYPE LITHIUM SECONDARY BATTERY AND IoT DEVICE |
| abstract |
Provided is a coin type lithium secondary battery for which battery resistance is not susceptible to rising even when usage conditions for an IoT device (constant voltage charge or pulse charge/discharge) are operated repeatedly. This coin type lithium secondary battery comprises: a positive electrode plate comprising a lithium composite oxide sintered plate; a negative electrode plate comprising a titanium-containing sintered plate; a separator interposed between the positive electrode plate and the negative electrode plate; a positive electrode current collector provided non-adhesively on a surface of the positive electrode plate on the side separated from the separator; a negative electrode current collector provided on a surface of the negative electrode plate on the side separated from the separator; an electrolyte; and an exterior body comprising a positive electrode can, a negative electrode can, and a gasket, wherein the positive electrode current collector further comprises a positive electrode side carbon layer on the surface of the positive electrode plate side, and contact between the positive electrode current collector and the positive electrode plate via the positive electrode side carbon layer is held not by adhesion between the positive electrode current collector and the positive electrode plate, but rather by pressure by crimping of the positive electrode can and the negative electrode can. |
