        basic introduction

        Lithium manganate battery refers to a battery that uses lithium manganate material for the positive electrode. The nominal voltage of the lithium manganate battery is 2.5~4.2v. The lithium manganate battery is widely used because of its low cost and good safety. 2018 is the inflection point of lithium batteries for electric bicycles. The demand for lithium batteries on electric bicycles will increase year by year. At present, the demand for lithium batteries is mainly concentrated on the use of lithium manganese oxide batteries, ternary batteries or two types of batteries. Some companies that are optimistic about lithium manganese oxide batteries say that it is a general trend that lithium batteries replace lead-acid batteries and nickel-metal hydride batteries in the electric bicycle market in the future. Lithium manganese oxide batteries are easy to take advantage of their multiple advantages in performance and price. Lithium acid batteries also have good expectations in other fields. After the new energy subsidy policy is completely withdrawn from the market, the cost advantage of lithium manganese oxide batteries will be greatly reflected. It may also have breakthroughs in the field of power tools and power vehicles. Has become one of the main forces in the field of new energy bus batteries.
