Scaling Up Pilot Production of Nanporous Membranes for Battery Storage Technologies
Document Type
NOE - Notice of Exemption
Document Description
The purpose of this project is to scale-up production of an advance battery membrane platform for market facilitation of safe, low-cost, and energy-dense batteries. The approach is to establish optimal processes for each key component of the membrane (polymer, polymer ink and roll-to-roll coating) to generate quality assurance and quality control metrics that will led to an in-house low rate initial production of the membrane for batteries. The intent is to establish that steady commercialized platform technology that will create multiple market opportunities in a variety of battery chemistries. The benefits of the project, as related to the California Investor-Owned Utility electricity ratepayers, are to increase grid resiliency, reduce financial burden for electricity services, and improved safety by reducing greenhouse gas emissions. Successful execution of this project will be accelerating the deployment of zero-emission electric vehicles and grid-scale storage of low-cost renewable energy at massive scale in California.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Reasons for Exemption
The reason for the CEQA categorical exemptions are as follows: 1. For Cal. Code Regs. (CCR), Title 14, Section 15301: This project will involve manufacturing and product testing to be performed at existing laboratory facilities and large commercial/institutional stake-holder facilities. This project will install small-scaled equipment into an existing facility, but will have no to minor alterations to the facility. The tests that will be performed are temporary in nature and -will require only minor alternations to existing structures. Work under this project will result in negligible or no expansion of the existing use of facilities at which testing will occur. This project will result in no significant impact to the environment and is exempt pursuant to CCR, 14 § 15301.
