✦ Synopsis

Alkaline aqueous electrolyte miniature batteries, and nonaqueous electrolyte-lithium miniature batteries are compared with respect to constructional features, energy density, rate capability, self-discharge, reliability, and seals. The criteria for valid comparison of such data are discussed.

1. Introduction

Progress in reducing the power requirements of electronic circuits has led to an increased demand for smaller and smaller batteries. The present world market for miniature batteries, mostly of the so-called "button cell" type, is estimated to approach 1 billion items per year. Most applications are to pocket calculators, watches and clocks, hearing aids, cameras, telecommunication and military equipment, instruments, entertainment articles and toys.

Alkaline electrolyte battery systems such as HgO-Zn, AgsO-Zn, AgO-Zn, MnOs-Zn, and air-Zn still dominate the field, but lithium battery systems of a bewildering number of types, such as MnOs-Li, CF,-Li,
