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 are positive electrodes made of?

Positive electrodes made of lead-calcium-tin alloy. Lead, tin, and calcium were the three main components. Other elements constitute ~0.02 wt% of the sample. Corrosion potential and current, polarization resistance, electrolyte conductivity, and stability were studied.

How much energy does a positive electrode produce?

This positive electrode produces an energy density of 820 W h kg –1, achieved by harnessing a large reversible capacity with relatively small voltage hysteresis on electrochemical cycles. Moreover, voltage decay for cycling, as observed for Li-excess Mn-based electrode materials, is effectively mitigated.

How can electrode materials improve battery performance?

Some important design principles for electrode materials are considered to be able to efficiently improve the battery performance. Host chemistry strongly depends on the composition and structure of the electrode materials, thus influencing the corresponding chemical reactions.
