Lithium energy, with its excellent characteristics, is widely used in mobile phones, video recorders and other small equipment. With the improvement of research and development technology, it has become the most mature technology used in high C-rate batteries such as drones, power tools, remote-controlled racing cars, etc.
Drone battery is powered mainly by lithium energyAt present, agricultural drones on the market mainly use lithium batteries as the main driving force. With the growth of the drone industry, coupled with the special application environment, the need for high C-rate and high energy density of lithium batteries, the industry prefers to call it a drone battery. Flight time is usually between 20 and 30 minutes. Due to technical differences in drones, most drones fly in about 45 minutes. Lithium batteries are batteries that contain lithium (including lithium metals, lithium alloys and lithium ions, lithium polymers) in electrochemical systems. Lithium batteries are rechargeable batteries that rely primarily on lithium ions to move between positive and negative poles. Lithium-ion batteries use embedded lithium compounds as electrode materials. Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium metal batteries are generally non-rechargeable and contain metal-state lithium. Lithium-ion batteries are free of lithium metal and can be recharged. Drone batteries use lithium-ion batteries.
Features of lithium energy as a agricultural drone battery materialLithium batteries, which are used as a battery material for drones, have many advantages. Lithium battery voltage platform is high, single cell nominal voltage of 3.7V, about equal to three nickel cadmium battery or Ni-MH battery series voltage, easy to form a battery power supply group. Grepow's single cell nominal voltage of 3.85V is a major breakthrough in battery technology. Compared to batteries, lithium batteries have high energy density. It has reached 460-600Wh/kg, about 6-7 times the size of lead-acid batteries. Tattu drone battery has an energy density of 260Wh/kg. Compared to lead-acid batteries, lithium batteries are lightweight and weigh about one-fifth of lead-acid products in the same volume. Lithium battery life is relatively long, the service life can reach more than 6 years, with lithium phosphate as a positive battery, the use of 1CDOD recharge, there are 1000 times can be used record. Grepow can produce drone batteries up to 500 cycles. With high power tolerance, the lithium-ion battery used in drones can reach 15-30C charge and discharge capacity, making it easy to fly with high C-rate power. Lithium battery self-discharge rate is low, no memory effect. Drone batteries can be used in conjunction with battery management systems. Lithium batteries are high-temperature and low-temperature adaptable, it can be used in the environment of minus 20 degrees Celsius to 60 degrees Celsius. After special process treatment, it can be used in the environment of minus 45 degrees Celsius. No matter from production, use and scrapping, lithium batteries do not contain or produce any toxic and harmful heavy metals such as lead, mercury, cadmium, etc.
Innovative technology for drone batteryDrone battery is also called smart flight battery. Although lithium batteries are good, things are not perfect. Grepow innovates in battery technology, perfecting lithium batteries with lithium polymer battery materials. Lithium polymer batteries are derivatives of lithium batteries. It can solve the problem that lithium batteries are poorly safe and prone to explosion. Lithium batteries of lithium cobalt acid materials cannot be discharged at high currents, but lithium polymer batteries can. Grepow has moved away from battery winding technology and adopted a new stacking technology. The advantages of stacking technology are small internal resistance, long life, high C-rate, high energy density. In terms of battery performance, stacking technology increases the battery's energy density by 5% under the same conditions, increases cycle life by 10% and reduces costs by 5%.
