Overview

Powering the lithium-ion battery life cycle

The world is making major strides
toward achieving a carbon-negative society and circular economy

Transitioning to a carbon-negative phase is a crucial step in achieving carbon neutrality.
Acceleration of efforts to shift to a circular economy via supply-chain restructuring
Enforcement of new regulations and
standards drives such efforts

Eco-friendly lithium-ion batteries

Lithium-ion batteries are essential for promoting the utilization of renewable energy and other environmentally friendly energy sources.
As the demand for batteries increases, issues related to the overall lithium-ion battery life cycle have emerged including the need to secure safety, further improve performance, and reuse and recycling of used batteries.

Hitachi High-Tech provides
comprehensive solutions for the battery value chain,
from upstream to downstream processes.
By providing support related to the overall lithium-ion battery product life cycle, we contribute to achieving carbon neutrality and a circular economy.

Creating, using, and recycling lithium-ion batteries

Establishing a suitable lithium-ion battery value chain is essential to promote a more stable supply of battery materials and safety measures.

Hitachi High-Tech’s core technological capabilities

Analytical technologies that support observation, measurement, and analysis

Analytical ability
We respond to various needs, including highly precise observation and defect analysis.
- Separator microstructure observation
  
  Our systems enable observation using ultrahigh-resolution images. The above image was taken at 80,000 times magnification and enables the viewer to see the separator’s surface microstructure.
- Ultra-low-acceleration SEM observation of cathode material
  
  This SEM image of lithium-ion battery cathode material was observed using an irradiation voltage of 10 volts. Our systems make it easy to observe the outermost surfaces of such materials at ultra-low accelerations.
- Detection of metal particles
  
  By performing an acceptance inspection of the cathode material, anode material, and conductive agent, you can understand the number, size, and elements of metal particle contaminants per weight. You can also understand metal particle contaminants at the time of acceptance and predict the defect rate of the finished products.
