Battery Division

Overview

We at Naya are preparing an end to end solution from Cell Development to building a comprehensive capability to develop a plug & play module for companies aspiring to Develop BEVs both domestically & overseas. Our unique proposition & R&D Centre will assist companies from Battery Selection, Design & Module Delivery offering a ready to use solution for their vehicles. The key pillars at our Battery Division is Energy Density, Commercialization of new Battery Chemistries & to build a capability to break that USD 100/KWh barrier which is increasingly become the goal to increase widespread adoption of BEVs.

Market Size

The Addressable & market size is increasingly on the rise & is expected to expand many folds in the coming years. It has become a race to not only build capacity but to also continuously innovate in the Material Chemistries & typically the Cathode Materials. The applications known today may be redundant tomorrow with newer chemistries being explored by peers globally. The goal is not only to build a company to stay ahead of the curve but to also innovate new chemistries to ultimately reach the tipping point or the so called ‘Holy Grail’ in battery chemistries.

Applications

The Use of Lithium Iron Phosphate (LFP) & Nickel Manganese Cobalt (NMC) already have a widespread usage in a number of applications spread over a number of industries. Our goal is to develop unique solutions for an increasing application to accelerate the adoption of BEVs across industries.

The Naya Cell

The Cylindrical Cells are used by a number of Industry Leaders as the most viable solution for BEVs & PHEVs . The Lithium Iron Phosphate (LFP) and Nickel Manganese Cobalt (NMC) technologies offer high powered cell performance compatible with virtually any application to deliver more power and significantly increased cycle life.

Advantages

  • Low self-discharge rate
  • Wide working temperature
  • Flexibility to Increase Capacity
  • High charge & discharge current
  • Long cycle life
  • Superior safety
  • Smaller size
  • Lighter Weight

The Two most commonly used Cylindrical Cells are the 18650 & 2170 types & keeping in line with the ever changing narrative, we are also working on Developing a new proprietary Cylindrical Cell inspired by the 4680 Cell Design for maximum efficiency & effectiveness.

Type Size Capacity Weight Energy Density
18650 Diameter 18mm
Length 65mm
2200-3600 mAh 45-48g 250WH/KGS
21700 Diameter 21mm
Length 70mm
3000-4800 mAh 60-65g 300WH/KGS

Battery Design & Deployment

We have an in-house capability to Design & Develop Battery Solutions for a large number of applications

The Production & Assembly Plant

Our State-of-the-Art battery plant is presently under construction & will offer a completely integrated solution from Cutting to Module Assembly & Testing

The Naya Battery Management System

We have developed our home grown & locally developed Battery Management System in collaboration with a number of Universities throughout the country. This will offer a comprehensive protection to the battery.

The Solid-State Battery Project

The Solid-State Battery is regarded as the Holy Grail in Battery Development & Manufacturing as this would eliminate some of the major obstacles associated with Liquid Electrolyte which are used more frequently today.

Some of the key features for a Solid-State Battery are below

  • The Liquid Electrolyte Substituted with a solid electrolyte which is mainly two systems of organic and inorganic ceramic materials, the distance between the positive and negative electrodes can be reduced to a few microns which is will largely reduce the thickness of the Overall Battery
  • The Solid State Batteries will be both light & thin as the degree of flexibility of the all Solid Battery will be significantly improved
  • The Overall Energy Density of the Battery will also be significantly improved as using an all-solid electrolyte, the applicable material system of the lithium ion battery will also change, and the metal lithium will be directly used as the negative electrode which will in turn reduce the amount of the negative electrode material.
  • A Traditional lithium battery usually has the following negatives namely
    • Lithium dendrites may occur when working at high currents, causing short-circuit damage by piercing the diaphragm.
    • Side reactions, oxidative decomposition, gas generation, and combustion occur at high temperatures. In an all solid-state battery technology, the above two problems can be directly solved

Key Advantage using a Naya Battery Solution

We have aspired to make our batteries increasingly efficient, safe to use & build on years of R&D to offer solutions that can be accepted as the new norm for companies building PHEVS & BEVs globally.

The Metal-Air Battery Project

We have extensively developed solutions for the ultimate viability of Metal Air compositions with the most suited being Zinc-Air.

Advantages of Zinc Air

  • A fraction of the price of competing batteries (almost 10 times)
  • Cost between USD$ 25 – USD$ 35 per kWh(90% Cheaper than Lithium-Ion & 70% Cheaper than Lead Acid)
  • Safest & Clean
  • High Energy Density
  • Very suitable for the Warm Climatic Condition

Potential of Zinc Air

Zinc Air technology has been around for years, but cycling has remained an unfeasible challenge, until now. Blending this low-cost technology with the capability of recharging, this has brought about a paradigm shift to the biggest battery markets in the world: Lead-Acid and Lithium-Ion. These batteries are cheaper, greener, and safer than their counterparts, Lithium-Ion and Lead-Acid.

Cell Development

The below illustration is a typical Zinc Air Cell we have been working on to better understand the potential in this metal air solution
