Source: 2020 - 03 - 29 blessed hits: time why Honda's accord hybrid used in lithium batteries rather than nimh? Advantages of nimh battery: Toyota hybrid power system in the research, still very expensive lithium-ion batteries, nickel metal hydride batteries are cheaper, nickel metal hydride battery under the condition of shallow charge-discharge service life is long, nickel metal hydride batteries safer than lithium battery. In addition, the nimh batteries in the process of production more environmentally friendly advantages: lithium battery energy density is bigger, to make the same volume and weight of the battery capacity is small, the increased use of cars space to achieve energy saving and low weight, and protocol hybrid cars as the main source of power, speed is less than 80, motor driven by a motor power, high demand instant charging and discharging, lithium battery is more qualified for this job, the defect is that Honda hybrid system cost is higher, the late maintenance more expensive lithium-ion battery according to the shape can be divided into laminated type, button type, cylindrical, etc. , battery capacity and the standard is different, its size is also different. For any type of battery, the positive and negative of fold, this is the key to manufacturing lithium ion battery, is used in a larger area. From the electrodes to the battery, the manufacturing process due to the shape of the battery. However, the positive and negative active material, such as conductive agent, binder paste allocation methods, and the making craft of electrodes ( The upstream process) , are all the same.
