Stanford can automatically power off battery OtterBox Note 4 Cases
January 12, Beijing time, Stanford University researchers have developed a new lithium-ion battery, it will automatically turn off when the battery to overheat, once these batteries installed in electronic equipment, such as skateboarding, laptop and cell phone, the device will no longer fire hazard. OtterBox N4
Lithium-ion batteries are widely used in various types of portable electronic devices, it is not only light, but you can also store large amounts of electricity, and can be easily replaced, battery easy to overheat when the downside is damaged. When the battery internal short circuit may cause a fire.
Developed battery Stanford professor
New battery developed at Stanford, researchers using polyethylene film, thin film embedded nickel powder, it will form nanometer processes. Researchers at the bulge covers Graphene conductive material, so current can flow from the surface through. When the temperature rises, the film expands, bulge when the temperature reaches 70 degrees Celsius will no longer connect with each other, circuit breaker, battery shut down. Power failure prevents the battery from overheating, then the battery will get cold, nickel raised will be connected together, continue to allow the battery to pass.
Stanford research team member, chemical engineering professor Bao Zhenan (Zhenan Bao) said: "we can adjust the high and low temperature, just change the embedded particle number is OK, can also use different types of polyethylene film to achieve this goal. "
Participation in the research of Chinese Professor Yi Cui at Stanford (Yi Cui), post-doctoral Chen Zheng (Zheng Chen). Yi Cui said: "compared with the previous method, we design a more reliable, faster, and reversible, it can ensure no decline in battery performance, and improved security. "
