Example Embodiment

[0021] The specific embodiments of the present invention are described below with reference to the drawings.

[0022] See Figure 1-Figure 7 The battery of the present invention has: an electrode immersed in the electrolyte, an ultrasonic element that applies an ultrasonic sound field to the electrochemical reaction zone and / or the electrode, wherein the ultrasonic element is fixedly connected to the electrode, that is, the ultrasonic element or the electrode directly fixed to the electrode The main body may be fixed in the support body, and then the support body is fixed on the electrode to indirectly realize a fixed connection with the electrode. The above-mentioned electrochemical reaction zone is the area where the electrode contacts the electrolyte. With the aid of the ultrasonic element, the present invention can apply an ultrasonic sound field to the battery, and the ultrasonic excitation mode is any one or a combination of positive electrode excitation, negative electrode...

Abstract

The invention provides a battery, which is provided with electrodes immersed into an electrolyte, wherein the contact area of the electrodes and the electrolyte is an electrochemical reaction area, each of the electrodes is provided with an anode (2) and a cathode (4), the battery is further provided with ultra-sound components (3, 5, and 6) exerting sound field of ultrasonic waves on the electrochemical reaction area and/ or the electrodes, wherein the ultra-sound components (3, 5, and 6) are fixedly connected with the electrodes. By using ultra-sound components for exerting sound field of ultrasonic waves on the electrodes, the power density that is times or tens of times higher than that of the current battery is provided, the energy density and the speed of charging and discharging are obviously improved, and the inner resistance of the battery is reduced and the power battery can be used in various occasions which require power batteries with high power densities and high energy densities, the power density of the current various battery techniques can be greatly increased to three times or even tens of times of the original power density.

Description

technical field [0001] The invention relates to a battery. Background technique [0002] With the era of high oil prices looming and the environmental changes of global warming, it is necessary to carry out major reforms on various vehicles and power stations that emit high carbon dioxide emissions in the era of fossil fuels. Electric drive, battery drive technology is currently the most promising technology to replace CO2-emitting vehicles of all types. However, the power density of the current main battery technologies is within 220W / kg (the latest reported lead-acid battery has been strengthened to 400-500W / kg), and the energy density is within 350Wh / kg (except for fuel cells, which have hydrogen storage efficiency and cost issues). Compared with traditional fossil fuels, this technological status quo makes batteries have large volume and mass number, vehicles have large volume and mass, and low speed, so they cannot directly compete. Contents of the invention [000...
