Technical parameters and energy density of lithium manganate battery

Technical parameters of lithium manganate battery Output voltage range: 2.5~4.2v Nominal capacity: 7500mAh Standard continuous discharge current: 0.2C Maximum continuous discharge current: 1C Working temperature: Charge: 0~45℃ Discharge: -20~60℃ Lead type: national standard line UL3302/26#, line length 50mm, white line is 10KNTC protection board parameters: (each parameter can be set according to customer products) overcharge protection voltage / each string 4.28±0.025V over discharge protection voltage 2.4±0.1V over Flow value: The application system of 2~4A lithium manganate battery still uses plug-in hybrid as an important application field. It cannot be ignored that there are 36 pure electric bus models with lithium manganate as an important application. The proportion of the installed models has reached 17%. BAIC New Energy, which uses lithium manganese oxide the most in pure electric bus models, followed by Xiamen Jinlong and CSR. In addition, Zhongtong, Yutong, Yangzijiang, Ankai, Shenlong, Yaxing, etc. have all started in pure electric bus models. Application of lithium manganate. Energy Density of Lithium Manganese Ion Battery Lithium manganate is based on EMD (a raw material, used as a special material for mercury-free alkaline manganese batteries) and lithium carbonate (also a raw material), with corresponding additives, through mixing, sintering, etc. Steps are produced. In addition to lithium manganese oxide, lithium cobalt oxide and ternary lithium ion battery positive electrodes are also spinel structures, but the spinel structure of lithium manganese oxide is very distinctive compared with its two counterparts, namely: advantages and disadvantages Both are very prominent. Its advantages are: low temperature resistance, good rate performance, and easy preparation. The disadvantages are: the material itself is unstable and needs to be mixed with other materials, poor high temperature performance, poor cycle performance, and fast attenuation. These shortcomings of lithium manganate come from the characteristics of manganese. However, due to the widespread existence of manganese, it has obvious cost advantages. Because lithium manganate materials have such distinctive characteristics, people can use their advantages and suppress their shortcomings to make lithium manganate batteries used in different fields, which are usually referred to as two applications of type A and type B. Class A refers to the power lithium battery, focusing on safety and cycle performance, and the requirement is that the reversible capacity is 100~115mAh/g, and it can maintain 80% of the capacity after 500 cycles. Class B is mainly used in consumer electronics (mobile phones). It is characterized by high capacity. The general requirement is that the reversible capacity is 120mAh/g, but the cycle performance only requires that the capacity be maintained at 60% after 300 to 500 times.
