Power consumption diagram of lithium battery

How can lithium-ion batteries improve energy storage per kg?

Updating the graphite anode with silicone and moving from current NMC333 towards NMC622 or NMC811 is the most likely short term improvements to lithium-ion batteries. Together with the improvements in other cell components, like improved electrolyte, this will be a first step towards better energy storage per kg.

What electronic components consume power in a battery pack?

The main electronic components that consume power in a battery pack include Battery Management System (BMS) Integrated Circuit (IC), protection transistors, pull up resistors, microcontroller, and other ICs that are part of the pack. Self-drain power consumption has a critical impact on storage life.

How are life cycle assessments of lithium-ion batteries structured?

The report is largely structured based on a number of questions. The questions are divided in two parts, one focusing on short-term questions and the second on more long-term questions. To sum up the results of this review of life cycle assessments of lithium-ion batteries we used the questions as base.

Why is recycling of lithium-ion batteries so low?

Recycling of lithium-ion batteries is currently low at best. This cannot be ascribed only to the lack of economic incentive inherent in the battery chemistries, it also has to do with very small battery volumes reaching end of life, poor knowledge of battery content and design, and lack of proper marking of the packs and cells.

How can legislative actions affect the future of lithium-ion batteries?

There is great potential to influence the future impact by legislative actions, especially in the area of recycling. Today there is no economic incentive for recycling of lithium-ion batteries, but by placing the correct requirements on the end of life handling we can create this incentive.

Why do lithium-ion batteries use a lot of electricity?

The largest part of the energy use in the production of lithium-ion batteries comes from electricity use. Because of this the electricity mix is a critical factor for the greenhouse gas emissions from production.
