6 FAQs about [Battery positive electrode technology]

Can electrode processing improve battery cyclability?

Advanced electrode processing technology can enhance the cyclability of batteries, cut the costs (Wood, Li, & Daniel, 2015), and alleviate the hazards on environment during manufacturing LIBs at a large scale (Liu et al., 2020c; Wood et al., 2020a; Zhao, Li, Liu, Huang, & Zhang, 2019).

What are the recent trends in electrode materials for Li-ion batteries?

This mini-review discusses the recent trends in electrode materials for Li-ion batteries. Elemental doping and coatings have modified many of the commonly used electrode materials, which are used either as anode or cathode materials. This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity.

What is the positive electrode material for nickel-metal hydride batteries?

Spherical nickel hydroxide with a diameter of about 10μm, which has a high filling property, is used as the positive electrode material for nickel-metal hydride batteries.

What are the characteristics of positive electrodes?

Very often, it comes directly from the name of the positive electrode active material. To compare these options, the characteristics used in the previous figure are generally used (specific power, specific energy, cost, life, safety). For the battery life, two main characteristics are to be considered : Cycle life: aging in use.

Why do lithium-ion batteries use positive electrode state of charge (SOC P)?

In lithium-ion batteries, the positive electrode generally limits the performance of the battery, because with a lower aerial capacity compared to the negative one. Hence, we decide to use the positive electrode state of charge (SOC p) for performance evaluation.
