리튬 이온 배터리와 NiMH 배터리 중 어느 것이 더 낫습니까? 리튬 이온 배터리와 니켈 수소 배터리의 차이점. Posted by batterymanufactory.com
Nickel-metal hydride batteries and lithium-ion batteries are widely used in the market. They are non-polluting and environmentally friendly batteries and are important areas for new energy development. So which is better, Ni-MH battery or Li-ion battery? The difference between lithium-ion batteries and nickel-metal hydride batteries Structurally, the positive electrode of the nickel-hydrogen battery is Ni(OH), the negative electrode is metal hydride, and the electrolyte is 6mol/L potassium hydroxide solution. The lithium ion battery is a negative electrode by inserting lithium ions into petroleum coke and graphite. The positive electrode material is usually LixCoO2, LixNiO2 or LixMnO4. The electrolyte composition is relatively complex, and LiPF6 + diethylene carbonate + dimethyl carbonate is mixed in proportion. Due to its mature technology and good safety, nickel-metal hydride batteries are an important choice for hybrid electric vehicle (HEV) batteries, but it is dif...
