20100330402 | CAP ASSEMBLY WITH DESIRABLE SAFETY PERFORMANCE - A cap assembly with desirable safety performance for use in lithium ion batteries, includes an insulating gasket defining a through hole therein, a rupture plate positioned in the through hole, a vent plate defining an air hole electrically connected with the rupture plate, a current interrupt device disposed on the rupture plate, and an end cap defining an air exhaust hole assembled on the current interrupt device. The current interrupt device has an upper conductive plate electrically connected with the end cap, a lower conductive plate electrically connected with the rupture plate, and a fuse electrically connecting the upper conductive plate and the lower conductive plate. When the current intensity in the lithium ion battery exceeds a predetermined value, the fuse melts to cut off the current path. | 12-30-2010 |
20110136013 | Material for coating a positive electrode of a lithium-ion battery and a method for making the same - A method is disclosed for coating a positive active material of a lithium-ion battery. The method includes the step of dissolving at least one salt that contains a coating metal in a solvent to provide a solution, the step of dissolving a lithium-containing positive active material in the solution and adjusting the pH value of the solution to deposit M(OH) | 06-09-2011 |

20100330416 | ELECTROLYTE INJECTION AND EXPLOSION PROOF DEVICE FOR USE IN POWER BATTERIES - An electrolyte injection and explosion proof device for use in power batteries includes a cover defining an electrolyte injection hole, a rupture plate detachably disposed on the electrolyte injection hole, and an inner liner pressing the rupture plate on the electrolyte injection hole for sealing the same. The rupture plate detachably mounted on the electrolyte injection hole via pressing or clamping can be readily replaced, so that the power battery can be continuously used when the rupture plate is broken. Additionally, the explosion proof device is mounted on the electrolyte injection hole. The number of holes defined in the cover is reduced and the sealing performance of the power battery is remarkably improved. | 12-30-2010 |
