    High-energy density lithium batteries are half the weight of nickel-cadmium or nickel-hydrogen batteries of the same capacity, and are 20-30% of the volume of nickel-cadmium and 35-50% of nickel-hydrogen. High voltage The working voltage of a single lithium battery is 3.7V (average), which is equivalent to three nickel-cadmium or nickel-metal hydride batteries connected in series. Pollution-free lithium batteries do not contain harmful metal substances such as cadmium, lead, and mercury. No metal lithium Lithium batteries do not contain metal lithium, so they are not subject to restrictions on the prohibition of carrying lithium batteries on passenger aircraft. High cycle life Under normal conditions, the charge and discharge cycles of lithium batteries can exceed 500 times, and lithium iron phosphate can reach 2,000 times. No memory effect The memory effect refers to the phenomenon that the capacity of the nickel-cadmium battery decreases during the charging and discharging cycle. Lithium batteries do not have this effect. Fast charging uses a constant current and constant voltage charger with a rated voltage of 4.2V, which can fully charge the lithium battery within 1.5-2.5 hours; and the newly developed lithium iron phosphorus battery can be fully charged within 35 minutes. If you are looking for a suitable lithium battery charger, then the professional charger manufacturer from summit charger can provide you with an efficient, convenient and long service life lithium battery charger, let us know more about lithium battery chargers.

    In 1970, M.S. Whittingham of Exxon used titanium sulfide as the positive electrode material and metallic lithium as the negative electrode material to make the first lithium battery.

    In 1982 R.R. Agarwal and J.R. Selman of the Illinois Institute of Technology discovered that lithium ions have the property of intercalating graphite, a process that is fast and reversible.

    In 1983, M. Thackeray, J. Goodenough and others found that manganese spinel is an excellent cathode material, with low price, stability and excellent conductivity and lithium conductivity. Its decomposition temperature is high, and its oxidizing property is much lower than that of lithium cobalt oxide. Even if there is a short circuit or overcharge, it can avoid the danger of burning and explosion.

    In 1989, A.Manthiram and J.Goodenough found that a positive electrode with a polymeric anion would produce a higher voltage.

    In 1992, Sony Corporation of Japan invented a lithium battery with a carbon material as the negative electrode and a lithium-containing compound as the positive electrode. During the charging and discharging process, there is no metal lithium, only lithium ions. This is a lithium ion battery.

    Throughout the history of battery development, we can see three characteristics of the current world battery industry development. One is the rapid development of green and environmentally friendly batteries, including lithium-ion batteries, nickel-hydrogen batteries, etc.; the second is the transformation of primary batteries into batteries, which is in line with sustainable development. Development strategy; third, the battery is further developed in the direction of small, light and thin. Therefore, the technology of battery chargers has also made greater technological breakthroughs with the continuous development of batteries, which requires the chargers to be smaller in size, portable, waterproof, shockproof, dustproof and other requirements. Summit power is a company specializing in charging. A high-tech enterprise integrating technology research, development, production and sales, we are committed to providing perfect chargers for various voltage lithium batteries. Let's explore more details together!

    Waterproof IP67.When the internal temperature of the charger exceeds 80 ℃, the charging current will reduce automatically. When it exceeds 85 ℃, the charger shutdown for protection. When the temperature drop, the charger automatically resumes to charge.when the output short circuit, the charger will automatically shut down the output. After troubleshooting, the battery can be reconnected to resume charging.when the battery is reverse connected, the internal circuit of the charger will automatically disconnect from the battery, without charging, without damaging the charger.If the input voltage is lower than 90V or higher than 264V, the charger will shut down protectively and automatically resume working with the voltage is normal again.Automatically shut down after full charge.

    Lithium battery chargers are widely used in energy storage power systems such as hydropower stations, thermal power stations, wind power stations, solar power stations, uninterruptible power supplies for post and telecommunications, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace, etc. field. and other fields. Therefore, the lithium battery charger can be applied to charge all lithium battery products.
