lithium ion rechargeable battery trojan batteries - hybrid auto battery - the raw truth

In addition to gasoline engines, hybrid cars are also driven by electric motors that rely on batteries.Hybrid car batteries are produced in a manner related to conventional car batteries and have similar functions.The only difference is the larger volume of the hybrid car battery, thus being able to produce the expected huge power.
But compared to the batteries of pure electric vehicles, the batteries of hybrid cars are smaller because hybrid cars also use gasoline engines.In order to meet the needs of hybrid cars, their batteries have different internal structures and materials from traditional cars.The hybrid car battery may be a package that contains quite a few modules, each with a row of batteries.
At 2009 Toyota Prius, 201.
6-There are 28 modules in the V battery pack.Each module, usually packaged in stainless steel, contains 6 units, so the complete assembly has 168 units.The battery voltage of 650-is reversed to alternateAC motor.
When the package fails, it is likely that the module is defective and can be rebuilt by replacing the appropriate module.In any vehicle, the rechargeable battery is the ignition technology of the starting motor, lamp, engine and accessories and 12-V lead-The acid battery can provide the required power.Inside the hybrid car, different rechargeable batteries are used to run the motor driving the wheels, which means extra effective highVoltage batteries are expected.
Lead-The acid battery is heavy and cannot provide the expected power in a small package.For this reason, for practical purposes, most car manufacturers have turned to other forms of rechargeable batteries.Today, nickel-Most hybrid cars have metal hydrogen batteries installed.
More than 2 million people worldwide.
The electrode used in the NiMH battery is hydrogen-Absorption alloy of negative nickel hydroxide.Companies such as Toyota Prius, Honda Civic Hybrid and Honda Insight use NiMH batteries.A different battery will be a lithium ion battery with more power in a smaller package.
Lithium-ion batteries are composed of anode, cathode and electrolyte.The anode is carbon like graphite.The cathode is usually a layered oxide of lithium cobalt oxide, or a multi-anion such as lithium iron phosphate or magnesium-aluminum stone containing lithium manganese oxide.Electrolyte is actually a non-Water Organic carbonates containing lithium ion complexes.
The Honda hybrid will start using lithium batteries.While Toyota does have an interest in lithium mining, it insists on using NiMH (which costs about $4,000) instead of higher-priced lithium.But it is predicted that lithium may be the key to producing more economical hybrid cars in the future.
Less fuel consumption for hybrid cars, reducing pollutionAbandoned batteries have toxic effects on the environment, which will put another dilemma.All kinds of batteries are dangerous to the environment.Regarding the main source of the battery, although lithium is the least dangerous, lead is definitely the most dangerous.
Nickel is in the middle.
But if cobalt is used in lithium batteries then this will be a problem.Recycling Technology plays an important role in the environmental impact of these materials.Lead has mature recycling technology, but a large number of metric tons of lead enter the landfill every year.
Full recovery of Nickel remains a challenge and nickel is considered a possible carcinogenic substance.At present, of the 0.7 billion vehicles operating worldwide, millions of hybrid vehicles account for only a small portion.But with the increase in the production and use of hybrid cars, the impact of their batteries on the environment will be a problem that needs to be solved as soon as possible.
