Just bought Led flashlight flashlight, 5 hours charging 9 hours of electricity, and now there is no electricity, but the charger shows full power, but it is not bright, what is the matter?
LED lithium batteries are without memory. Once the battery is dry, the electricity is scrapped. Therefore, when the brightness of the flashlight is obviously lowered, the battery is charged and the power is switched off within one or two hours of the green light. For 9 hours, usually over charge or over release, it is recommended to replace the battery.
The cap of the lithium ion battery is provided with an explosion proof hole, and when the internal pressure is too large, the explosion-proof hole automatically opens and releases the pressure so as to prevent the explosion.
The anode material of lithium ion battery is cobalt oxide lithium, and the negative electrode is carbon. When charging the battery, lithium ion battery has generated cathode, lithium ion tea eng movement through the electrolyte to the cathode. As a negative electrode, the carbon presents a layered structure, and it has many micropores. The lithium ion that reaches the negative electrode is embedded into the micropores of the carbon layer, and the more lithium ions are embedded, the higher the charging capacity. Similarly, when the party discharges the battery (that is, we use the battery), the lithium ions embedded in the negative carbon layer emerge and move back to the positive electrode. The more lithium ion goes back to the positive electrode, the higher the discharge capacity. What we usually refer to as battery capacity is the discharge capacity.
The lithium ion battery has a spiral structure inside, and the anode and cathode are separated by a thin film of paper with many tiny holes. Lithium ion battery core is a new type of battery energy. It contains no metal lithium. In the process of charging and discharging, only lithium ion moves between positive and negative poles. Electrode and electrolyte do not participate in the reaction. The energy density of lithium ion core can reach 300Wh/L, and the weight, capacity and density can reach 125Wh/L. The reaction mechanism of lithium ion electric core is that with the charge and discharge, the lithium ion is inserted between the positive and negative poles, and it goes back and forth inside the electric core without the existence of metal lithium. Therefore, the lithium ion electric core is safer and more stable. The cathode of lithium ion battery is lithium cobalt, the positive collector is aluminium foil, the negative electrode is carbon, and the negative negative collector is copper foil. The electrolyte of lithium ion battery is an organism that dissolves LiPF6.
