ELECTROCHEMICAL CELL HAVING COILED CORE |
摘要 |
An electrochemical storage cell having a coiled core is disclosed. The coiled core includes a cathode sheet, an anode sheet, and a separator sheet. An anode connector is connected with the anode sheet at a first end of the coiled core and a cathode connector is connected with the cathode sheet at a second, opposite end of the coiled core. The coiled core has a length Lcore and a width Wcore and each connector has a width Wconnector. The length of the coiled core Lcore, width of the coiled core Wcore, and width of each connector Wconnector have the relationship 0core-Wconnector)/Lcore<0.37. |
