Que tipo de bateria é usada em carros híbridos?

Que tipo de bateria é usada nos carros híbridos hoje? Dióxido de cobalto, hidreto metálico de níquel ou íon de lítio são os tipos mais comuns.

Níquel-hidreto metálico

This battery is widely used in hybrid cars and cellular phones. Initially used in aerospace applications, it has a long life span and reasonable specific energy and power capabilities. While it is not as durable as lead-acid batteries, it is highly tolerant of abuse. However, a nickel-metal hydride battery is not a drop-in replacement for an alkaline battery. Its disadvantages include high self-discharge, heat, and limited storage capacity.

The lithium-ion and polymer batteries used in hybrid vehicles are largely safe. A two-year Toyota hybrid battery warranty will cover all battery parts for 120 months or 150,000 miles unless you’ve abused them. Nevertheless, lithium-ion and polymer batteries do have a similar lifespan and are not as reliable. In addition, a lithium-metal hydride battery is much heavier than a nickel-metal hydride battery, so they’re not as durable as Ni-MH batteries.

Although the nickel-metal hydride battery is less potent than lithium-ion batteries, it is also smaller and lighter than its lithium-ion counterpart. The size and weight of a battery pack constitute a significant disadvantage, which is why the bipolar version is a better option. Bipolar battery cells also enable 1.4 times more cells to be crammed into the same space.

Another significant difference between the two is the charging speed of lithium-ion batteries. Li-ion batteries are faster and can handle sudden power demands, while NiMH batteries have a longer charging time. However, both types of batteries are still widely used in hybrid cars and plug-in hybrids. A nickel-metal hydride battery is usually a better choice for hybrid cars unless equipped with a hybrid powertrain.

In recent years, many manufacturers of hybrid vehicles have switched to lithium-ion batteries. They reclaim this material as a valuable raw material for their new hybrid car motors. In the meantime, the manufacturer of the NiMH battery has begun supplying the carmaker with rare earth metals. This makes them the first to recycle nickel-metal hydride batteries. However, they are still far from the battery industry’s eventual 100 percent battery recycling goal.

A nickel-metal-hydride battery is also more environmentally friendly than lithium-ion batteries. The energy density of a NiMH battery is about 40 percent lower than that of a lithium-ion battery. A large battery in a hybrid vehicle can help with weight and power, but a battery that is too heavy will add weight. In the future, other types of batteries may be more popular in the automotive industry.

Some car companies are not producing enough hybrids. However, the demand for hybrid vehicles is growing. The battery is an integral part of the hybrid industry, and Toyota is trying to increase its hybrid sales. The company’s latest investment will result in a 200-gigawatt-hour battery supply. So, what is the best battery for hybrid vehicles?

Íon de lítio

The technology behind lithium-ion batteries is still evolving, but some benefits are apparent. The first benefit is their energy-to-weight ratio. The lower weight also translates into better handling, greater range, and twisty handling. Lithium-ion batteries are still a few years from becoming mainstream, but are proving themselves in hybrid car applications. Here are some reasons for their growing popularity.

A lithium-ion battery pack energizes the electric motors. It’s lighter than the lead-acid battery and lasts longer. The new technology promises even better performance. Lithium-ion batteries are also available in hybrid car models, including the new Honda CR-V. They are an essential part of hybrid cars and electric vehicles.

Another major advantage of lithium-ion battery technology is its fast rechargeability. Lithium-ion batteries can be recharged in a few hours, which is especially attractive for drivers who care about their environmental footprint. These batteries are lightweight, recyclable, and can last up to 45 miles on electricity alone. They also have the added benefit of being faster than standard hybrids.

In terms of safety, hybrid vehicles have as much safety as comparable gas vehicles. Unlike their gas-powered counterparts, hybrids are not a significant concern for rescuers or passengers in a crash. A metal case protects them and has a high level of insulation. Toyota places battery packs near the rear axle to ensure they are fully protected in a collision. Hybrids also shroud their battery cables in the bright orange cladding.

While the technology behind lithium-ion batteries is still evolving, it has the potential to become a vital part of the future of energy production. The EPA recently approved a $1.5 billion grant to help develop the lithium-ion industry in the US. The European Commission’s new lithium raw materials strategy aims to increase the supply of lithium in Europe by 18-fold by 2030 and reduce dependence on third-party countries.

Embora os veículos híbridos possam economizar combustível, eles também podem reduzir as emissões de carbono. As baterias de chumbo-ácido usadas em carros híbridos têm o maior nível de emissão e são as mais caras. Esses materiais tóxicos também são pesados e retardam o desempenho dos carros híbridos. Para minimizar esse problema, os fabricantes estão substituindo as baterias de chumbo-ácido por baterias de níquel-hidreto metálico. Há também diferenças de desempenho entre as baterias híbridas de chumbo-ácido e de íons de lítio.

Enquanto as baterias de cobalto e de íons de lítio estão se tornando mais populares, surgiram preocupações sobre a sustentabilidade de seu fornecimento. Altas concentrações geopolíticas de cobalto e lítio e o rápido aumento da cadeia de suprimentos levaram a questões sobre como os materiais podem ser produzidos de forma sustentável. Mas tudo isso é esperado com o rápido desenvolvimento do mercado de EV. Por enquanto, essas tecnologias estão fornecendo energia suficiente para veículos híbridos.
