The lithium-ion battery market is projected to grow at a CAGR of 13.7% between 2017 and 2022, to a value of USD 67.7 billion. As consumer demand grows for battery-enabled technology, manufacturers are investing in battery research and development, with the goal of speeding the advancement of energy density in lithium-ion batteries.
For most batteries, there are active and inactive materials on both the anode and cathode sides of the cell. There are two main ways to maximize energy density – 1) use active materials that can store more energy; 2) increase the percentage of active material in the cell compared to its inactive materials. Anode Active Materials
Strategies such as improving the active material of the cathode, improving the specific capacity of the cathode/anode material, developing lithium metal anode/anode-free lithium batteries, using solid-state electrolytes and developing new energy storage systems have been used in the research of improving the energy density of lithium batteries.
In order to achieve high energy density batteries, researchers have tried to develop electrode materials with higher energy density or modify existing electrode materials, improve the design of lithium batteries and develop new electrochemical energy systems, such as lithium air, lithium sulfur batteries, etc.
Current Li-ion batteries based on intercalation cathode chemistry leave relatively little room to further enhance the energy density because the specific capacities of these cathodes approach the theoretical levels. Increasing the cell output voltage is a possible direction to largely increase the energy density of batteries.
The electrode material determines the volume energy density of the battery, so the volume energy density of the battery is forced to increase under the condition that the battery material system and volume are unchanged, which is bound to use thinner separator materials [, , ].
Alternatively, an increase in the cell voltage obtained by using a high-potential cathode paired with a low-potential Li-metal or graphite anode can more effectively enhance the energy density of the Li (ion) battery compared with the strategy of increasing the electrode capacity. 8, 12
